What is reversal processing?

I'm a student so please forgive me if this sounds ignorant.

I noticed that on the inside of Kodak TMAX 100 film boxes, there

is a short line mentioning "reversal processing".

What is that? How can we do that?

Reversal Processing is the process required to obtain slides from a

film. The basic steps are:

1) development with a strong developer (e.g. paper developer)with some

silver solvent (e.g. rhodanid)

2) bleaching the developed silver with Chromium (VI) Oxide

3) clearing, removing the residues of the bleach

4) reversal exposure to a strong light source - OR - chemical reversal

5) development with a strong developer

6) fixing

<p>

Washing between each step, takes about 1 hour total. Kodak and tetenal

(Germany) both sell chemical kits for reversal, the price per film is

roughly 3 Pfunds Sterling.

Save your time and effort and use Agfa Scala and the commercial Scala

process.

For more information look at the Kodak site.

Yes Kodak makes a kit and I have used it extensively in the past. Don't

know much about the Tetenal that Wolf speaks of. The slides are

beautiful. Rate your TMX at ASA50 and the Kodak is a 6 step process. A

bit time consuming and a tad expensive but the results are nice.

Hello Scott,

<p>

what kind of bleach is Kodak using? The old Tetenal Kit used

Chromoxid, the new one permanganate, which seems to be more of a mess.

By replenishing the bleach I reduce the enviromental hazards. (Finally

the bleach will be cut with alcohol to reduce remaining Cr VI to Cr

III which then will be taken by disposal service as "heavy metals".)

I think it is permanganate also if they haven't changed it recently.

They have changed their C-41 and RA's so I couldn't tell you. Sorry.

Cheers
