Interesting discussion on pros vs entusiasts (let's not call ourselves amateurs).
Pros do get an undeserved amount of criticism.
Mostly, I think it's based on envy from enthusiasts who would like to be pros. But couldn't or wouldn't make it.
Today, everyone thinks they're photographers and don't appreciate the skill that is required.
Even if a lot of pro work may seem derivative, it actually takes a lot of skill to deliver the shots that the client wants. They don't have the luxury to shoot whatever they like however they like.
i think the pros keep photography alive as an respected artform, even if they can't always produce art.
