Haven't used it in many years, but recently saw some beautiful NATURAL results from another photographer and decided to upgrade my version 3 Pro to version 6 pro, and the $29 for the upgrade seems to be well worth it, especially for interior shots, since I've been taking them for my friends when they decided to sell their homes. I took a series of 5 bracketed 1 stop exposures in continuous mode. I'm not sure I should have had the lamps on, but I put 25 watt bulbs in them to keep the shades from burning out. I like the perspective corrections in Photomatix. (The camera was on a tripod.)
