    I think it falls under "potential bibliography".

    If this is true, Mr King would you be sure to keep us posted on when the book would be available. I'm sure I'd like to have a copy.

    Well, that too but more importantly I am just trying to get an idea of the kinds of ideas that have been proposed. I am trying to write something on this but I don't want to reinvent the wheel if there is already a better wheel out there than the one I have in mind.

    In Barry Thornton's book "The Edge of Darkness" (P41-48) he describes testing camera focus accuracy using a board with a series of 1cm spaced vertical lines drawn on it. The center line is marked and is the point of focus. Distance is 2 feet from the board and all cameras had full aperture.

    Upon developing the film he has several photos showing how far off the focus is for each camera tested. I thought it was an interesting test and I am going to try it. It does involve using rolls of film, developing and printing etc.

    I hope this helps.
