I saw that question posted on an art forum, and found it rather interesting. I was surprised by the amount of people that do not think photographers are also artists. There were more than a few that viewed photographers as people that merely push a button on a camera and capture a scene. That seems to be a rather limited view of photography. Maybe it is because photography is accessible to pretty much anyone that can whip out a smartphone to take a picture. But, there is a big difference between the average person taking a selfie and a professional photographer. Most professional photographers that I talk to put a lot of time into composing their image, learning their craft, setting up their shot, creating their scene, etc
Part of why I found the question interesting is because I do both art and photography. I do them for very different reasons and the process is different, but they both satisfy my creative desires. The end results are basically the same. I create pictures that I hope people enjoy, that evoke emotion, that are decorative, etc. To me it is art.
