>> I use a "gamma" of 1.8, so you can factor that into your perspective. << Me too, unless I know from the start it's going to VHS only, in which case I go linear (1.0) because that's what my gamma screen looks best at via composite out of my PAR or Targa+. I remember seeing you post this formula a while back… I understand very little of it, mainly because I'm not sure of all of the terms indicated by the letters, and just general video term ignorance. <g> >> Gamma correction does affect the "apparent" brightness of an image but does not increase the brightness. Instead, it would seem that the apparent brightness is due to a desaturation of the darker and lighter pixel values, rather than actually increasing the luminance bandwidth. This is an important point as it has a direct bearing on whether the formula works with gamma corrected pixel values. << This is very interesting! >> And hopefully soon I'll be able to find some more time to write a program which will make it a little easier to use. << Great! When you have even more time <g>, I really think you should write a book, or several chapters at least, in which you cover 3DS and video. It seems to me to be one of the major areas of 3DS training which has been overlooked. I'm sure there are a lot of people like me with no formal training in video, who are currently working on industrial level projects, trying to cope with NTSC peculiarities. Thanks, as always, for the info. By the way, I just received Bones Pro yesterday. I can see why you were so excited about Smooth. A *very* nice tool to have! Paul S.
