Re: Developing Color in B/W Reversal Chemistry

Yes, it appears to be a B/W reversal kit that uses potassium permanganate "Blix" a/k/a Bleach.

I'm surprised there is no sodium sulfite clearing bath used after bleaching. I would think the "Blix" would leave something of a purple stain, but perhaps not.

At any rate, a finished print too light can be attributed to a variety of causes:

1. Film overexposed.
2. First development too long or temp. too hot.
3. Re-exposure after bleaching insufficient (you cannot overexpose at this point).
4. Second development too short or temp. too cold.

hope this helps,

Ed

As far as I'm aware the celer-reverser kit is b&w chemistry.

>Has anyone had any experience of developing Plus-X 7265 (super 8 b&w reversal) with the celer-reverser kit? 
Per the original question above; please note that one cannot develop b & w film in color chemistry because bleach in color processing removes the silver, leaving the color dye-based image behind. If the image is silver-based--as it is in b/w--then no image will be left.
