It seems there are different settings for various papers and enlargers. I remember Omega says to set 100M for Kodak VC grade #3. But it is 55M for Ilford grade #3 with a Saunders 4550 enlarger. Am I missing something?
no, but keep in mind that here is an ISO standard for paper grades but no standard for filter numbers.an ISO grade 3 and a number 3 filter have little in common. it is best to calibrate your color enlarger to the standard ISO grades ala Paul Butzi's method or mine.You'll find the former on the web and get the latter fupon emailrequest to email@example.com
