whait a minute. what about tone mapping?
The response curve produced by tone mapping is different from the GC curve. They have some similar characteristics but they're not the same.
By analogy, if you were to go into Photoshop "Levels" and set the midpoint at 40% versus 30%, you get similar but different response curves.
Tone mapping does increase the luminance of dark colors. But the luminance of the darkest 20% are not increased enough by tone mapping. No exponent value you choose will ever produce the same brightening as GC does.
So we basically have the same problem as ever - we are forced to add more light to bring the apparent illumination to something closer to correct. At least, however, tone mapping doesn't blow the highlights. It can't - it can never produce a luminance of 1.0 or higher.
thanks. i respect all what you do for us. and i dont want to be like a guy who is complaining or bashing.
but will SM realese some info how to get 100% ambient with tone mapping without making it brighter? i a lot of times use texture maps with ambient set to 1. with tone mapping it changes all the time. i tryed out every setting and even yours. but its never the same.
