I was never good at art, I can't paint, or draw, or do sculptures. I have to work at the artistic side of photography but I'd like to think I am getting there, though I always flinch when someone refers to me as an artist!
would be more acceptable ... sort of.
There are teacherss of art who might claim that much of the skill of 'art' creation can be learned by something like technical means, given some basic hand and eye co-ordination ability. However it takes time and practice.
The vision associated with creativity, on the other hand, is likely independent of the mechanics of art creation as understood historically. It is quite possible, especially with a camera bit with more generally accepted 'artistic' activities too, to be reasonably technically proficient in creating a 'piece of work' but not necessarily one that is especially creative (or appealling) in any respect.
Mostly, I think, the way one's braion is 'wired' seems to be the promiry influencing factor. Very variable it seems - which is probably a good thing more often than it is not so good. Perhaps.
