Re: curves and gum and Christopher James book
Yves, Since I've never done PDN and never expect to do it, I don't SERIOUSLY care whether you're blowing air or revealing truths. Tho I admit being intrigued. HOWEVER, if you're so smart (and I could believe that you are) you shouldn't be able to blow us off with just those phrases and titles we don't understand.
Your assignment, should you accept it, is to put those statements into terms a gum printer, or the equivalent, could follow. I would bet real money (say a beer) that not one university professor outside the math department in 50 would know what "linearized tone mapping" means, and just the phrase, "adaptive logarithmic mapping" could clear a college classroom in seconds.
Which is to say, since you know so much, state these concepts in words, not jargon.
....looking forward to enlightment on a flatter gradient,

Christina, I find it very strange that a University professor finds that linearized tone mapping is hitech when it's in fact the worst approach one can use. It is as if you never eard of Tone mapping operators (Adaptive logarithmic mapping (F. Drago, 2003), Dynamic range reduction inspired by photoreceptor physiology (E.
