I did not say Focal Point AN was unusable for 4X5, but implied how the function of potential choices
is related to other specifics, such as the degree of diffusion of the light source, the contrast level,
depth of field, and focal length relative to format. Focal Point is easy to deal with and affordable, and I certainly wouldn't want to discourage anyone from trying their product. Most often the kind of
problem I encounter with AN texture would be printing onto a very hard paper grade from a med format negative, which sometimes happens because one can't individually process each shot like in
sheet film. Raise the contrast high enough and something inevitably shows thru; and silver grain in
black and white film is more likely to interact with this effect than dye clouds in color film.
