That wasn't the one I was thinking of Doug, but it was good to go back and read through that thread. I'm afraid the one I wanted may have hit the bit-bucket when the Photo-Art forum was cleaned up.
I'm pretty sure it was either roger_ele or Bill M who posted it - and it would have been in the past 2 (maybe 3) months, but I can't find it by searching through any of their posts. It was an actual list of things that an eye is drawn to and away from in a photo. I remember there being about 8 items on the list, but the only three I can remember are light/dark, focus/out-of-focus, saturated/unsaturated.
FYI - It would have only been deleted had the thread been in the self-service mini-challenge forum which was pruned in preparation for the makeover to the new format. - Danny
