Hi

I have to ask what the difference between enlarging paper and paper for contact printing (AZO, etc.) is. As a 35 mm user I use enlarging paper for all my work. Is there difference in sensitivity, tonality or what?¨

Any links to earlier threads are welcome.

Greetings Morten

Azo is reeaaallly slow, and, unless you're using the new head that was designed to be powerful enough to enlarge with Azo. For contact printing, you'll need to use a separate light bulb, or take out the lens and lensboard from your enlarger and blast away with light. I tried enlarging at home, and got no image on Azo even with a five-minute exposure time. I watched Michael Smith enlarge my negatives at his place, and have lovely prints as evidence of the head's usefulness.

I've tested the new production run of Grade 3 Azo (much slower than the new Grade 2), and have exposure times of about 45 seconds under either my Saunders LPL or Beseler MX enlargers out of which I've taken the lens and lensboard. That said, as a contact printing paper it is gorgeous stuff, and I have yet to develop it at home in Michael Smith's Amidol formula, which "those in the know" tout as the best stuff for the job.

Galerie and Forte Elegance can come close to Azo, and have the advantage of being usable for enlargements, but they're not quite as luminous. Azo's worth a try for anyone interested in contact printing on silver paper. Note that you will have to change your negative development time to use it best - longer for Grade 2, and in my case shorter for Grade 3.
