Response to Do films developed in PMK need cold light?

If you want to produce the very best 'fine' prints, you should use a cold light for ALL negatives. See information on 'Callier Effect' in AA books and other sources. However, if you are stuck with a condenser enlarger, PMK negs will produce superior prints. This is because approximately half the image density is made up of stain (NOT dye!) instead of silver grains and therefore will reduce substantially the Callier effect. But this is only one of countless reasons to use this extraordinary developer.
