efke 25 ort & efke 50
i want to try these films, but i wasn't able to find exaustive information like reciprocy failure or development curves. do you have any info? also personal experience is wellcome.
good film. I've used it quite a bit and like it for long exposures.
I know what I want but I just don't know how to go about gettin' it.-Hendrix
Single layer type emulsions. Pretty soft so develop with extra care.
Best fit with high acutance type developers like: Rodinal, Beutler, FX-1, Neofin Blau.
Do not over develop and certainly not over expose (pull) Efke films. The Efke 25 and 50 are Orthopan films. In fact you can develop them by sight under X-ray (very dark red) light.
I use the Efke 25 for landscape photograpy, Beutler A+B 1+1+10 7:00 minutes at 20C.
Great results. If I want an iso 100 version of Orthopan I am using the new Rollei Retro 100 TONAL film.
