I'm building a DR and have the opportunity to place 2 of the same enlarger side by side. I'm looking for reasons why this would be useful. I have 1 example of a dual enlarger set up, i.e. results from Bruce Barnbaum, his cover page of Tone Poems ~ Book 2. http://www.barnbaum.com/tone2.html I discussed this with Bruce at his workshop.
Is there another compelling reason to have a 2nd enlarger? (besides parts, I'm the only one using the space) I guess I could set one for 35mm or 120mm diffuser box and the other for 4x5. I'm a non-pro, and do not have all the techniques understood..Masking etc? Do advanced techniques require a 2nd enlarger or make the process much easier?
