NO, THIS IS NOT a black-and-white photo. Nor has it been tampered with or processed. It's the result of one of my favorite photo pursuits, infrared photography. I use my Sony F707 camera with an inexpensie infrared-passthrough filter screwed onto the lens. Normally, that would produce a dark, mostly black image, because modern digitial cameras all block infrared light from reaching the sensors; this is necessary to keep infrared light from swamping the visible-light image. The Sony -- the world's first successful digital SLR with an electronic viewfinder -- also blocks infrared in normal shooting, but a special setting moves the filter out of the way when the camera's infrared beams are used as illumination at night. All that's needed for true infrared photography is to screw on the filter, switch the camera to IR Night Mode and fire away -- in daylight, of course. Infrared photos have an eerie but faint grayish green cast, and are usually much sharper than normal photos.
