Thank you--this is the clearest I've seen angle and distance described yet :) I drag out Dr. Geep's tutorial on lights every time I have to fiddle with lights, but it contains SO MUCH dense information that it gives me a headache to find, figure out and apply the info. I think I need to find just the tutorial by itself, with no forum participation, redownload it and print it on better quality paper, too. (Please note that this is not true of his other tutorials, just this one! And just for me, probably)
