If you are consistent with that logic then a slide or transparency is not a
photograph unless printed on silver halide photographic paper.
And it's not. The process is photography, but the result is properly called a slide and not a photograph. If you look at the Agfa contest rules, you'll see they don't take slides either. And I didn't complain, I'm not into the business of trying to pass slides as photographs.
