First post on APUG! I am looking to get in to film acceleration, for which I hear the Ektachrome 200 film is best, or maybe Fuji 400. Unfortunately, I only have some older Astia 100 lying around. I am hoping to get at least E.I. 5,000 out of it. . . Is this realistic at 40 min. at 75° Fahr. (24°C)? Also, I note that the C-41 bleach is not optimal, rather the ferricyanide/bromide variety is better for "optimal" results. Does anyone know if the 8- & 12g or 30- and 10g varieties of ferricyanide & bromide bleach, respectively, per liter, are better for this purpose?
