So far I've bought all Ilford chemicals and paper and just went by the instructions. It's worked great for the negs, they've all turned out good. I've got 8x10 trays for paper, but I would have to come up with something else if I want to do bigger prints. I did buy a set of Ilford variable contrast fiters. I learned I needed those by making some really bad half-assed contact prints with a piece of scratchy plastic and the room light! Ha! Whoops... I guess the Jobo might make sense since it takes up less space. Hmmm... Is it more work to get one of those contraptions running compared to trays? I don't know anything about them. I like the trays in that there's nothing mechanical to break, no electronics or anything, just dump in the chemicals and go. But I don't know if I've got room for big trays, I'd have to rig something up in the bathtub perhaps.
So...is there like a universal thread for these enlarger lenses or do I need some kind of plate or mounting doodad specific to the enlarger? Also does anyone happen to know what the little sliding bit is on the lens? There's this knurled slider thing but as far as I can tell it doesn't actually do anything? I noticed some other lens also have it. At first I thought it might be a lock for the aperture but the rings still moves regardless.
Excellent shot!Ansel Adams would be pleased.
I can't speak for the aging of Kodak papers, but I imagine that it is similar to ILFORD papers in that respect. ILFORD papers are considered to have a 3 year shelf life from the date of manufacture. As the paper ages, it will tend to show several effects; at first, there will be a loss of contrast. Secondly (usually coinciding with the contrast loss) there will be a speed loss. Last, there will be a buildup of fog. Once the paper starts showing some fog, it is IMO useless (some people would advocate anti-fogging agents, but for me, my time in the darkroom is too precious to waste with anything other than good quality). The contrast and speed issues are of little concern with a VC paper, since you can make adjustments as needed. However, I would be hesitant to give such product to a beginner, just in case there is any problem that they might not notice (where an experienced printer would).David CarperILFORD Technical Service
