Is anyone open to a discussion regarding the acutance tests in Richard Henry's book along with some references to the Altman/Henn Kodak study - and how edge effects could be factored in? If PE is interested perhaps he could also help me to understand how KRL measured these things.

This would help me fill in some holes in a "discussion paper" on the relative importance of various factors contributing to the image definition.

I'm posting this here because exposure and densities are involved in knife edge tests, that sort of thing. So I'd rather put it here than in the B&W forum.

Any input from the usual suspects (Stephen, Bill B., Mr. Bill) is always appreciated.

Thanks
