I thought that my Garage was huge when I built it, but the 30x44' space seems cramped when I set up my temporary studio in it. In order to get good separation between subject, camera, lights and backgrounds I using up about 2 1/2 bays so the cars get 'kicked out' when the 'Studio' is up. This year I had success with low key portraits using a single Photogenics 1200 with a 36x24" softbox placed about 7' out and 2-3ft left from the subject and about 8 ft high. A single reflector for fill. and my second Photogenics with a snout used as a hair light. This was evenly lighting the subject area for F5.6 and dropped off enough so the background some 11 ft. behind was 2-3 stops lower. Auto white balance on the 1dMkII seemed to have some trouble varying about 1000K from shot to shot.This kind of variation didn't seem too bad until I took a few white balance shots using an Expodisc synced the rest of the images in Adobe Lightroom which made all the difference. Gotta start using this thing more!
