Smashing Magazines got a great little Photography post.

"A camera does not work like an eye; film does not work like memory. There is a fine line between a photo that is quite nice and one that is quite breathtaking. At some unknown point, a photo can cross the Rubicon and be forever a piece of beautiful art. That hinterland between a regular photo and evocative art is a shifting area from person to person and taste to taste. However, that zone can be narrowed a bit once you start to consider the way the brain stores memories and emotions.
And yes, it gets a bit touchy-feely here trying to determine if your work has crossed that line. With rigorous practice and peer feedback, you can start to appreciate where that zone is and, consequently, improve your hit ratio."
