Old Film Types
By any chance, does anyone know which of these Eastman Kodak films, if any, resembles HP5 400 the most?
Super Speed Portrait
Portrait Panchromatic Panatomic
Par Speed Portrait
By resembles, I mean, in terms of similar development temp/time for a certain developer. Or, in other words, for a particular developer, I know the temp/time for each of these films. I want to extrapolate to HP5.
None these are all low speed films and don't resemble HP5 in any way.
Maybe my response was too hasty, Rodinal 1+100 1 hour stand agitation for the first minute and that's it for the next 59 minutes. The examplest you've posted are from the 1930's I personaly love the look of SS-panachromatic. Super sensitive pan used to be a motion picture film that could be used for still photography. So you could try Kodak D96 (Homemade) or D76 (original formula). If you are after the look of films from the 1930'S lucky SHD 100 and 400 can give you that look so can Polypan F. To recreate the period look read Roger Hicks and Christopher Nisperos Hollywood Portrait. It's not the film that created those images but lighting and retouching.
Thanx very much for the info.
Actually, I have about 8lbs of Amidol I'm trying to use. I found some Amidol film formulas and want to try it on HP5 which, I'm heavily invested in. The article gives the time/temp for the above flims. I was just trying to establish a correlation as a basis from which to start my own tests on HP5. Just trying to burn through as little film as possible so, starting point would have been helpful. OH well.
Clip testing would be my advice then. Found this developer online Pyrodol Amidol+Pyro and the inventor uses HP5+
