I have been a musician and composer all my adult life. I can tell you that almost without exception, composition is the greater "art". It is certainly more challenging. It is often more rewarding. (I do not wish to take anything from the art of the performer, I have been that as well.)
In terms of photography, I usually "perform" every aspect entirely on my own. So, by your definition I might be an artist. Sometimes, with colour work, a lab will do the work which follows the button... sometimes under my supervision, if it is a challenging project, or sometimes autonomously, when they can easily achieve the results they know I expect. I have a fine working relationship with my lab and trust them to print something right. They are well rewarded for this. Does this make me less of an artist?
This is the first time I have been so personally offended on APUG (as much because you misunderstand the musical arts as well as the photographic) that I had to actually step away from the computer before I responded. I can only say, Denise, with all due respect, that you are mistaken.
