Did the fixer fog my film or did I make a mess with my first colour reversal attempt?
I've been souping my slide film in diluted C-41 chemistry at home, getting good results with fresh film and developer, but got a few nasty surprises with old developer and/or old transparencies.
My question is about some old ORWO transparencies I got cheap locally. UT-18, UT-21, UK-17 are supposed to be developed with a special process, whose components don't seem to be available nowadays. I've already tried to soup quite a few, but never got a scannable image. My last roll (UK-17, ASA40, expired decades ago) was exposed as ASA6(!), then souped in 1+100 Rodinal (yeah, that's the B&W developer I trust so far) and had decent B&W negative exposures after stopping and washing.
I put out the film, exposed it properly against the lamp and left it drying for a while in order to be spooled and colour-developed next.
After a good wash, the film was souped in diluted RA-4 chemistry. The exact dilution is unknown, but the stuff is still stinking and was able to darken the spooled film for maybe two minutes. I left it there until the frame spaces became almost invisible, but not more since I didn't want to have too dense transparencies (LOL).
After stopping in very weak citric acid, and washing for a few minutes, I bleached with C-41 bleach and the film from almost black turned orange (I had it spooled with the emulsion out to visually monitor the process).
Now comes the fun part - after pouring the fixer in (not fresh A-300 by ORWO), the film from orange turned almost black! Since the anti-haliation layer was still there after bleaching, I don't know if the bleach or the fix ruined it. Now there is almost no recognizable frame on the film, only the most over-exposed areas of the photos having a distinctive reversal image.
I did a cross-process and used the same bleach and fix a few days ago on two fresh rolls of Elitechrome 100, and got no fog at all, just great x-pro negatives, of the crazy saturation and contrast that I adore, so should I conclude that my initial B&W development was highly insufficient and that is why I got unrecognizable images at the end?
The density after the first dev was in my opinion "acceptable" as a B&W negative, but does it have to be much denser in order to be able to remove the silver slat that the second developer will "see"?
