Hi Bob and Ken,
thanks for your replies.
So clearly this effect is predominately related to the grain size. If the
grains were sufficiently small (or even non existent), then I assume this
effect would not be seen at all. I know it probably seemed that my question
had an obvious answer, but I somehow got the impression from an APUGian's
answer that the effect wasn't related to the grain.
So does anyone have some hard numbers ? e.g. if I use a fine grained film
such as PanF with a low accutance developer, what size enlargement (when
viewed from a 'typical' set distance) would I begin to see differences in
the tonal smoothness between the 35mm neg print and say a 4x5 neg print.
(note I see this question as being different to the common question: "at
what size enlargement could I begin to see the grain in the 35mm neg's print
when viewed from a 'typical' set distance")
regards
Peter
