Well I foolishly thought that I'd just look this up on the web and go, but oddly haven't had much luck in English or Russian! I've got two rolls (thus little latitude for experimentation) of 120 Svema fn-64 (Ukrainian) that I must've bought there ca. 1999-2001. I think it was stored room temperature for some years, frozen some others - it sort of got out of my possession for a while, then came back... It's marked develop time 8 mins in soviet standard developer (#2). Expiry 2002. So if this were something equivalent like Ilford or Kodak with similar speed, age and history, I'd probably shoot at a half or full stop less and process normally or a little longer. Found nothing on the massive developing chart for HC-110 (will submit if I have any luck). I did see some references to D-76 and others, and will develop based on those as compared to other D-76 vs. HC-110 I'm out of Ilford so figured I'd shoot one of these. Industrial landscapes. Ideally I'd get something decently printable that I can put into the same set of photos as my 'good' film (in-date and recent Ilfords). Anyway, all I've got available handily is HC-110 (and I seem to have an ~10-year old unopened bottle of T-max developer), so asking advice if anyone has any on this... To tell the truth, I'm not so knowledgeable on the differences between developers as I am also a cheapskate and use the HC-110 as supplied in the darkroom I work in (university) at various dilutions. If there's a compelling reason to use a specific developer instead of these, let me know that too - I'd hate to 'waste' this old film!
