Purple Mountain’s Majesty [Encore Publication]: Including mountains in your images

Whether we’re traveling halfway around the world or just a few miles from home, we travel photographers get excited about including mountains in our images.  Mountainous landscapes can provide so many of the most basic elements we look for in a great photograph: beautiful light, compelling composition, exquisite textures, and an authentic sense of place.  In this post we will cover some of the fundamental techniques for capturing great images of mountains.

As with most kinds of photography, it all begins with beautiful light.  Whenever possible, try to shoot mountain landscapes near sunrise or sunset, or when something interesting is happening with the weather conditions.  The quality of light tends to be best during these times.  You’re more likely to capture lovely colors on the peaks and in the sky, and the image is more apt to give a sense of depth and drama than during the middle hours of the day.

Shooting from the deck at our lodge in Torres del Paine National Park in Chile, I had to miss most of an excellent dinner to capture Lago Grey with its mountains and glaciers during the “golden hour” just before sunset.  The lovely interplay of colors and textures, from the sky to the peaks and to the icebergs and water, made the resulting image worth the effort.  Buy this photo

When shooting mountain landscapes, it is usually a good idea to bracket your exposure.  With the camera fixed on a sturdy tripod, compose your scene and then shoot a series of images, each with a slightly different exposure.  Many cameras have settings to automate the process of bracketing.  The two main benefits of exposure bracketing are raising the odds you’ll have a perfectly exposed image and allowing you to create a high dynamic range (HDR) image from several different exposures.  See this post for a refresher on how to use exposure bracketing: Post on Exposure Bracketing.

This HDR image of Yosemite National Park’s peaks reflected in the Merced River was created from a series of different exposures made using bracketing.  The camera was mounted on a tripod and I made a series of seven shots, each one exposed 2/3 of a stop brighter than the previous one.  Buy this photo

I’m often asked how to make mountain images that really “pop”.  Why are some photographs of mountain landscapes so dynamic and compelling, with intriguing contrast between the peaks and the sky?  Of course, there are many elements that go into the making of an excellent image, but there is a “secret sauce” that can dramatically improve many mountain images: the polarizing filter.  Properly using a circular polarizing filter on your lens can emphasize the contrasting parts of the rock, snow, and/or ice on the mountains and can also add drama to the clouds and sky.  Every image shown in this post was made with a polarizer.  Be sure to adjust the filter by turning its outer ring until you see the effect you want to achieve.  Usually this involves rotating the filter’s ring until you see the maximum polarizing effect possible and then dialing it back a little (or a lot) until you achieve a balance between added drama and a natural look.  Experience helps here.  Check out this post on the use of filters, including polarizers: Post on Filters.

This image of a rare lenticular cloud forming on the summit of Osorno Volcano in Argentinian Patagonia was made using a polarizing filter to bring out the cloud formation and darken the sky.  Buy this photo

Mountain colors can be glorious, but also consider converting some mountain images to black-and-white during post-processing.  Rendering in black-and-white can emphasize the textures on the crags and peaks of a mountain and can also lend drama to the foreground and sky.  Shots captured with a polarizing filter will usually result in more intriguing monochrome images.  When converting to black-and-white during post-processing, be sure to play around with the contrast and individual color channel sliders until you achieve the result you want.  For more info on black-and-white photography, check out this post: Post on Black and White Photography.

This shot of a rock dome in Yosemite’s Tuolumne Meadows area is striking when rendered in black-and-white.  Buy this photo

Sometimes when we’re traveling we don’t have the option of returning to a gorgeous mountain location when the lighting is perfect.  Don’t let the flat lighting of a bright mid-day sun stop you from shooting the local peaks.  Great images can be made at any time of day.  Just make sure to follow the main techniques outlined in this post: compose well, use a polarizing filter, and bracket your exposure.

Patagonian peaks captured on our way out of Torres del Paine National Park.  Because we didn’t have the option of returning at the golden hour, I made this image in the harsh mid-day sun.  With careful attention to composition and the use of a polarizing filter and exposure bracketing, I was able to make a favorite image in spite of the less than perfect lighting conditions.  Buy this photo

Will Photography Soon Be Obsolete? [Encore Publicaton]: Musings on AI as artist

A friend recently pondered via a social media post whether we will have photography as we know it in the future, or if artificial intelligence (AI) will soon generate all of our images.  With tens of millions of people now capturing snapshots on their phones’ cameras and instantly applying AI-generated filters to enhance or modify the images, we can certainly observe an increasing trend toward computer involvement in the making of photos.  But I don’t believe AI will replace the artist’s eye in the making of fine-art photographs for quite some time to come.  Here are a few semi-random musings on this theme.

A machine can certainly generate bad art.  In college in the mid-1980s, I wrote a program for my Computer Science final exam that composed musical canons (pieces in which each voice plays the same melody together, but starting at different times).  My code used a semi-random configuration of musical intervals as the opening melody, then applied a simplified set of the rules of counterpoint (how musical lines are allowed to fit together) to complete the canon.  I received an “A” for this project, but truth to tell, any listener familiar with classical music could instantly discern that the pieces composed by my program weren’t anything like the lovely canons written by Telemann, for example.  In other words, my AI didn’t pass the Turing Test.

In the more than 30 years since I wrote that program, AI has progressed by leaps and bounds.  Computers can now generate poetry, classical and jazz music, and even paintings that many non-experts judge as products of human artistic creativity.  I’m fascinated by the progress, but so far the best of the AI-generated “art” is really just imitation and trickery: it takes a seed of something original such as a photograph or a melody, and transforms it using a set of complex rules that could be described as a pre-programmed artistic style into something pleasant enough but not inspiring.

In his landmark 1979 book, “Gödel, Escher, Bach: An Eternal Golden Braid,” Douglas Hofstadter amazed the world by demonstrating comparable interlocking themes of grace and elegance among the very different disciplines of mathematics, visual art, and music.  He even speculated on the ability of machines to create works of great insight.  But Hofstadter’s proposed approach differed from that of the AI field that has developed since then in that he favored teaching machines to create via an understanding of how the human mind creates, as opposed to today’s AI approach of taking mountains of data and throwing brute force calculations at it.  To my eye, ear, and mind, this brute force method is the reason most of today’s attempts to artificially emulate the creative process are not insightful and do not add anything to their genres.  And so far, the vast majority of these attempts fail their respective Turing Tests.  That is, humans can tell it is a machine and not a human generating the “art.”

Applying these musings to the art of photography, what do see today?  To be sure, more images are being generated today than ever before in human history, and the art of photography is being devalued by its sheer pervasiveness.  Everyone captures images now, and most of them believe that makes them photographers.  While photographers have always required the involvement of a machine in the creation of their art, good photographers have always relied on their artistic vision, the so-called artist’s eye, to create images that are special.  I don’t believe that all the Meitu and similar AI filters that abound today are creating any photographic art that adds insight or helps interpret the world around us.

One very central component in photography is composition.  How does the photographer choose what elements to include in the image, and how will these elements be combined?  Read my recent post on composition here: Post on Composition.  This vital aspect of photography does use some “rules”, such as the Rule of Thirds, Leading Lines, Framing Elements, Point of View, Foreground/Background, and Symmetry and Patterns.  Rules, of course, can be programmed into an AI so that the machine can emulate the way humans create.  But in photographic composition, the “rules” are really just guidelines for getting started.  A good photographer knows when to break the rules for artistic impact.

Even the dumbest devices are capable of generating images.  Security cameras can capture images that we would consider to be rudimentary documentary photographs.  Given long enough, a security camera might accidentally capture what we would consider to be a good street photography image, because after capturing millions of dull scenes, sooner or later the camera will catch a random alignment of interesting elements.  It’s like thousands of monkeys typing random characters: given enough time, one of them will coincidentally type out a Shakespeare sonnet or even a full play.  As wearable computing devices become more pervasive, many people’s lives will be documented in real-time via the capture of millions of images.  Some of these may be interesting to their friends and perhaps the general public.  A few may even have artistic value.  But true artistry isn’t characterized by coincidence.

I don’t doubt that eventually we will get to the point where machines can create images as good as much of what humans can create.  I think we’ll get there, but it will take a long, long time.  And in the meantime, the role of photographer as artist, experimenter, and interpreter of the world around us will continue to be central to our society’s need for communication and expression.

What do you think about the future of photography?  Will we soon see machines creating much of our imagery?  How about our good, artistic imagery?  Please share your thoughts here.

I don’t doubt that eventually we will get to the point where machines can create images as good as much of what humans can create.  I think we’ll get there, but it will take a long, long time.  And in the meantime, the role of photographer as artist, experimenter, and interpreter of the world around us will continue to be central to our society’s need for communication and expression.

What do you think about the future of photography?  Will we soon see machines creating much of our imagery?  How about our good, artistic imagery?  Please share your thoughts here.

Purple Mountain’s Majesty [Encore Publication]: Including mountains in your images

Whether we’re traveling halfway around the world or just a few miles from home, we travel photographers get excited about including mountains in our images.  Mountainous landscapes can provide so many of the most basic elements we look for in a great photograph: beautiful light, compelling composition, exquisite textures, and an authentic sense of place.  In this post we will cover some of the fundamental techniques for capturing great images of mountains.

As with most kinds of photography, it all begins with beautiful light.  Whenever possible, try to shoot mountain landscapes near sunrise or sunset, or when something interesting is happening with the weather conditions.  The quality of light tends to be best during these times.  You’re more likely to capture lovely colors on the peaks and in the sky, and the image is more apt to give a sense of depth and drama than during the middle hours of the day.

Shooting from the deck at our lodge in Torres del Paine National Park in Chile, I had to miss most of an excellent dinner to capture Lago Grey with its mountains and glaciers during the “golden hour” just before sunset.  The lovely interplay of colors and textures, from the sky to the peaks and to the icebergs and water, made the resulting image worth the effort.  Buy this photo

When shooting mountain landscapes, it is usually a good idea to bracket your exposure.  With the camera fixed on a sturdy tripod, compose your scene and then shoot a series of images, each with a slightly different exposure.  Many cameras have settings to automate the process of bracketing.  The two main benefits of exposure bracketing are raising the odds you’ll have a perfectly exposed image and allowing you to create a high dynamic range (HDR) image from several different exposures.  See this post for a refresher on how to use exposure bracketing: Post on Exposure Bracketing.

This HDR image of Yosemite National Park’s peaks reflected in the Merced River was created from a series of different exposures made using bracketing.  The camera was mounted on a tripod and I made a series of seven shots, each one exposed 2/3 of a stop brighter than the previous one.  Buy this photo

I’m often asked how to make mountain images that really “pop”.  Why are some photographs of mountain landscapes so dynamic and compelling, with intriguing contrast between the peaks and the sky?  Of course, there are many elements that go into the making of an excellent image, but there is a “secret sauce” that can dramatically improve many mountain images: the polarizing filter.  Properly using a circular polarizing filter on your lens can emphasize the contrasting parts of the rock, snow, and/or ice on the mountains and can also add drama to the clouds and sky.  Every image shown in this post was made with a polarizer.  Be sure to adjust the filter by turning its outer ring until you see the effect you want to achieve.  Usually this involves rotating the filter’s ring until you see the maximum polarizing effect possible and then dialing it back a little (or a lot) until you achieve a balance between added drama and a natural look.  Experience helps here.  Check out this post on the use of filters, including polarizers: Post on Filters.

This image of a rare lenticular cloud forming on the summit of Osorno Volcano in Argentinian Patagonia was made using a polarizing filter to bring out the cloud formation and darken the sky.  Buy this photo

Mountain colors can be glorious, but also consider converting some mountain images to black-and-white during post-processing.  Rendering in black-and-white can emphasize the textures on the crags and peaks of a mountain and can also lend drama to the foreground and sky.  Shots captured with a polarizing filter will usually result in more intriguing monochrome images.  When converting to black-and-white during post-processing, be sure to play around with the contrast and individual color channel sliders until you achieve the result you want.  For more info on black-and-white photography, check out this post: Post on Black and White Photography.

This shot of a rock dome in Yosemite’s Tuolumne Meadows area is striking when rendered in black-and-white.  Buy this photo

Sometimes when we’re traveling we don’t have the option of returning to a gorgeous mountain location when the lighting is perfect.  Don’t let the flat lighting of a bright mid-day sun stop you from shooting the local peaks.  Great images can be made at any time of day.  Just make sure to follow the main techniques outlined in this post: compose well, use a polarizing filter, and bracket your exposure.

Patagonian peaks captured on our way out of Torres del Paine National Park.  Because we didn’t have the option of returning at the golden hour, I made this image in the harsh mid-day sun.  With careful attention to composition and the use of a polarizing filter and exposure bracketing, I was able to make a favorite image in spite of the less than perfect lighting conditions.  Buy this photo

Will Photography Soon Be Obsolete? [Encore Publicaton]: Musings on AI as artist

A friend recently pondered via a social media post whether we will have photography as we know it in the future, or if artificial intelligence (AI) will soon generate all of our images.  With tens of millions of people now capturing snapshots on their phones’ cameras and instantly applying AI-generated filters to enhance or modify the images, we can certainly observe an increasing trend toward computer involvement in the making of photos.  But I don’t believe AI will replace the artist’s eye in the making of fine-art photographs for quite some time to come.  Here are a few semi-random musings on this theme.

A machine can certainly generate bad art.  In college in the mid-1980s, I wrote a program for my Computer Science final exam that composed musical canons (pieces in which each voice plays the same melody together, but starting at different times).  My code used a semi-random configuration of musical intervals as the opening melody, then applied a simplified set of the rules of counterpoint (how musical lines are allowed to fit together) to complete the canon.  I received an “A” for this project, but truth to tell, any listener familiar with classical music could instantly discern that the pieces composed by my program weren’t anything like the lovely canons written by Telemann, for example.  In other words, my AI didn’t pass the Turing Test.

In the more than 30 years since I wrote that program, AI has progressed by leaps and bounds.  Computers can now generate poetry, classical and jazz music, and even paintings that many non-experts judge as products of human artistic creativity.  I’m fascinated by the progress, but so far the best of the AI-generated “art” is really just imitation and trickery: it takes a seed of something original such as a photograph or a melody, and transforms it using a set of complex rules that could be described as a pre-programmed artistic style into something pleasant enough but not inspiring.

In his landmark 1979 book, “Gödel, Escher, Bach: An Eternal Golden Braid,” Douglas Hofstadter amazed the world by demonstrating comparable interlocking themes of grace and elegance among the very different disciplines of mathematics, visual art, and music.  He even speculated on the ability of machines to create works of great insight.  But Hofstadter’s proposed approach differed from that of the AI field that has developed since then in that he favored teaching machines to create via an understanding of how the human mind creates, as opposed to today’s AI approach of taking mountains of data and throwing brute force calculations at it.  To my eye, ear, and mind, this brute force method is the reason most of today’s attempts to artificially emulate the creative process are not insightful and do not add anything to their genres.  And so far, the vast majority of these attempts fail their respective Turing Tests.  That is, humans can tell it is a machine and not a human generating the “art.”

Applying these musings to the art of photography, what do see today?  To be sure, more images are being generated today than ever before in human history, and the art of photography is being devalued by its sheer pervasiveness.  Everyone captures images now, and most of them believe that makes them photographers.  While photographers have always required the involvement of a machine in the creation of their art, good photographers have always relied on their artistic vision, the so-called artist’s eye, to create images that are special.  I don’t believe that all the Meitu and similar AI filters that abound today are creating any photographic art that adds insight or helps interpret the world around us.

One very central component in photography is composition.  How does the photographer choose what elements to include in the image, and how will these elements be combined?  Read my recent post on composition here: Post on Composition.  This vital aspect of photography does use some “rules”, such as the Rule of Thirds, Leading Lines, Framing Elements, Point of View, Foreground/Background, and Symmetry and Patterns.  Rules, of course, can be programmed into an AI so that the machine can emulate the way humans create.  But in photographic composition, the “rules” are really just guidelines for getting started.  A good photographer knows when to break the rules for artistic impact.

Applying these musings to the art of photography, what do see today?  To be sure, more images are being generated today than ever before in human history, and the art of photography is being devalued by its sheer pervasiveness.  Everyone captures images now, and most of them believe that makes them photographers.  While photographers have always required the involvement of a machine in the creation of their art, good photographers have always relied on their artistic vision, the so-called artist’s eye, to create images that are special.  I don’t believe that all the Meitu and similar AI filters that abound today are creating any photographic art that adds insight or helps interpret the world around us.

One very central component in photography is composition.  How does the photographer choose what elements to include in the image, and how will these elements be combined?  I haven’t written a post in this space yet that specifically covers the topic of composition, but it’s on my list to write and publish soon.  This vital aspect of photography does use some “rules”, such as the Rule of Thirds, Leading Lines, Framing Elements, Point of View, Foreground/Background, and Symmetry and Patterns.  Rules, of course, can be programmed into an AI so that the machine can emulate the way humans create.  But in photographic composition, the “rules” are really just guidelines for getting started.  A good photographer knows when to break the rules for artistic impact.

Even the dumbest devices are capable of generating images.  Security cameras can capture images that we would consider to be rudimentary documentary photographs.  Given long enough, a security camera might accidentally capture what we would consider to be a good street photography image, because after capturing millions of dull scenes, sooner or later the camera will catch a random alignment of interesting elements.  It’s like thousands of monkeys typing random characters: given enough time, one of them will coincidentally type out a Shakespeare sonnet or even a full play.  As wearable computing devices become more pervasive, many people’s lives will be documented in real-time via the capture of millions of images.  Some of these may be interesting to their friends and perhaps the general public.  A few may even have artistic value.  But true artistry isn’t characterized by coincidence.

I don’t doubt that eventually we will get to the point where machines can create images as good as much of what humans can create.  I think we’ll get there, but it will take a long, long time.  And in the meantime, the role of photographer as artist, experimenter, and interpreter of the world around us will continue to be central to our society’s need for communication and expression.

What do you think about the future of photography?  Will we soon see machines creating much of our imagery?  How about our good, artistic imagery?  Please share your thoughts here.

 

Purple Mountain’s Majesty [Encore Publication]: Including mountains in your images

Whether we’re traveling halfway around the world or just a few miles from home, we travel photographers get excited about including mountains in our images.  Mountainous landscapes can provide so many of the most basic elements we look for in a great photograph: beautiful light, compelling composition, exquisite textures, and an authentic sense of place.  In this post we will cover some of the fundamental techniques for capturing great images of mountains.

As with most kinds of photography, it all begins with beautiful light.  Whenever possible, try to shoot mountain landscapes near sunrise or sunset, or when something interesting is happening with the weather conditions.  The quality of light tends to be best during these times.  You’re more likely to capture lovely colors on the peaks and in the sky, and the image is more apt to give a sense of depth and drama than during the middle hours of the day.

Shooting from the deck at our lodge in Torres del Paine National Park in Chile, I had to miss most of an excellent dinner to capture Lago Grey with its mountains and glaciers during the “golden hour” just before sunset.  The lovely interplay of colors and textures, from the sky to the peaks and to the icebergs and water, made the resulting image worth the effort.  Buy this photo

When shooting mountain landscapes, it is usually a good idea to bracket your exposure.  With the camera fixed on a sturdy tripod, compose your scene and then shoot a series of images, each with a slightly different exposure.  Many cameras have settings to automate the process of bracketing.  The two main benefits of exposure bracketing are raising the odds you’ll have a perfectly exposed image and allowing you to create a high dynamic range (HDR) image from several different exposures.  See this post for a refresher on how to use exposure bracketing: Post on Exposure Bracketing.

This HDR image of Yosemite National Park’s peaks reflected in the Merced River was created from a series of different exposures made using bracketing.  The camera was mounted on a tripod and I made a series of seven shots, each one exposed 2/3 of a stop brighter than the previous one.  Buy this photo

I’m often asked how to make mountain images that really “pop”.  Why are some photographs of mountain landscapes so dynamic and compelling, with intriguing contrast between the peaks and the sky?  Of course, there are many elements that go into the making of an excellent image, but there is a “secret sauce” that can dramatically improve many mountain images: the polarizing filter.  Properly using a circular polarizing filter on your lens can emphasize the contrasting parts of the rock, snow, and/or ice on the mountains and can also add drama to the clouds and sky.  Every image shown in this post was made with a polarizer.  Be sure to adjust the filter by turning its outer ring until you see the effect you want to achieve.  Usually this involves rotating the filter’s ring until you see the maximum polarizing effect possible and then dialing it back a little (or a lot) until you achieve a balance between added drama and a natural look.  Experience helps here.  Check out this post on the use of filters, including polarizers: Post on Filters.

This image of a rare lenticular cloud forming on the summit of Osorno Volcano in Argentinian Patagonia was made using a polarizing filter to bring out the cloud formation and darken the sky.  Buy this photo

Mountain colors can be glorious, but also consider converting some mountain images to black-and-white during post-processing.  Rendering in black-and-white can emphasize the textures on the crags and peaks of a mountain and can also lend drama to the foreground and sky.  Shots captured with a polarizing filter will usually result in more intriguing monochrome images.  When converting to black-and-white during post-processing, be sure to play around with the contrast and individual color channel sliders until you achieve the result you want.  For more info on black-and-white photography, check out this post: Post on Black and White Photography.

This shot of a rock dome in Yosemite’s Tuolumne Meadows area is striking when rendered in black-and-white.  Buy this photo

Sometimes when we’re traveling we don’t have the option of returning to a gorgeous mountain location when the lighting is perfect.  Don’t let the flat lighting of a bright mid-day sun stop you from shooting the local peaks.  Great images can be made at any time of day.  Just make sure to follow the main techniques outlined in this post: compose well, use a polarizing filter, and bracket your exposure.

Patagonian peaks captured on our way out of Torres del Paine National Park.  Because we didn’t have the option of returning at the golden hour, I made this image in the harsh mid-day sun.  With careful attention to composition and the use of a polarizing filter and exposure bracketing, I was able to make a favorite image in spite of the less than perfect lighting conditions.  Buy this photo
