Liam , Judy and all I have been using Aristatone copy film and it has worked fine for me. I make a 4x5 positive to a 8x10 neg I use dectol 1 to 1 dev times 3 to 5 min. For 35mm I have made 35 bw slides on direct postive using a Bowers Illumitran which was great as I could bracket and pick the slide and than enlarge it on the Arisatone. I only have a few 100 ft rolls left and I heard good old Kodak has stoped making it. Aristatone is a good and well priced. The tones for the final print are fine for my pa@pd. Liam, The problem your friend has might be is the size of the neg he is making you say striking It is a large neg how is it devleped ? I do not make large negs but I thought the agitation might be his problems.
I found a number of rolls of Kodak aerographic Direct Duplicating film 91/2 x 250 ft I have been using to make neg from my Noblex pan camera 5x14 in To me it is a large neg I had striking problems I found it was from agitation and from hand marking's from my hands I now handel the film with cotton gloves and use gentle constant agitation. It not the best film but it was very cheap in my budget and I got it to work. James Romeo

Hi James,
Thanks for your answer. My friend did buy a box of 20X24 Aristatone, but there seems to be a problem with it: it has a
very low D-max and it requires incredibly long exposure and development times to get up to D-max, which is under 2.0.
If you hold the undeveloped film up to the light, it's almost transparent. I think he was just unlucky, and another box
would be OK, but I don't think he's prepared to risk it again. He actually paid Bergger to make a batch of film just
for him in the size he wanted (several thousand pounds!), but says that a lot of it comes out streaky and he ends up
throwing most of it away. He's a professional platinum printer and is getting desperate now that he can't find a
replacement for the discontinued Agfa films.
You say you're happy with Aristatone: can you get a good, solid black on it with reasonable exposure times and a normal
development of 2-3 minutes? What developer do you use, and do you know if others are also OK?
Liam
