>>Is the 31-step wedge, mentioned, on a 4x5 piece of substrate? I was
thinking sandwiching this in front of film, in my film holder, and
exposing in-camera would also serve to help me conduct film tests...
BTW, anyone use this method of generating film curves and finding
film speeds? I'm assuming that I would be exposing an evenly
illuminated
surface at zone X? (snip)<<
This method is described in John P. Schaeffer's "Ansel Adams Guide:
Basic Techniques of Photography- Book 2" pp. 52-61.
I've used it and found it to be very efficient and convenient.
