I believe Chris was talking about a thread where "folks can go and get some form of tutorial as to "F-stop" settings, blade angle, photo-shop tricks of the trade. "ISO" settings and other various "helpful hints" to get more members (and non members) in the game" specifically to help folks take better knife images.
I remember that thread. It was more about having a place to post photos mostly of things other than knives and very little technical information.
Rick,
Quite obviously you didn't read read through the thread very well.

Links to some of the exact same things you are talking about and there was a lot more.
