Re: curves and gum and Christopher James book
Yves, A couple things. In your post: I find it very strange that a University professor finds that linearized
You are critiquing my role as a University professor, which I don't take kindly, and yes, I was offended (as if you couldn't tell). So many thanks for the apology.> 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.

Oh, and yes, BTW, I have never EVER EVERRRRR heard of tone mapping operators. Unabashedly.
My father was a consultant metallurgist physicist and wrote the book on stainless steel and fractology as well as a book disproving Einstein's special theory of relativity, yet he ran a boy scout troop for 30 years with the motto that if you can't explain Einstein to a boy scout you don't know what you are talking about. He also raised us 8 kids to believe that motto and I love him for it (God rest his soul, he's been dead since 94). He is directly responsible for why I am in photography today--his laboratory was in the basement of our house (large house) and I would tinker with chemistry and such with him as well as expose and develop macro fractology prints in the darkroom within the laboratory, which photographs he used in legal testimony to prove who was at fault when a coke bottle blew out someone's eye, for instance. As an 8 year old, mind you. And I understood!
So when you come out in an email with all this mighty speak above, it makes my head spin, and it tells me more about you than it does about your point, and it does not make your point more palatable which is, I think, your original goal--to spread "correct" information to the masses of the uneducated--apparently us.
My original point of my post was exactly this: there are many ways to skin a cat. Tony Gonzalez does amazing prints. He has two in the book. His curve looks like caca. But the proof is in the pudding. Dan Burkolder (if I am smart enough to get this correct) does linearized curves. His prints are gorgeous and he displays all over. For my litttle pea brain and my students' little pea brains Burkholder and Nelson's systems are as high tech as I can teach and want to teach--it is NOT a digital class, it is an alt class. But I guarantee you that the digital professor in my department would also consider Burkholder and Nelson "high tech". (BTW David Hatton, do you know your curve is also in James' book??!!)
I guess, since the proof is in the pudding, I don't agree that linearized curve systems are not the right way to go. The great thing about teaching is that over the course of a semester you get 300 prints per class to prove otherwise. I would suggest that you translate the information you think is correct to a usable system/program, and then let some alt listers use it on negs and then you will have practical proof whether it works. I will gladly volunteer--perhaps I can send you an image, you can do your magic to it, send it back and I will print? If the proof is in the pudding, you need alt prints to prove it, and I am sure there are those like myself on the list that will help with that. I did download the article (12pp) and will read sometime after spring break. So thanks for the original message even if your way of saying it bordered on rude, and let's get this going.
