Calibration Time, Come On! [Encore Publication]: Why you should color-calibrate your display devices and how to do it

We tend to take for granted that the colors we perceive when we look at a scene will be captured faithfully by our camera’s sensor and the lens in front of it, and then rendered accurately in every stage of processing thereafter, from the memory card to the computer and to all our displays including laptops, tablets, smartphones, TVs, projectors, and even on these same types of displays owned by our friends with whom we share our images.  (We also expect prints made from our images to faithfully reproduce the colors from our camera’s sensor, but that is a story for another day.)

As photographers, we want to ensure the colors in our final images reflect as best we can the original colors we perceived when first framing the scene.  With proper color-calibration of the display screens we use to process our images, we can keep the colors as true and accurate as possible.  Buy this photo

The reality is that every step of the process of capturing, processing, and sharing an image leads to changes in the rendition of the colors.  No device can fully represent every intensity of every color that the human eye can see.  Camera manufacturers go to great lengths to ensure the colors captured by the camera’s sensor are as accurate as possible when you attach a lens made by the same company.  And when you use software such as Lightroom or Photoshop to post-process your images, you may take great pains to ensure the colors you see on your screen look very close to what you remember you saw when you shot the image in the first place.  But without careful attention, the final image we see later on our various display screens can look very different from device to device.  That’s because every type of display, and even every individual screen, has a unique way of representing every color.  So your PC’s monitor will display any given color just a bit differently than your phone’s screen will show that color.  And your friend’s phone’s screen will look a bit different, still (even if it’s the exact same brand and model as yours).

Fortunately, there is a simple and quite affordable way to standardize the representation of colors across all your devices.  It’s called color calibration, and for less than the cost of a good polarizing filter, say about $100, you can purchase a little doodad that can calibrate all your displays.  I use the X-Rite ColorMunki, which can be had for about $110 at retail.

To use a color calibration device, you install some software on your display(s) and then place the device on your display screen.  The software cycles the screen through displaying a wide range of colors, which are read and recorded by the calibration device.  Finally, the needed adjustments to bring your screen’s settings into line so they render colors as accurately as possible are saved in a special file.  From this point on, whenever your display device is started up, it reads the configuration information in that file and renders colors as closely to their actual appearance as it is physically capable of doing.

Because our eyes perceive colors differently in different ambient light conditions, you’ll want to have your calibration device take an ambient light reading for the typical lighting conditions that will be present while you’re using each display.  For example, if you use your laptop PC mostly when bright daylight is streaming into your kitchen, you’ll want to calibrate when those conditions are present.  You can even save different versions of the configuration file for different lighting conditions.

And because display devices do change over time, it’s a good idea to re-calibrate each device every few weeks to control for that.

If you’re serious about your photography, you want your images to look great not only on your own display screen(s), but also when viewed by other people on other types of devices or on the printed page.  Using a reliable color-calibration device helps ensure the colors in your images remain as accurate as possible through all the stages of processing and sharing until they leave your personal control.  This is a good practice that all photographers should employ.

Camera Pixels App [Encore Publication]: Significant improvements in the new version make this a best-in-class app

Note: It’s been over a year since I first posted  this updated review.  I still find the Camera Pixels app to be a top-performing app in its class, and I still use it regularly to take manual control of my iPhone camera, so thought I’d post the review again now.

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

About three months ago, I posted a review of an early version of an iPhone app called “Camera Pixels”.  In that review, I found the app to be a very promising concept due to its advanced DSLR-like features and intuitive controls, but I couldn’t fully endorse it in the earlier version because I found several bugs and interface quirks.  You can read that earlier review here: Previous review of early version of Camera Pixels app.  Since that review was published, I have had several discussions with the Camera Pixels support team to detail my concerns about the various issues I found.

For the past two days I have been testing a new version of the Camera Pixels app, and I can now recommend it wholeheartedly.  The new release preserves the advanced features and (relatively) simple interface of the earlier version, but it has addressed all of the significant issues I outlined in my review of the previous release.  Specifically:

  • the image flicker in the “viewfinder” area of the screen has been eliminated,
  • the bracketing of exposures now retains the proper requested spacing (unless at a physical limit of a setting),
  • there is a new “Pro View” mode that keeps the manual settings toolbar always on the screen so any manual overrides are immediately apparent, and
  • the controls to separate the exposure point from the focus point are now more intuitive.

Like the “Manual” camera app that I’ve been using for years and the “ProCam 4” app that has been my go-to camera control app for the past several months, the new “Camera Pixels” app allows the manual selection of ISO, shutter speed, exposure compensation, and focus distance (note that the iPhone camera’s lens has a fixed aperture, so F-stop cannot be manually set).  Also like the Manual app and the ProCam 4 app, Camera Pixels allows images to be captured using RAW mode, which has a great many advantages over capture in JPEG format (see this post for more information: Post on RAW Capture).  And all three of these camera apps display a histogram to assist in setting exposure properly.  

In addition, both Camera Pixels and ProCam 4 (but not Manual) offer some very useful advanced camera control capabilities, including the following:

  • Shutter Priority: You can choose an exposure mode in which you select the shutter speed first and the app will set the appropriate ISO.
  • Exposure Bracketing: You can shoot a series of four shots at different exposures to increase the likelihood that one of them will be at the best exposure for the lighting conditions.  The series of shots can also be combined using HDR tools found in Lightroom, Photoshop, and other editing software into a single image with a higher range of tones from very dark to very bright.
  • White Balance: You can adjust white balance in the app, which is often preferable to having to adjust it in your RAW files during post-processing.
  • Virtual Horizon: The display can show you when the horizon is level.
  • Slow Shutter Options: You can select long fixed shutter speeds as well as bulb mode to keep the shutter open for as long as you’d like.
  • RAW+JPEG: You can choose to store the image in both RAW and JPEG formats.

With all this incremental functionality, your little phone’s camera begins to behave a lot like a more advanced standalone camera.  While the iPhone’s camera, with its small sensor and its tiny fixed-aperture non-interchangeable lens, still cannot compare to a professional or enthusiast DSLR or ILC camera, the results using an advanced manual camera control app such as Camera Pixels or ProCam 4 are vastly improved compared to using the phone’s native camera app.  At iTunes App Store pricing of $2.99 for Camera Pixels or $4.99 (temporarily reduced to $1.99) for ProCam 4, either of these apps is a great buy and a serious enhancement to the iPhone’s built-in camera.

There are some significant differences between Camera Pixels and ProCam 4.  ProCam 4 offers advanced image editing capabilities, while Camera Pixels does not.  However, Camera Pixels offers more flexible exposure bracketing options, the ability to separate exposure point from focus point, a better histogram, and more advanced RAW and video shooting options.  And a significant advantage of the new Camera Pixels app over ProCam 4 is its simple and intuitive user interface for setting and resetting the manual camera control features such as exposure compensation, shutter priority, and ISO priority.  In fact, the Camera Pixels app comes the closest I’ve ever found to the user interface of an advanced DSLR or mirrorless camera.

One note to enhance the usability of the Camera Pixels app: As far as I can tell, there is no built-in help content in the app itself, but there is a very useful online user guide available from the app’s developers.  You can find the user guide here: Camera Pixels app user guide.

In summary, the new Camera Pixels app is a great concept that comes closest of any camera control app I’ve found to the look-and-feel of an advanced standalone camera.  With the greatly improved new release, Camera Pixels has become the best option I’ve found for iPhone users wishing to control the phone’s built-in camera like an advanced DSLR or mirrorless standalone camera.  I now fully recommend this app, and I plan to use it as my first choice for advanced control of my iPhone’s camera.

Chromatica App [Encore Publication]: Simple, intuitive, and affordable, this new iPhone camera control app is a winner

LR chromatica screenshot-

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

There are dozens of camera control apps available for the iPhone, and it can be confusing to figure out which one is right for you.  In the past, I’ve reviewed the following apps: Manual (see post on Manual app), ProCam 4 (see post on ProCam 4 app), and Camera Pixels (see post on Camera Pixels app).  In today’s post I offer a first look at a new app, Chromatica, from the same company that developed Camera Pixels.

Chromatica, priced at an appealing $2.99 on the Apple App Store, is aimed for a middle market of photographers who want more manual control than the camera’s native (built-in) app can provide but without the complexity of more enthusiast-level apps, such as Camera Pixels or ProCam 5 (the successor to ProCam 4).  It competes with other mid-level camera control apps such as Manual, though it is priced at $1 less.  My initial testing of the new Chromatica app found it to be a very worthy tool for most users to take control of their iPhone photography without the expense or complexity of the more advanced apps.  Chromatica has a very simple and intuitive interface, offers the ability to shoot in RAW mode for much higher quality images, and provides the basic required functionality to take manual control over your camera.  It doesn’t offer the full suite of bells and whistles found in the more sophisticated apps, but it’s still a powerful tool that makes the iPhone camera act much more like a DSLR or mirrorless camera while providing a clean and simple user interface.

Chromatica’s features include the ability to shoot in either auto or one of several manual modes such as Shutter Priority and ISO Priority.  It’s quite easy to realize which mode you’re in and to return to auto mode when you’re done taking manual control over the camera; the same cannot be said of some other camera control apps I’ve used.  Another essential feature is the ability to separate the exposure and focus points, so that exposure can be set based on one part of the image while focus is set on another part.  There doesn’t seem to be any user manual or in-app help function to explain this feature, so here’s how it works: simply touch the screen with two fingers and you’ll see a circle and a square appear.  Move the circle to the point in the image where you want to set exposure, and move the square to the point where you want to set focus.  Other useful features include an exposure histogram to show you the range of brightness levels in your shot, and exposure clipping to flag the areas of the image that are too bright or too dim.  Chromatica includes full optical stabilization in RAW mode as well as focus peaking to aid in manual focus operations.

What you won’t find in Chromatica, but for most photo-making purposes won’t miss, are advanced image-editing tools (instead, find these in your favorite standalone image editing software such as Lightroom or Photoshop), exposure bracketing, and long-exposure camera control modes.  Other more sophisticated apps do offer these and more features, but at the expense of higher cost and greater complexity.

In short, Chromatica does exactly what it’s designed to do: make it simple and quick to manually control your phone’s camera and make the most of it’s capabilities.  For most casual and enthusiast photographers, this is good enough when using a phone’s camera.  I typically shoot with professional DSLR gear costing many thousands of dollars when I need pro-level results, but I love the convenience and ease of grabbing some quick shots with my phone, and in the future I am likely to use Chromatica to control the phone’s camera when it’s a straightforward capture.  I’ll continue to use Camera Pixels and ProCam 5 when I require more advanced features to control the phone.

Here’s the link to the Chromatica app on the Apple App Store: Chromatica app.

For reference, here are some popular iPhone camera control apps along with their price and brief notes:

  • Native iOS Camera app (Free): Comes built-in with the iPhone.  Does not allow RAW capture, manual control of the camera, or any advanced features, but does allow the separation of focus and exposure points.
  • Camera Pixels Lite (Free): An entry-level version of Camera Pixels that offers basic camera control features but does not allow RAW capture.
  • Manual ($3.99): Another entry-level app that is really starting to show its age.  Offers basic camera control features including RAW capture, but lacks more advanced features and is difficult to use.
  • Chromatica ($2.99): A great value and very easy to use, this app offers camera control features, RAW capture, and a few more advanced features.
  • Camera Pixels ($3.99): A powerful manual control app with a very wide range of features, it remains quite intuitive to use.
  • ProCam 5 ($5.99): A very powerful app with a wide range of camera control features plus more sophisticated functionality typically associated with DSLRs and mirrorless cameras.  Also includes a full suite of image editing tools.  It can be difficult to use.  Note: I’ve only tested the older ProCam 4.
  • Pro Camera ($5.99): A popular higher-end app with a full range of features.  Note: I’ve not yet tested this app.

Because our eyes perceive colors differently in different ambient light conditions, you’ll want to have your calibration device take an ambient light reading for the typical lighting conditions that will be present while you’re using each display.  For example, if you use your laptop PC mostly when bright daylight is streaming into your kitchen, you’ll want to calibrate when those conditions are present.  You can even save different versions of the configuration file for different lighting conditions.

And because display devices do change over time, it’s a good idea to re-calibrate each device every few weeks to control for that.

If you’re serious about your photography, you want your images to look great not only on your own display screen(s), but also when viewed by other people on other types of devices or on the printed page.  Using a reliable color-calibration device helps ensure the colors in your images remain as accurate as possible through all the stages of processing and sharing until they leave your personal control.  This is a good practice that all photographers should employ.

Camera Pixels App [Encore Publication]: Significant improvements in the new version make this a best-in-class app

Note: It’s been over a year since I first posted  this updated review.  I still find the Camera Pixels app to be a top-performing app in its class, and I still use it regularly to take manual control of my iPhone camera, so thought I’d post the review again now.

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

About three months ago, I posted a review of an early version of an iPhone app called “Camera Pixels”.  In that review, I found the app to be a very promising concept due to its advanced DSLR-like features and intuitive controls, but I couldn’t fully endorse it in the earlier version because I found several bugs and interface quirks.  You can read that earlier review here: Previous review of early version of Camera Pixels app.  Since that review was published, I have had several discussions with the Camera Pixels support team to detail my concerns about the various issues I found.

For the past two days I have been testing a new version of the Camera Pixels app, and I can now recommend it wholeheartedly.  The new release preserves the advanced features and (relatively) simple interface of the earlier version, but it has addressed all of the significant issues I outlined in my review of the previous release.  Specifically:

  • the image flicker in the “viewfinder” area of the screen has been eliminated,
  • the bracketing of exposures now retains the proper requested spacing (unless at a physical limit of a setting),
  • there is a new “Pro View” mode that keeps the manual settings toolbar always on the screen so any manual overrides are immediately apparent, and
  • the controls to separate the exposure point from the focus point are now more intuitive.

Like the “Manual” camera app that I’ve been using for years and the “ProCam 4” app that has been my go-to camera control app for the past several months, the new “Camera Pixels” app allows the manual selection of ISO, shutter speed, exposure compensation, and focus distance (note that the iPhone camera’s lens has a fixed aperture, so F-stop cannot be manually set).  Also like the Manual app and the ProCam 4 app, Camera Pixels allows images to be captured using RAW mode, which has a great many advantages over capture in JPEG format (see this post for more information: Post on RAW Capture).  And all three of these camera apps display a histogram to assist in setting exposure properly.  

In addition, both Camera Pixels and ProCam 4 (but not Manual) offer some very useful advanced camera control capabilities, including the following:

  • Shutter Priority: You can choose an exposure mode in which you select the shutter speed first and the app will set the appropriate ISO.
  • Exposure Bracketing: You can shoot a series of four shots at different exposures to increase the likelihood that one of them will be at the best exposure for the lighting conditions.  The series of shots can also be combined using HDR tools found in Lightroom, Photoshop, and other editing software into a single image with a higher range of tones from very dark to very bright.
  • White Balance: You can adjust white balance in the app, which is often preferable to having to adjust it in your RAW files during post-processing.
  • Virtual Horizon: The display can show you when the horizon is level.
  • Slow Shutter Options: You can select long fixed shutter speeds as well as bulb mode to keep the shutter open for as long as you’d like.
  • RAW+JPEG: You can choose to store the image in both RAW and JPEG formats.

With all this incremental functionality, your little phone’s camera begins to behave a lot like a more advanced standalone camera.  While the iPhone’s camera, with its small sensor and its tiny fixed-aperture non-interchangeable lens, still cannot compare to a professional or enthusiast DSLR or ILC camera, the results using an advanced manual camera control app such as Camera Pixels or ProCam 4 are vastly improved compared to using the phone’s native camera app.  At iTunes App Store pricing of $2.99 for Camera Pixels or $4.99 (temporarily reduced to $1.99) for ProCam 4, either of these apps is a great buy and a serious enhancement to the iPhone’s built-in camera.

There are some significant differences between Camera Pixels and ProCam 4.  ProCam 4 offers advanced image editing capabilities, while Camera Pixels does not.  However, Camera Pixels offers more flexible exposure bracketing options, the ability to separate exposure point from focus point, a better histogram, and more advanced RAW and video shooting options.  And a significant advantage of the new Camera Pixels app over ProCam 4 is its simple and intuitive user interface for setting and resetting the manual camera control features such as exposure compensation, shutter priority, and ISO priority.  In fact, the Camera Pixels app comes the closest I’ve ever found to the user interface of an advanced DSLR or mirrorless camera.

One note to enhance the usability of the Camera Pixels app: As far as I can tell, there is no built-in help content in the app itself, but there is a very useful online user guide available from the app’s developers.  You can find the user guide here: Camera Pixels app user guide.

In summary, the new Camera Pixels app is a great concept that comes closest of any camera control app I’ve found to the look-and-feel of an advanced standalone camera.  With the greatly improved new release, Camera Pixels has become the best option I’ve found for iPhone users wishing to control the phone’s built-in camera like an advanced DSLR or mirrorless standalone camera.  I now fully recommend this app, and I plan to use it as my first choice for advanced control of my iPhone’s camera.

Chromatica App [Encore Publication]: Simple, intuitive, and affordable, this new iPhone camera control app is a winner

LR chromatica screenshot-

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

There are dozens of camera control apps available for the iPhone, and it can be confusing to figure out which one is right for you.  In the past, I’ve reviewed the following apps: Manual (see post on Manual app), ProCam 4 (see post on ProCam 4 app), and Camera Pixels (see post on Camera Pixels app).  In today’s post I offer a first look at a new app, Chromatica, from the same company that developed Camera Pixels.

Chromatica, priced at an appealing $2.99 on the Apple App Store, is aimed for a middle market of photographers who want more manual control than the camera’s native (built-in) app can provide but without the complexity of more enthusiast-level apps, such as Camera Pixels or ProCam 5 (the successor to ProCam 4).  It competes with other mid-level camera control apps such as Manual, though it is priced at $1 less.  My initial testing of the new Chromatica app found it to be a very worthy tool for most users to take control of their iPhone photography without the expense or complexity of the more advanced apps.  Chromatica has a very simple and intuitive interface, offers the ability to shoot in RAW mode for much higher quality images, and provides the basic required functionality to take manual control over your camera.  It doesn’t offer the full suite of bells and whistles found in the more sophisticated apps, but it’s still a powerful tool that makes the iPhone camera act much more like a DSLR or mirrorless camera while providing a clean and simple user interface.

Chromatica’s features include the ability to shoot in either auto or one of several manual modes such as Shutter Priority and ISO Priority.  It’s quite easy to realize which mode you’re in and to return to auto mode when you’re done taking manual control over the camera; the same cannot be said of some other camera control apps I’ve used.  Another essential feature is the ability to separate the exposure and focus points, so that exposure can be set based on one part of the image while focus is set on another part.  There doesn’t seem to be any user manual or in-app help function to explain this feature, so here’s how it works: simply touch the screen with two fingers and you’ll see a circle and a square appear.  Move the circle to the point in the image where you want to set exposure, and move the square to the point where you want to set focus.  Other useful features include an exposure histogram to show you the range of brightness levels in your shot, and exposure clipping to flag the areas of the image that are too bright or too dim.  Chromatica includes full optical stabilization in RAW mode as well as focus peaking to aid in manual focus operations.

What you won’t find in Chromatica, but for most photo-making purposes won’t miss, are advanced image-editing tools (instead, find these in your favorite standalone image editing software such as Lightroom or Photoshop), exposure bracketing, and long-exposure camera control modes.  Other more sophisticated apps do offer these and more features, but at the expense of higher cost and greater complexity.

In short, Chromatica does exactly what it’s designed to do: make it simple and quick to manually control your phone’s camera and make the most of it’s capabilities.  For most casual and enthusiast photographers, this is good enough when using a phone’s camera.  I typically shoot with professional DSLR gear costing many thousands of dollars when I need pro-level results, but I love the convenience and ease of grabbing some quick shots with my phone, and in the future I am likely to use Chromatica to control the phone’s camera when it’s a straightforward capture.  I’ll continue to use Camera Pixels and ProCam 5 when I require more advanced features to control the phone.

Here’s the link to the Chromatica app on the Apple App Store: Chromatica app.

For reference, here are some popular iPhone camera control apps along with their price and brief notes:

  • Native iOS Camera app (Free): Comes built-in with the iPhone.  Does not allow RAW capture, manual control of the camera, or any advanced features, but does allow the separation of focus and exposure points.
  • Camera Pixels Lite (Free): An entry-level version of Camera Pixels that offers basic camera control features but does not allow RAW capture.
  • Manual ($3.99): Another entry-level app that is really starting to show its age.  Offers basic camera control features including RAW capture, but lacks more advanced features and is difficult to use.
  • Chromatica ($2.99): A great value and very easy to use, this app offers camera control features, RAW capture, and a few more advanced features.
  • Camera Pixels ($3.99): A powerful manual control app with a very wide range of features, it remains quite intuitive to use.
  • ProCam 5 ($5.99): A very powerful app with a wide range of camera control features plus more sophisticated functionality typically associated with DSLRs and mirrorless cameras.  Also includes a full suite of image editing tools.  It can be difficult to use.  Note: I’ve only tested the older ProCam 4.
  • Pro Camera ($5.99): A popular higher-end app with a full range of features.  Note: I’ve not yet tested this app.

Calibration Time, Come On! [Encore Publication]: Why you should color-calibrate your display devices and how to do it

We tend to take for granted that the colors we perceive when we look at a scene will be captured faithfully by our camera’s sensor and the lens in front of it, and then rendered accurately in every stage of processing thereafter, from the memory card to the computer and to all our displays including laptops, tablets, smartphones, TVs, projectors, and even on these same types of displays owned by our friends with whom we share our images.  (We also expect prints made from our images to faithfully reproduce the colors from our camera’s sensor, but that is a story for another day.)

As photographers, we want to ensure the colors in our final images reflect as best we can the original colors we perceived when first framing the scene.  With proper color-calibration of the display screens we use to process our images, we can keep the colors as true and accurate as possible.  Buy this photo

The reality is that every step of the process of capturing, processing, and sharing an image leads to changes in the rendition of the colors.  No device can fully represent every intensity of every color that the human eye can see.  Camera manufacturers go to great lengths to ensure the colors captured by the camera’s sensor are as accurate as possible when you attach a lens made by the same company.  And when you use software such as Lightroom or Photoshop to post-process your images, you may take great pains to ensure the colors you see on your screen look very close to what you remember you saw when you shot the image in the first place.  But without careful attention, the final image we see later on our various display screens can look very different from device to device.  That’s because every type of display, and even every individual screen, has a unique way of representing every color.  So your PC’s monitor will display any given color just a bit differently than your phone’s screen will show that color.  And your friend’s phone’s screen will look a bit different, still (even if it’s the exact same brand and model as yours).

Fortunately, there is a simple and quite affordable way to standardize the representation of colors across all your devices.  It’s called color calibration, and for less than the cost of a good polarizing filter, say about $100, you can purchase a little doodad that can calibrate all your displays.  I use the X-Rite ColorMunki, which can be had for about $110 at retail.

Calibration Time, Come On! [Encore Publication]: Why you should color-calibrate your display devices and how to do it

We tend to take for granted that the colors we perceive when we look at a scene will be captured faithfully by our camera’s sensor and the lens in front of it, and then rendered accurately in every stage of processing thereafter, from the memory card to the computer and to all our displays including laptops, tablets, smartphones, TVs, projectors, and even on these same types of displays owned by our friends with whom we share our images.  (We also expect prints made from our images to faithfully reproduce the colors from our camera’s sensor, but that is a story for another day.)

As photographers, we want to ensure the colors in our final images reflect as best we can the original colors we perceived when first framing the scene.  With proper color-calibration of the display screens we use to process our images, we can keep the colors as true and accurate as possible.  Buy this photo

The reality is that every step of the process of capturing, processing, and sharing an image leads to changes in the rendition of the colors.  No device can fully represent every intensity of every color that the human eye can see.  Camera manufacturers go to great lengths to ensure the colors captured by the camera’s sensor are as accurate as possible when you attach a lens made by the same company.  And when you use software such as Lightroom or Photoshop to post-process your images, you may take great pains to ensure the colors you see on your screen look very close to what you remember you saw when you shot the image in the first place.  But without careful attention, the final image we see later on our various display screens can look very different from device to device.  That’s because every type of display, and even every individual screen, has a unique way of representing every color.  So your PC’s monitor will display any given color just a bit differently than your phone’s screen will show that color.  And your friend’s phone’s screen will look a bit different, still (even if it’s the exact same brand and model as yours).

Fortunately, there is a simple and quite affordable way to standardize the representation of colors across all your devices.  It’s called color calibration, and for less than the cost of a good polarizing filter, say about $100, you can purchase a little doodad that can calibrate all your displays.  I use the X-Rite ColorMunki, which can be had for about $110 at retail.

To use a color calibration device, you install some software on your display(s) and then place the device on your display screen.  The software cycles the screen through displaying a wide range of colors, which are read and recorded by the calibration device.  Finally, the needed adjustments to bring your screen’s settings into line so they render colors as accurately as possible are saved in a special file.  From this point on, whenever your display device is started up, it reads the configuration information in that file and renders colors as closely to their actual appearance as it is physically capable of doing.

Because our eyes perceive colors differently in different ambient light conditions, you’ll want to have your calibration device take an ambient light reading for the typical lighting conditions that will be present while you’re using each display.  For example, if you use your laptop PC mostly when bright daylight is streaming into your kitchen, you’ll want to calibrate when those conditions are present.  You can even save different versions of the configuration file for different lighting conditions.

And because display devices do change over time, it’s a good idea to re-calibrate each device every few weeks to control for that.

If you’re serious about your photography, you want your images to look great not only on your own display screen(s), but also when viewed by other people on other types of devices or on the printed page.  Using a reliable color-calibration device helps ensure the colors in your images remain as accurate as possible through all the stages of processing and sharing until they leave your personal control.  This is a good practice that all photographers should employ.

How do you control for color accuracy in your images?  Please share your methods here!

Chromatica App [Encore Publication]: Simple, intuitive, and affordable, this new iPhone camera control app is a winner

LR chromatica screenshot-

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

There are dozens of camera control apps available for the iPhone, and it can be confusing to figure out which one is right for you.  In the past, I’ve reviewed the following apps: Manual (see post on Manual app), ProCam 4 (see post on ProCam 4 app), and Camera Pixels (see post on Camera Pixels app).  In today’s post I offer a first look at a new app, Chromatica, from the same company that developed Camera Pixels.

Chromatica, priced at an appealing $2.99 on the Apple App Store, is aimed for a middle market of photographers who want more manual control than the camera’s native (built-in) app can provide but without the complexity of more enthusiast-level apps, such as Camera Pixels or ProCam 5 (the successor to ProCam 4).  It competes with other mid-level camera control apps such as Manual, though it is priced at $1 less.  My initial testing of the new Chromatica app found it to be a very worthy tool for most users to take control of their iPhone photography without the expense or complexity of the more advanced apps.  Chromatica has a very simple and intuitive interface, offers the ability to shoot in RAW mode for much higher quality images, and provides the basic required functionality to take manual control over your camera.  It doesn’t offer the full suite of bells and whistles found in the more sophisticated apps, but it’s still a powerful tool that makes the iPhone camera act much more like a DSLR or mirrorless camera while providing a clean and simple user interface.

Chromatica’s features include the ability to shoot in either auto or one of several manual modes such as Shutter Priority and ISO Priority.  It’s quite easy to realize which mode you’re in and to return to auto mode when you’re done taking manual control over the camera; the same cannot be said of some other camera control apps I’ve used.  Another essential feature is the ability to separate the exposure and focus points, so that exposure can be set based on one part of the image while focus is set on another part.  There doesn’t seem to be any user manual or in-app help function to explain this feature, so here’s how it works: simply touch the screen with two fingers and you’ll see a circle and a square appear.  Move the circle to the point in the image where you want to set exposure, and move the square to the point where you want to set focus.  Other useful features include an exposure histogram to show you the range of brightness levels in your shot, and exposure clipping to flag the areas of the image that are too bright or too dim.  Chromatica includes full optical stabilization in RAW mode as well as focus peaking to aid in manual focus operations.

What you won’t find in Chromatica, but for most photo-making purposes won’t miss, are advanced image-editing tools (instead, find these in your favorite standalone image editing software such as Lightroom or Photoshop), exposure bracketing, and long-exposure camera control modes.  Other more sophisticated apps do offer these and more features, but at the expense of higher cost and greater complexity.

In short, Chromatica does exactly what it’s designed to do: make it simple and quick to manually control your phone’s camera and make the most of it’s capabilities.  For most casual and enthusiast photographers, this is good enough when using a phone’s camera.  I typically shoot with professional DSLR gear costing many thousands of dollars when I need pro-level results, but I love the convenience and ease of grabbing some quick shots with my phone, and in the future I am likely to use Chromatica to control the phone’s camera when it’s a straightforward capture.  I’ll continue to use Camera Pixels and ProCam 5 when I require more advanced features to control the phone.

Here’s the link to the Chromatica app on the Apple App Store: Chromatica app.

For reference, here are some popular iPhone camera control apps along with their price and brief notes:

  • Native iOS Camera app (Free): Comes built-in with the iPhone.  Does not allow RAW capture, manual control of the camera, or any advanced features, but does allow the separation of focus and exposure points.
  • Camera Pixels Lite (Free): An entry-level version of Camera Pixels that offers basic camera control features but does not allow RAW capture.
  • Manual ($3.99): Another entry-level app that is really starting to show its age.  Offers basic camera control features including RAW capture, but lacks more advanced features and is difficult to use.

We tend to take for granted that the colors we perceive when we look at a scene will be captured faithfully by our camera’s sensor and the lens in front of it, and then rendered accurately in every stage of processing thereafter, from the memory card to the computer and to all our displays including laptops, tablets, smartphones, TVs, projectors, and even on these same types of displays owned by our friends with whom we share our images.  (We also expect prints made from our images to faithfully reproduce the colors from our camera’s sensor, but that is a story for another day.)

As photographers, we want to ensure the colors in our final images reflect as best we can the original colors we perceived when first framing the scene.  With proper color-calibration of the display screens we use to process our images, we can keep the colors as true and accurate as possible.  Buy this photo

The reality is that every step of the process of capturing, processing, and sharing an image leads to changes in the rendition of the colors.  No device can fully represent every intensity of every color that the human eye can see.  Camera manufacturers go to great lengths to ensure the colors captured by the camera’s sensor are as accurate as possible when you attach a lens made by the same company.  And when you use software such as Lightroom or Photoshop to post-process your images, you may take great pains to ensure the colors you see on your screen look very close to what you remember you saw when you shot the image in the first place.  But without careful attention, the final image we see later on our various display screens can look very different from device to device.  That’s because every type of display, and even every individual screen, has a unique way of representing every color.  So your PC’s monitor will display any given color just a bit differently than your phone’s screen will show that color.  And your friend’s phone’s screen will look a bit different, still (even if it’s the exact same brand and model as yours).

Fortunately, there is a simple and quite affordable way to standardize the representation of colors across all your devices.  It’s called color calibration, and for less than the cost of a good polarizing filter, say about $100, you can purchase a little doodad that can calibrate all your displays.  I use the X-Rite ColorMunki, which can be had for about $110 at retail.

To use a color calibration device, you install some software on your display(s) and then place the device on your display screen.  The software cycles the screen through displaying a wide range of colors, which are read and recorded by the calibration device.  Finally, the needed adjustments to bring your screen’s settings into line so they render colors as accurately as possible are saved in a special file.  From this point on, whenever your display device is started up, it reads the configuration information in that file and renders colors as closely to their actual appearance as it is physically capable of doing.

Because our eyes perceive colors differently in different ambient light conditions, you’ll want to have your calibration device take an ambient light reading for the typical lighting conditions that will be present while you’re using each display.  For example, if you use your laptop PC mostly when bright daylight is streaming into your kitchen, you’ll want to calibrate when those conditions are present.  You can even save different versions of the configuration file for different lighting conditions.

And because display devices do change over time, it’s a good idea to re-calibrate each device every few weeks to control for that.

If you’re serious about your photography, you want your images to look great not only on your own display screen(s), but also when viewed by other people on other types of devices or on the printed page.  Using a reliable color-calibration device helps ensure the colors in your images remain as accurate as possible through all the stages of processing and sharing until they leave your personal control.  This is a good practice that all photographers should employ.

Camera Pixels App (Updated Review): Significant improvements in the new version make this a best-in-class app

I’ve posted repeatedly about the importance of understanding how to take manual control of your camera in order to make images that are properly exposed and focused.  Whether you are using a professional DSLR, an advanced full-frame mirrorless ILC, a compact point-and-shoot, or the camera built into your smart phone, there is no way you will get consistently acceptable results if you leave the camera’s settings to its auto mode.  See this post for an overview: Post on Beyond the Auto Mode.

About three months ago, I posted a review of an early version of an iPhone app called “Camera Pixels”.  In that review, I found the app to be a very promising concept due to its advanced DSLR-like features and intuitive controls, but I couldn’t fully endorse it in the earlier version because I found several bugs and interface quirks.  You can read that earlier review here: Previous review of early version of Camera Pixels app.  Since that review was published, I have had several discussions with the Camera Pixels support team to detail my concerns about the various issues I found.

For the past two days I have been testing a new version of the Camera Pixels app, and I can now recommend it wholeheartedly.  The new release preserves the advanced features and (relatively) simple interface of the earlier version, but it has addressed all of the significant issues I outlined in my review of the previous release.  Specifically:

  • the image flicker in the “viewfinder” area of the screen has been eliminated,
  • the bracketing of exposures now retains the proper requested spacing (unless at a physical limit of a setting),
  • there is a new “Pro View” mode that keeps the manual settings toolbar always on the screen so any manual overrides are immediately apparent, and
  • the controls to separate the exposure point from the focus point are now more intuitive.

Like the “Manual” camera app that I’ve been using for years and the “ProCam 4” app that has been my go-to camera control app for the past several months, the new “Camera Pixels” app allows the manual selection of ISO, shutter speed, exposure compensation, and focus distance (note that the iPhone camera’s lens has a fixed aperture, so F-stop cannot be manually set).  Also like the Manual app and the ProCam 4 app, Camera Pixels allows images to be captured using RAW mode, which has a great many advantages over capture in JPEG format (see this post for more information: Post on RAW Capture).  And all three of these camera apps display a histogram to assist in setting exposure properly.  

In addition, both Camera Pixels and ProCam 4 (but not Manual) offer some very useful advanced camera control capabilities, including the following:

  • Shutter Priority: You can choose an exposure mode in which you select the shutter speed first and the app will set the appropriate ISO.
  • Exposure Bracketing: You can shoot a series of four shots at different exposures to increase the likelihood that one of them will be at the best exposure for the lighting conditions.  The series of shots can also be combined using HDR tools found in Lightroom, Photoshop, and other editing software into a single image with a higher range of tones from very dark to very bright.
  • White Balance: You can adjust white balance in the app, which is often preferable to having to adjust it in your RAW files during post-processing.
  • Virtual Horizon: The display can show you when the horizon is level.
  • Slow Shutter Options: You can select long fixed shutter speeds as well as bulb mode to keep the shutter open for as long as you’d like.
  • RAW+JPEG: You can choose to store the image in both RAW and JPEG formats.

With all this incremental functionality, your little phone’s camera begins to behave a lot like a more advanced standalone camera.  While the iPhone’s camera, with its small sensor and its tiny fixed-aperture non-interchangeable lens, still cannot compare to a professional or enthusiast DSLR or ILC camera, the results using an advanced manual camera control app such as Camera Pixels or ProCam 4 are vastly improved compared to using the phone’s native camera app.  At iTunes App Store pricing of $2.99 for Camera Pixels or $4.99 (temporarily reduced to $1.99) for ProCam 4, either of these apps is a great buy and a serious enhancement to the iPhone’s built-in camera.

There are some significant differences between Camera Pixels and ProCam 4.  ProCam 4 offers advanced image editing capabilities, while Camera Pixels does not.  However, Camera Pixels offers more flexible exposure bracketing options, the ability to separate exposure point from focus point, a better histogram, and more advanced RAW and video shooting options.  And a significant advantage of the new Camera Pixels app over ProCam 4 is its simple and intuitive user interface for setting and resetting the manual camera control features such as exposure compensation, shutter priority, and ISO priority.  In fact, the Camera Pixels app comes the closest I’ve ever found to the user interface of an advanced DSLR or mirrorless camera.

One note to enhance the usability of the Camera Pixels app: As far as I can tell, there is no built-in help content in the app itself, but there is a very useful online user guide available from the app’s developers.  You can find the user guide here: Camera Pixels app user guide.

In summary, the new Camera Pixels app is a great concept that comes closest of any camera control app I’ve found to the look-and-feel of an advanced standalone camera.  With the greatly improved new release, Camera Pixels has become the best option I’ve found for iPhone users wishing to control the phone’s built-in camera like an advanced DSLR or mirrorless standalone camera.  I now fully recommend this app, and I plan to use it as my first choice for advanced control of my iPhone’s camera.

Here’s the link to the Camera Pixels app on the Apple App Store: Camera Pixels app.
