I would submit that unless you are technical, documentary photographer (ie, a medical or scientific photographer for the most part), then every photographer is an artist to a greater or lesser degree. They may not always think about it, but I'm willing to bet that most people using a camera whether consciously or un, apply some degree of personal approach to taking a photograph.
Yes. Just by picking up a camera and deciding to take a picture can be an act of creating.
Not so much a Marcel Duchampian type thing.
But just thinking of taking a picture of a building.
The building was designed by someone. It could have been designed as a piece of art or architecture.
We might really like a portion of it and take a picture. So we are taking a picture of the pre-existing art that is already there.
Same with taking a picture of a dancer or an athlete (like gymnastics or cheer).
The choreographer has already created the dance. The athlete has implemented that art and probably added a bit of themselves to it as well.
Us as a photographer are capturing that art. And then . . . we may add our own little angle to it as well.
It can be a masterful step, just recognizing the art that is already in front of us!
Take care & Happy Shooting!
