Hello!
Here's the steps from a Kodak publication for reversal processing
(1973): (supplied with Kodak Reversal Processing Kit)
1. First developer D-67 6-8 Mins. (68 F)
2. Rinse Water 2-5
3. Bleach Bleaching Bath R-9 1
4. Clear Clearing Bath CB-1 2
5. Rredevelopment Fogging Developer FD-72 8
6. Rinse Water or SB-1 Stop Bath 1
7. Fix Kodak F-5 or F-6 5
8. Wash Water 2
And here's the formulas:
D-67
Water at 125 F 500ml
Elon 2.0 gr
Sodium Sulfite (Anhydr) 50.0 gr
Hydroquinone 8.0 gr
Sodium Carbonate (mono) 52.5 gr
Potassium Bromide (anhydr) 5.0 gr
Sodium Thiocyanate (liquid)
51% solution 3 ml
Water to make 1.0 liter
OR
D-19 1.0 liter
Sodium Thiocyanate (liquid)
51% solution 3 ml
Replenisher D-67R
Water (125 F) 750 ml
Elon 2.0 gr
Sodium Sulfite (anhydr) 90.0 gr
Hydroquinone 8.0 gr
Sodium Carbonate (mono) 52.5 gr
Sodium Thiocyanate (liquid) 51% Sol. 7.5 ml
Water to make l.0 liter
FD-72
Part A
EASTMAN Sodium Dithionite (sodium 5.0 gr
hydrosulfite (Cat No. P533)
Part B
Water 500 ml
Balanced Alkali 10.0 gr
EASTMAN L-(+)-Cysteine 0.3 gr
Hydrochloride (Cat No. 2367)
Water to make 1l0 liter
Disolve 5 grams of Part A in 1 liter of Part B not more
than 2 hours before use. Discard after one use.
Bleach Bath R-9
Water 1.0 liter
Potassium Dichromate 9.5 gr
(anhydr)
Sulfuric Acid (concentrated) 12.0 ml
CAUTION: Add acid to solution slowly, stirring constantly.
Clearing Bath CB-1
Water 1.0 liter
Sodium Sulfite (anhydr.) 90.0 gr
SB-1, F-5 and F-6 are well known formulas.
The films listed are the discontinued Direct Positive, Panatomic-X,
also discontinued, Plus-x and Tri-x Reversal films, discontinued as well.
And 4-X reversal 7277, something unknown to me.
I'll bet the EASTMAN chemicals, which were some sort of special bulk
order at the time are no longer available from Kodak; I don't really know.
They may be available from Bryant Labs in Berkeley, Aircraft or other
chemical supply houses.
Probably best to use the older type black and film and not the T-Max.
Experiment at your own risk.
