Digital Formats

Find the "right" format for you

It’s interesting to me as an observer of digital photography’s evolution that few people seem to discuss formats. I’m talking about digital formats based on the size of the sensor. In film, we used to talk about formats all the time: 35mm, 645, 6x6, 6x7, 4x5 and so on. Each of these formats has advantages and disadvantages for the nature photographer.

After Sunset

Nature photographers shooting digital can capture striking scenes after the sun has gone below the horizon

If you haven’t tried shooting after sunset with a digital camera, you might think this is absurd. This fall, I was doing a workshop in Moab, Utah, and after the light had gone from the fall-colored cottonwood in a low area of Arches National Park, some of the group wanted to keep going and head up to Balanced Rock, which wasn’t far away.

Digital Exposure

What does good exposure give you? And can you trust the histogram?

Auto-exposure systems built into cameras today are very good. Camera manufacturers have done an outstanding job in creating complete systems that give excellent results. The computing power inside a camera equals powerful stand-alone computers of not that long ago. Multiple metering points are measured at the instant of exposure, evaluated, compared to a database of what a good exposure should be for the conditions and an exposure is computed and sent to the camera controls to execute in terms of ƒ-stop and shutter speed—all within that same instant.

The Rashomon Effect

Our perceptions of equipment strongly influence how we feel about it

Photographers love to argue about their gear. Are you a Canon shooter or a Nikon shooter? Maybe you have an affinity for Olympus or Pentax cameras. Or perhaps you love the technology companies and have something from Panasonic, Samsung or Sony.

HD Digital Video

The world of high-definition video offers new opportunities for nature photographers

Many outdoor photographers have long admired nature documentaries like those from the Discovery Channel and National Geographic. Yet when they tried shooting in traditional video, the results were often disappointing. Video wasn’t known for its detail and color rendition.

Spot Be Gone

Cloning is an important tool for nature photographers. Here are some tips for using it.

spot be goneThis past summer, I saw the late-afternoon landscape reproduced here. I loved the light, the contrast of the river and its green trees with the dry landscape around it. Unfortunately, no matter what I did, I couldn’t get rid of some spots of flare that appeared when I used a graduated filter (split ND). Without the filter, no spots. With the filter, spots.
