What constitutes a photograph as "GREAT" ??? random thoughts for a journal entry...

Ive come to the realization that a great photograph doesn't always need to be lit artificially, nor do you need to have extraordinary models doing extravagant things. Its more of the mood (for me) and what you are trying to confront the viewer with, if you can do this and some how relate the viewer to that photograph in a way that makes them think (maybe about themselves or others), you did your job...In my opinion, jus sayin...
