I know that the "GAMMA" topic maibe out of "fashion" on ASOFT but I need to straighten out some "?" to "!". I think I got somewhat a grip on it but just want to make sure I got It right! It's about the 4 settings of gamma in the gamma dialoge. They are as follows : Display gamma : 1.3 ( These values are added just to make ) Framebuffer gamma : 2.2 ( the discussion ) Input file gamma : 2.0 Output file gamma : 2.0 Questions : 1. If I render to the framebuffer and to to disk, wich of the Framebuffer or Output file gamma is used when calculating gamma at 48bit color space? It should be the Output file gamma! But what happens to the picture on screen? Will it be gamma corrected at 24 bit space when displayd or the same as outputfile gamma or not at all? 2. Is input file gamma used ONLY when the bitmap-format you load doesn't have any gamma value? Is it then degammacorrected set by inputgamma and then gamma corrected at 24bit accordingly to the frambuffer or display gamma? 3. If I want to network render annimations with different output file gamma, do I have to change the gamma value in the 3DS.SET file on every mashine? For every entry!!!! It doesn't seam to be saved in the projectfile?! Maybe wishlist <g>! -M.E
