I started out as a Fisher Price Toy Camera Pretender, then I became a Poloroid Puller, then I graduated to be a Film Exposurist, then I transitioned to a 3 Megapixel Digital Snap-Shooter, then I became a Novice Photography Wannabe, and now I am an Amateur Photographer.
I think the use of Picture Taker vs. Photographer for the feature story is just a means to discuss art. I don't take is seriously, and I don't call anybody on this forum a "picture taker". Everybody here is a photographer of some degree. Novice, experienced amateur, seasoned-pro, etc.
I guess if all you are doing is selfies for Face-book then you are a picture-taker. I dunno. I draw stick-figures, but I don't call myself an artist when I do.
This is not a topic that will keep me up at night. I sure miss my Fisher Price toy camera. I played with it until the color wheel peeled and it didn't work well any longer, and then I asked for another one. I wonder if it is still at the house.
