I got an IR filter for Christmas and did some experimentation. I think I've finally got down the how to take pictures, but I'm still working on the processing part. These are two shots I took of a 45-ft waterfall at the Krohn Conservatory in Cincinnati, OH. 25 mm lens, f/25, 4 sec exposure in visible and 4 min exposure in IR. I'm curious as to what people think, especially if there are suggestions on how to process the IR shot better. Oh yeah, and anyone have an idea as to why the water disappears in the IR?
