Bleaching Fuji instant Fp 100 negative

[hpulley]

First, rumors that FP-100B has been discontinued... now ScrubbingBubbles with Bleach? It's a conspiracy I say!

Does this bleaching process work with the larger Fuji 4x5 film like FP-100c45?
Thank you!

Absolutely

Right - You do want the emulsion side down, and well protected. The various drain cleaners with sodium hypochlorite work very well and are easier to use, I found.

The quality of the result can be good. Here is a large-ish file. The "grain" texture is pleasing, and good sharpness. Look around the girl's eyes.

[QUOTE=Marco B;1002568]You may be glad nothing happened, probably due to the fact you had the emulsion side down while applying the bleach, as per the instruction of the link you posted. If you had used a ferricyanide bleach on your images, your FP100B BW negatives would have gone almost transparent, as ferricyanide turns the silver of BW negative into an almost colourless silverferri/ferrocyanide complex. Ferricyanide bleach is a first step for a two bath sepia toning kit.

I have had my inspiration by Bobs weblog as well. When I introduced it to my tacher and classmates they were enthousistic about it. I decided to make a small blog about it. There are various ways to do this process. This is my way wich works for me very well:

Taping is too much trouble. This is MUCH easier...

[Peter de Groot]

Cool. The bleach won't get underneath without the tape? Hmmm I will give it a try. I take it is essential to wet the emaulsionside to let it stick to the glass. Thanks for the tip.

[ChristopherCoy]

Not if your careful. FP100C is pretty tough. To date I've done about 40 negatives using the "wet" method above, and haven't had an issue.

[Peter de Groot]

Works like a charm. I got 6 negatives drying right now!
