Jean-David, The human eye doesn't process the film, it looks at the processed film. It doesn't process the paper; it looks at it. It doesn't project the light that falls on the subject and can't physically effect it directly. The reality of the hard side of the image creation is what many don't know about; real limits built into the physical elements. I know Bob could see all these things happening. The ability to see the colors doesn't always translate into knowing how to do something with them.
