B&W Film Reversal

Permanganate Bleach Solution

Mix equal parts A and B before use. Mixture will last a short time so it is stored in equal parts before use.

Part A

• 4g Potassium Permanganate

• 1000ml Water

Part B

• 54.5g Sodium Bisulphate

• 1000ml Water

For films with weaker emulsions such as HP5 and Kentmere 100 the quantity of the Potassium Permanganate and Sodium Bisulphate should be halved. It is probably a good idea to do so with most films.

Metabisulphite Clearing Bath

• 30g Sodium Metabisulphite OR 35g Potassium Metabishulphite

• 1000ml Water
