If you’re looking for a way to transform an ordinary “snapshot” into something more interesting, sometimes all you need is a longer exposure. If you’re able to travel with a small tripod, you can really get interesting shots with just a little practice and a few accessories. Continue reading
I had the chance to play around with an infrared DSLR while teaching a workshop in Virginia. I’ve never used IR before, and I’m glad that the “IR Queen,” Deborah Sandidge was there to show me the ropes.
In the past, IR photography was something most people really didn’t do. Options for IR before digital came along were to either use IR-sensitive film or an IR cut filter on the lens. Neither of these options were particularly ideal. IR sensitive film was a real pain because it had to be kept cold and had to be loaded in complete darkness to avoid clouding it. IR cut filters, which only allow infrared wavelengths to pass, make shooting tough because they block all visible light… meaning you can’t see through the camera with one attached to your lens. Moreover, exposures with IR filters needed to be on the order of minutes to capture anything.
With digital, the game has changed. You can send your old DSLR or even a point and shoot camera in to a company and have the optical low-pass filter removed and replaced with one that blocks most visible light. Depending on your ambitions, there are several “flavors” of conversions, including some that allow certain visible wavelengths to pass through in addition to the IR ones. Once you’ve converted your camera, you’ll need to explore the art of processing IR images. Continue reading
Part of the art of photography is visualizing your shot through the camera viewfinder (or LCD panel). When you’re in the field, you tend to scrutinize your subject. After all, you want the subject placed in the frame properly, you want to focus precisely, and more. Unfortunately, this often leads to “tunnel vision.” Your mind subconsciously blacks out the other elements of the frame, especially the corners and background. Continue reading
