The Death of Previsualization?

Last week’s post about Yosemite’s natural firefall got me thinking about the late, great adventure and landscape photographer Galen Rowell. A topic that he wrote about often was the importance of pre-visualization in photography. That is to say, as a photographer, it is important to “pre-visualize the way the image will look on film before you take the photograph, instead of merely taking a snapshot with the naïve expectation that the outcome will be like you see.”

As I was learning the craft of photography, I always took this teaching to heart. But is the idea of pre-visualation as important today as it once was? Rowell was emphasizing the importance of understanding how each specific film type captures light and is processed into the resulting photograph.  Very few of us still shoot with film, so does the same concept hold true in the digital age?

As anyone who has learned photography with a digital camera can attest, being able to see the results of your work instantly in the field greatly accelerates the learning process. In other words, if you get the settings wrong when capturing an image, in most cases you can review the image, correct for any mistakes, and shoot again. The necessity of understanding how the camera sensor will capture the subject is diminished.  Of course, this may not hold true with certain types of action or event photography, as you might miss that critical moment.  But even with wildlife, I often take a few sample shots and review them to make sure my settings are in the ballpark of correctness.

The need for this type of pre-visualization falls apart even more when moving from DSLR to mirrorless photography. Mirrorless cameras have an electronic viewfinder, allowing the photographer to see a “live” view of exactly what the camera’s sensor sees. Here the photographer knows exactly what the image will look like before ever pressing the shutter.

So maybe Rowell’s original reasons for the need to practice pre-visualization have faded over the years. However, not all digital photographic results are directly correlated to what the photographer sees on the back of the camera. If the photographer is truly thinking digitally, they may be overexposing in order to capture more digital information in their final photo (exposing to the right). Or they may be thinking about capturing certain elements of the frame to use later in digital blending. Using techniques such as exposure blending, panorama stitching, or ISO blending all require some degree of pre-visualization of the final intended outcome.

Although the need to understand how the camera settings ultimately interact with the specific film you are using may no longer be valid for most photographers, the need to understand what you are trying to create and how to control the camera in order to achieve that vision may be more important than ever. The tools may have changed (film vs final digital output), but the concept is the same. The better you understand what you’re working with, the more predictive you can be about your desired outcome, and therefore, the better you’ll be able to prepare for that desired result in the field.

Gear I used to create the photos in this post:

On Creating Meaningful Photographs

As a photography blogger, I oftentimes get more caught up with the latest gear that was used to create a photo rather than the substance of the photograph itself. But when the focus shifts to meaningful subject matter and creativity, all pixel count, ISO performance, and frame rate melt into the background. Meaningful photographs can be created with almost any gear. In order to succeed here, the emphasis should be on photographer intent and how well the photographer conveys that intent.

Recently I welcomed the arrival of my nephew Jake with a quick photo session when he was four days old. Due in part to the latest technology of my gear, I was able to capture high quality photographs without much disruption to little Jake or his parents. I was able to use natural light, a quiet shutter, and a fast frame rate to capture those fleeting expressions of a newborn.

When I first started photographing regularly, I thought of myself as an explorer, both of the technology I was using and of the world around me. Seeing through a variety of lenses provides many different perspectives of the world, and being able to record those perspectives provides avenues of endless creativity and communication. I first had to master my tools before I could really concentrate on the art. As I improve (I like to always think of myself as improving!) I find myself thinking more about the meaning behind the pictures I am creating, and what I am trying to communicate to the viewer.

Don’t get me wrong, when taking these photos of baby Jake I was using many techniques I’ve learned over the years. But much more important than how I achieved the photos are the photos themselves. These photos will serve both as a keepsake for family members, and as a lasting record of Jake as he appeared as a newborn. I’m sure there will be tens of thousands of photos taken of Jake in his lifetime. Most will become a visual record of his life, but it is those most meaningful photos that will have lasting impact to those who love him.

The next time you are out shooting, whether you are capturing a beautiful sunset, a wild creature, or a portrait of a loved one, think about the message you are trying to convey in your image. If your answer is “I am creating a beautiful scenic”, that is a great answer. But over time, you might find a deeper message creeping into your work. I know I keep striving to find my meaning and connect with the viewers of my photographs.

Processing For Moods

Recently I uncovered a couple of unprocessed photographs in my collection that I took in Death Valley National Park several years ago. These were sitting in my “reject” pile, but upon a second look, I thought each photo had its own merit. When I looked at these two images a little more closely, I began to feel a very different mood with each.

What struck me with the first photo were the vibrant blue hues that emerged after sunset. Shot in deep twilight, the evening sky was reflected off the light tan sand, creating an amazing blue glow throughout the dune field. In order to accentuate this glow, I increased the contrast of the image overall, and increased the clarity. High contrast helped show off the intricate texture of the foreground dune, showing sharpness in each ripple of sand. Contrast was increased two ways: the first was to set the white and black point of the image. While I didn’t use the extreme ends of the histogram, I got pretty close.

The second was to add a contrast s-curve to the image. All adjustments were done in Adobe Lightroom. I kept the white balance pretty close to what the camera chose, increasing it slightly. This gave me a white balance of just over 6000 Kelvins – I was amazed at how blue it still was even after using such a warm color temperature.

The second image I selected gave me a sense of calm and quietness. In order to accentuate this mood, I kept the contrast very low. I left the white and black points where they were originally, and actually decreased the clarity, giving the dunes a soft, buttery appearance. Because this was more of a graphic image, the low clarity and contrast helped to de-focus attention on the sand texture, and instead allow the dune pattern to abstract, driving the eye up toward the distant mountains.

When making processing decisions, I find it vital to fully understand the message I am trying to convey with each photograph. These moods convey two extremes, even though the images were captured within 20 minutes of each other.

7D Mk II High ISO Performance

Last week I went out in the evening to run my new 7D Mk II through its paces with bird photography (most likely my primary use for this camera). Since my mind was in test mode, I decided to stay out after sunset (much later than normal for bird photography) to see how the camera performed in low light situations. I left the camera in auto-ISO mode to let it decide how high it needed to go. About a half hour after sunset, I was packing it in and heading back to the car, when I saw this blacktail jackrabbit eating from a patch of grass.

I was a bit skeptical that anything would turn out given how dark it was. Not even sure if the auto focus would be able to work well in the darkness, I splayed out my tripod legs and got very low to the ground. Auto-focus seemed to be tracking well, so I started firing off bursts of shots, not really paying attention to the ISO. I knew it was high, but I wanted to see how high the ISO could go and still produce a usable image. This was highly dependent on the noise produced at high ISOs, and the amount of reasonable noise reduction I could perform in post processing.

The image above was shot at ISO 25,600! While I realized this produced far too much noise for a large print, it seems to be perfectly usable for web-sized images. You can also see here that the auto-focus was extremely accurate, even in low light.

So how does this translate into changes in the way I photograph? Nothing, really – a shot with this much noise is more of a curiosity than any hard data with which to change my workflow. However, let’s look at another example at a more reasonable ISO.

I photographed this hermit thrush a little earlier in the evening than the jackrabbit. It was around sunset, but the sun had already set over the coastal mountains, so the light was certainly waning. Because of the extra light, the camera chose a more “reasonable” ISO of 5000 for this shot. But still, ISO 5000 is very high!

With my previous camera, ISO 1600 was really pushing the boundary of acceptability, with only about 50% of those images being able to hold up to the noise level. After running noise reduction on this image however, it became clear that images shot as high as 5000 ISO would be usable for many circumstances. This probably still wouldn’t hold up for a 16 x 20 inch wall print, but would most likely do fine for editorial use.

Finally, in order to show how smooth the images really are at ISO 800, I’ve included a shot of an anna’s hummingbird, followed by the 100% crop of its head.

With previous cameras, I’ve always used ISO 400 as my standard starting point, moving up and down the range as light would allow. But with the 7D Mk II, I will likely start shooting at ISO 800 most of the time. I’ve run a slight amount of NR on the hummingbird shot, but the noise is so low that I’d rather have an extra stop of light to play with and get faster shutter speeds than feel the need to drop down to a lower ISO.
