    A further experiment.

    Very insufficient first development (probably too much hypo in the first developer), plus - I think - only partial fogging in the second exposure has led to extremely thin negatives with some Sabatier effect.

    In addition, the emulsion has apparently reticulated (normally almost impossible to do with modern emulsions these days); I'm guessing the bleach was too strong for this particular emulsion.

    They are probably unprintable in the darkroom, and the scans had to be heavily post-processed to produce anything

    However, liked these three ...

    Like this effect a lot! So we talking B+W film being done with C-41 chems or C-41 being done with B+W chems?

    Mark, I'm experimenting with reversal processing - which is the production of a positive transparencies (i.e. slides) from ordinary negative materials.

    In this case, I happened to be using a C41 film for a bit of fun, as I can get rolls of "Agfa" branded (but really Fuji C200) film for a £1 a roll.

    It enables me to keep the cost down while I get familiar with the manual process itself (it's a little bit of a faff, but not difficult once you have all the chems - see

    The plan is to produce transparencies from 5x4 negatives, and I've had partial success with my first attempt at that.

    I'd be surprised if I could reproduce exactly this effect a second time, as it was a result of a chapter of accidents; but it should be possible to create the Sabatier to order - after all, Man Ray and Lee Miller were all over that in the 1930s!

    Just for completeness, here's quote from Ilford's web site giving the gist of reversal:
