I’ve developed colour films in black and white chemistry before especially expired C22 films with no access to that nearly extinct chemistry but I wondered if, with cheap colour films from Poundland around the corner, I might now have a cheap alternative B&W film stock.
My first run with the Poundland Agfa film saw me developing around 11 minutes in Rodinal 1+50 and it looked good despite the dark film base. Very scannable but I was doubtful it would wet print.
I went on to try and wet print a negative with my AC707 enlarger with a colour head but the results were absolutely horrible and nearly impossible to focus the negative on the board in the first place.
There’s a dog in there somewhere …
Since I hadn’t used this enlarger before i ran a quick test using a frame made using HP5 Plus and it looked OK…
Anyway, the other day there I had ordered a C41 chemistry I hadn’t used before which had instead of a developer, blix and stabiliser just developer bleach and fixer pouches and I thought, why not give bleaching a go.
I’m well aware that bleach would wipe a black and white developed negative whether colour or not but I was willing to give it a try regardless just to try and clear the base.
If you haven’t realised already, I’m bleaching already developed and fixed negatives and NOT bleaching during the developing process.
I ran a few tests and it was fine as long as you limited the bleaching to around 20 seconds, the base gets cleared but the image stays firm.
I stupidly tried to print grade 5 on the first test strip but I quickly realised I should just use white light because of the reddish base so I reset everything to 0 and tried again …
I exposed for 15 seconds at ƒ4, wide open for the Schneider Kreuznach 80mm Componon-S lens I’m using, and it looked quite good and not too contrasty.
Anyway, this was just a first run and I’m pretty sure I’ll be doing this again especially since I’ve got 14 rolls left from that bag.
I forgot to mention I’d also pushed the Agfa film to 400 by developing it for 16 minutes … I’ll probably give 800 a go some day.
Bye for now.
