Subject: Σχετ: Enlarger question (Vignetting)


karl, and the rest of the group.
With enlarger in our hands, I have a new question on thestign for vignetting.
(I coudl not find any guide with googling)

Si the test donw without or with a negative?
If a negative is used how dense should it be?
and I assue that the lens should be stopped down?



without a negative should work, and it's probably worth trying it at all stops. Just use thin pieces of paper for the test too, and expose for a moderate grey tone

do you have a densitometer?
