I'm developing my b&w-film since years now without a single problem - but sheet film drives me insane!
I've acquired a Jobo 2830 because it takes two sheets and is affordable (Jobo Expert in Germany is now 500$+ and takes 330ml of chemical with an uneven number of sheets!).
I only handled the film with gloves, used demineralized water, 250ml of fluid, lowest concentration (in my case 1+14) to avoid fast development reaction and rotate the drum on a leveled base with approx. 30min-1 and a turn in direction every 30s.
The most critical moment seems to be the first tilting when the developer slowly enters the drum - it takes me at least 5s to tilt the drum and make a first revolution - too long?
Also the edges don't seem to be properly developed (brownish) - despite good film position within the drum.
I've read in older posts that people use the Jobo 2830 without a problem!?
Any advice? Alternative process?
