Pro Techniques

Jim Karageorge has been an eyewitness to the changing face of corporate photography over the years. “Today, the stories that corporate clients want to tell are different from those we told in the past,” Karageorge, a corporate/industrial photographer, observes. “They are geared more toward the human factor than the technologies.”

There are many kinds of white light. At first this statement seems like it doesn’t make sense, but if you look closely at a typical light bulb in your living room (the old kind, not the new florescent type of bulbs) and compare it with, say, a daylight florescent fixture, the light bulb is much more yellow than the florescent light. Similarly, if you compare sunrise and sunset lighting to the light from an overcast sky at noon, the lighting from low angled sunlight is very yellow—it looks golden, in fact—and the cloudy sky produces a white light that is more bluish.

“I usually try to make the scene look and feel as natural as possible while still augmenting the available light,” Canadian-born photographer Peter Leverman observes. “I want the viewer to see the image and get what I’m trying to put across without the technique getting in the way.” By extension, Leverman knows when to leave well enough alone and simply use the existing lighting, in contrast to some photographers who prefer to noticeably overwhelm the scene with their lights.

When it comes to subjects that combine color and light in creative and interesting ways, few things are as eye-catching or as fun to encounter as an artfully designed neon sign. If I’m out driving on a summer’s night and see a particularly interesting bit of neon, it’s hard not to pull the car over just to admire the sign maker’s skill and take a few pictures to add to my collection.

When Yiming Hu was a freshman in college he rented a camera and fell in love with photography. After he moved from China to the United States he was drawn to landscape and travel photography and learned advanced photo techniques from books, magazines, the Internet, and lots of experience. Today he works as a computer engineering professor at the University of Cincinnati doing research, and as a second career he shoots landscapes and travel subjects in many locations to satisfy his photo appetite. I spoke with him recently about his work.

HDR stands for High Dynamic Range. What this refers to is the digital sensor’s ability (or lack of ability) to render good detail in both the highlights and the shadows in a photograph. Our eye/brain combination is extremely sophisticated, and as we look at a contrasty scene (such as a landscape in noon sunlight) the detail in the shadows and in the bright sunny areas is quite clear to us. A photograph will not look the same as we see it.
