Hello all - after all the wonderful help I received fom this group with a previous problem, I thought I'd try you with another. I am looking for something to reduce negative density i.e., to reduce the thickness of the emulsion layer on sheet film.

I have tried jewellers rouge on the end of a cotton bud and with lighter fluid as a medium, but have had no luck. It just seems to polish the emulsion (after prolonged rubbing) without really removing any of the gelatin layer - it just seems too fine. I tried metal polish, too, with marginally better results: it bites into the emulsion, but I have to polish for such a long time and with such a force that I lose control over the area of emulsion which I am trying to reduce.

I have also tried a very sharp exacto knife, but instead of "shaving off" very thin layers it just removes all the emulsion right down to the film base or it leaves darker "stress" marks.

The reason I am trying to this? To subtly retouch/remove small blemishes/cliche verre.

Many thanks,
Neil.
