I think its a mixture as well. I think everything can be taught if a person is willing and able to learn. However, I think some people are born predisposed to pick things up faster than others, whether its because they learn motor skills faster, or problem solve faster or whatever. Its a little subjective when we start talking about "Art" as well as "skills". Art doesn't really have a concrete definition. It can be anything to anyone in a sense. One mans art is another mans garbage. Skills you can learn. As Keith stated, there is a technical side and a formula to many things ( not just photography ) that can be learned and performed. There are many people shooting school portraits that just do the same mundane formula day in and day out. There is no artistic creativity going on, but they are making money and doing what they like in a field that is often considered "Artistic". Also, if you want to really dig down to the nuts and bolts of things, in a sense, many of us are just copying what others have done. I mean who was the first person to selectively color? Is anyone else using that technique less creative or artistic because they didn't come up with it first? I guess how you apply techniques and ideas to shots is where your artistic side comes into play, but then again, that's only if its received as art by the viewer. So now you have two variables, not only do you have to attempt to be creative and find your only reasoning or method to your madness, whoever is the viewer ultimately has the end say in whether you are a "genius" or a "hack". So perhaps most of it is based on you figuring out what your viewer will see as artistic or creative. Even if to someone else its not . Case in point, I can do some gaudy overbaked HDR shot and show it to my co-workers and they will think I am a god among men, however, if I showed it on this thread, I would be considered a hack. So really there is no answer to this question since there is no concrete answer as to what "artistic" even is.
