I've been shooting infrared with a modified Canon 5D MKII for a couple of years now. It's really renewed my passion for shooting. When I first started shooting, it was customary to knock out a bunch of rolls of film, wait to have to get to the lab, leave it there for processing, pick it up....the whole process would at least be a few hours if not days. Infrared is the same..you shoot, the image in the LCD on the camera is magenta. You can't tell what you have until you can sit down in front of a computer for a bit.
