You absolutely have to shoot off a tripod. Use manual exposure. Focus manually with the R72 filter off the lens. The auto exposure modes seem to get confused, so use manual exposure mode. I use auto white balance as well. I convert to BW in the channels mixer, using mainly the red channel. I sometimes push the green and blue channels up to 7 or 8 percent. I won a Detroit News photo contest with one of my IR pics. It's here: http://www.photo.net/photodb/photo?photo_id=4235460 On Sep 17, 2006, at 3:24 PM, David J Brooks wrote:
