Further paper surface tests.
Just last night I finally got a bit of darkroom set up in the garage. All I wanted to do was anything and I thought I would see what the Foma/Arista.edu ultra "semi-matte" surface is like.
At this very moment I have a Kodak Photographic Papers book from the fifties open to Kodabromide N. With the Arista, I don't think you can get any more similar without the real thing. I had some paper scraps in the paper safe from 1999 that I think ARE the real thing, a polycontrast II Rapid on N. Emphasis on "I think." If I am correct, they are virtually indestinguishable.
Tonight I hope to see what the Forte Matte and Varycon "Matt" are like.
I am also going to weigh a sheet, 11 x 14, of each on the Ohaus. Man, that Arista is some kind of anorexic thin. I don't think I've ever seen such a thin paper, or so it seems.
I know none of this has anything to do with image characteristics.
Oh yeah, the weird thing about the Arista "semi-matte" is that the Foma equivalent - allegedly - is called matte. No way. It has a definite sheen and if "semi-matte" isn't right, I'd say "smooth luster." Which just happens to be what Kodak has called the N surface from time to time, although they tend to go with "semi-matte" as they are nowadays with color print paper.
More tomorrow.
Look, it's not even tomorrow on the east coast, the envelope, please......
All papers are RC, nominally white base.
I weighed a sheet of 11x14 of each paper I recently purchased, plus extrapolated a 5x7 of Kodak Polycontrast II. Yes, I found the writing on the back that says Kodak and I know by era what I was using.
Arista.edu Ultra/Foma 22.2 grams
Forte Polygrade V RC 25.7
Kodak Polycontrast II 25.9
Varycon VC RC 29.0
So truly, the Arista/Foma is the underweight fashion model of the paper world.
The Varycon had a totally different feel right out of the envelope. Sort of limp, more like ordinary paper. It was hard to tell the emulsion side from the other. Little would I guess what came later.
I then put a piece of each paper right into the fixer and, uh, fixed it and dried. Again, the Varycon was very different. It took much longer to dry with the hair dryer, maybe 3:1 over the others. It was very limp, but then dried became very three dimensional. Wow, I'm thinking, this is fiber based. I looked at the envelope, and it did say "double weight matt." I've never heard that term for RC paper, but the weight per above is certainly more than other papers. I checked now on Freestyle and it definitely says RC. Is it possible that it is PE on one side only? I'm at a loss to explain this.
As to surface finish, the Kodak is, of course, N "semi-matte." As said previously, the Arista/Foma is a virtual dead ringer, although under the blue box Foma, they call it "matte." The Varycon is matte by my definition, as they claim. The Forte is also a ringer for the Kodak N, yet they call it "matte."
As for whiteness, here are some shocks. The whitest, absolutely, was the Arista/Foma. In second place was the weird Varycon. Oddly, though claiming no whiteners IIRC, the emulsion side is whiter than the back. Howz dat?
Third place went to the 1980's Kodak Polycontrast II. At that age, I'm not expecting anything. The most off white, as you've guessed by now, went to the Forte, although not much worse than the ancient Kodak. I even ran this one twice. Folded over, the paper base is whiter than the emulsion side. Dud paper? Too old? I might take up Freestyle on their generous returns policy.
Summary:
1. Weights do vary considerably. Some combination of paper and the poly layer. Claims of so many grams per square meter do not include the poly and the emulsion, I presume.
2. There is a lot of real world variation with descriptions of matte and semi-matte. I don't understand why marketing can't call finishes what they are. Even Arista/Foma can't get their acts together.
3. Varycon is one weird paper. Did they put fiber base into my RC envelope?
4. Forte came up even, um, creamier than my ancient Polycontrast. Wazzup?
5. Mostly, don't trust catalog/manufacturer's descriptions!
Next, actual printing of negatives! Wow, what a concept.
