I know a lot of art photographers who use old processes. They aren't making forgeries or attempting to make photos that someone would be fooled into thinking was old.

A funny thing was I was talking with a well-known print (ink) artist who does digital collages. I was surprised at how little he knew about digital printing itself-- how to identify laser versus inkjet printing under the microscope, halftone reproductions, blacklight and paper, etc. He just bought a big printer and used it. I also met a photographer from Paris who was having an exhibition, and she said she sent her photos in to be developed by a company. She likely wasn't up to date on a lot of stuff collectors know. So an expert can know more about the physicality of the artwork than the artist him or herself.
