First, I collaborate with the model and the image appears. It's adjusted, cropped, manipulated, dropped.... picked up, changed again, twisted, toned, and finally posted.
Then comes the second part: the viewer's reaction to the image. Some like it, some don't care. Some pretend to be experts, some just pull a bunch of crap out of their asses. Very few actually give an intelligent and constructive critique.
I still can't figure out which part of the art process is more interesting :)
