I have a lot of footage from Sony cameras where the blacks are at about 20 and the whites are at 255. I would like an "auto" way to get the blacks to 16 and the whites to 235 for general footage with a high dynamic range.
Using AutoGain(adjust_mode=1,dark_exclude=0.00,bright_exclude=0.00) as suggested previously, the blacks come out at about 16, which is where I want them, but I can't find a setting to roll the whites off to 235. The highlights remain at or close to 255 so they clip and a little detail is lost. Is there a setting that can roll off the white to 235 or should I look at a different filter? This is probably similar to what PDyksma and Dogway were asking, but I want to be sure.
