Emigrant Lake Reflection (Photo of the week)

This week’s photo comes from a backpacking trip I did this summer with a friend. Emigrant Wilderness is a backpacker’s gem, especially once you get out of range of day hikers. Easily accessible from the San Francisco Bay Area, it is often overlooked due to Yosemite’s popularity. Once in the southern part of the wilderness which borders Yosemite’s northern boundary, it is not uncommon to go days without seeing another person.

This morning we had gotten up early and were on the trail by 6:30. We had situated our camp so that we would cross Emigrant Lake’s northern side just as the rising sun was cutting across the water at a low angle, bathing the southern mountains in beautiful light, and giving me a nice reflection in the lake. The lush grass along the shore was a bonus – the long shadows across the grass give a real sense of early morning stillness.

Here are some other shots from the same trip:

Pre-visualizing the shot

You’ll often hear professional photographers talking about “pre-visualizing” the photos that you want to take. Abstractly, this makes sense – instead of going out for the day and just snapping what you see (many people can now do this with their phone cameras that they have with them all the time), you think about specific photos that you want to capture, and then go about creating them. Sounds great, but how does it actually work?

With landscape photography, if you don’t pre-visualize a photo that you want to create, you’ll end up driving around all day looking out the window of your car until you happen to get lucky – being in the right place at the right time. This can work well for you, especially if you have unlimited money for gas and many years to spend driving around! Let’s put this into practice. Let’s say I want to capture a shot of the sun reflecting across the ocean. I live in California, so that means sunset. Looking at a calendar will give me the exact time to be there. Now I have my time, but what about place? Do I want cliffs dropping into the ocean with the sun lighting them? Do I want a wide beach with waves? Do I want the smooth water of a bay or inlet? Do I want strong foreground elements like smooth boulders or footprints in sand, or jagged rocks jutting out of the sea? First I answer these questions, and then do some research. Obviously the internet is a great tool for finding reference shots of specific places, but topographical maps or applications like Google Earth can help immensely.

Here is a shot in which pre-visualizing the photograph that I wanted played an essential role in the success of the photo. It was a dark, overcast, winter day and the wind had picked up. Definitely the kind of day that you cozy up by the fire with a good book. I wanted to create a photograph to capture how I was feeling – something moody, black and white, and dramatic. Kerry and I decided to head to the coast and enjoy the cold and solitude. Half way into our walk I saw a subject that perfectly communicated what I was feeling – a bent over lonely tree on a sea cliff, struggling against the wind.

I knew when I took the picture that I was only part of the way to my imagined image. The rest would come in post-processing by converting to black and white, adjusting the levels to really silhouette the tree, and burning the edges of the photo to accentuate the drama of the incoming storm. The result conveyed everything I thought about before I left home. Sometimes it is great fun to head out with a camera and no expectations of what I will find – often times I am happily surprised. But for anyone intent on improving their photographic skill and taking a large number of successful photos, pre-visualization is an important component.

To HDR or not to HDR

Sometimes capturing a scene that has very bright and very dark areas with a camera can be impossible, because both film and the digital sensor can resolve fewer stops of light than the human eye. Traditionally, this limitation was overcome by using a graduated neutral density filter, which darkened the bright portions of the scene to allow the film to expose the entire scene correctly. With the advent of digital technology, there has been a trend to move instead to post processing and digital manipulation to achieve similar results.

HDR (or High Dynamic Range for the uninitiated) has been sweeping the digital photography world for the past couple of years, mostly thanks to some new software that makes creating these images easy. The goal is simple: use several shots of the same scene at varying exposures to create a single image with a greater dynamic range (the range between pure white and pure black) than your camera can capture. Unfortunately, this goal is usually not achieved with results that look correct to the human eye. The final images appear flat and with low contrast, and the colors tend look almost cartoonish. This can be overcome to some degree by increasing the black level and overall contrast – however correcting the color issue is difficult.

The solution is to go back to digital basics. Instead of letting software automatically combine 3 or more shots at different exposures, combine 2 or more images yourself in an application such as Adobe Photoshop using stacked layers and various blending techniques. Photographer Glenn Randall covers some of these techniques and the principals behind them in his recent article for Outdoor Photographer magazine. The images below demonstrate using image blending verses an HDR software approach.

The above image was created by blending three photographs of different exposures together using software. Once this was done, the contrast was increased significantly. However, as you can see, the colors still look unnatural, with too much yellow in the rock. In addition the two rock faces in the background are washed out.

The image below combines two the the images used to create the previous image. The foreground and mountain were exposed with no evaluative metering compensation. The sky was exposed in a second shot at -1 stop, and blended into the foreground using a graduated mask. The result is more natural looking.

Some people like the aesthetic of HDR images, and that is great. It brings a new artistic flair to the world of digital photography. But since I am usually trying to create a final photograph that accurately portrays what I see in nature, using the blended approach often works better for me.
