In reply to Robert Durran:
I've always liked this one from Ansel Adams -
"There is nothing worse than a sharp image of a fuzzy concept"
I just wish I could remember it every time before I press the shutter release.
Another more general comment I heard on a photography forum. Although there is more to photography than this, I think it is very true -
Beginners think it is all about the camera.
Enthusiasts think it is all about the lens.
Photographers know it is all about the light.
