HD3 (under tests)HD3 is a C-41 color developer using a PPD hair dye. It was inspired in the work of Robert Neelin that can be found at Flickr.
50ml hair dye containing PPD
5g Sodium Hydroxide
10g Sodium Bicarbonate
5g soluble coffee
2g Potassium Metabisulfite
Water to make 500ml
Develop for some 20min at room temperature.
Hair dye is oily and difficult to dissolve in water. Because soap is made adding lye to oil, first combine the hair dye with about 10% (5g for 50ml hair dye) and let it react stiring a lot first and then from time to time during 3 hours. There is a slight color change for the mixture, it turns darker. The pH is very high at this stage.
So, mix all content of a 50ml hair dye package (only the part containing PPD) in some 100ml warm water in a beaker. The same for the 5g Sodium Hydroxide in a separate beaker. Then add the Sodium Hydroxide to the hair dye and stir like described above.
After 3 hours, add 10g of Sodium Bicarbonate to the mixture. This produce Sodium Carbonate and pH of the mixture will drop to between 11-12.
Finally add 5 g soluble coffee and 2 g Potassium Metabisulfite.
Copper Sulfate BleachCopper Sulfate Bleach was suggested to me by Murray Kelly at ipernity.com.
50g Copper Sulfate
50g Sodium Chloride
500 ml Water
5-7 minutes at Room temperature
100 g Potassium Metabisulfite
36 g Sodium Hydroxide
29 g Sulfur
1000 ml Water
First dissolve separately the Metabisulfite and Hydroxide, each in about 500 ml water. Then pour the Hydroxide solution on the Metabisulfite. In this step you are preparing a mix of Potassium and Sodium Sulfites.
Bring this 1 liter solution to the fire and when it starts boiling lower the flame and add the 29 g of Sulfur. Let it boil slowly and stir. At a certain point the Sulfur sinks to the bottom. Wait some more minutes and then switch off the fire. Let it cool and filter the solution with coffee filter. Not all Sulfur reacts, but you will end with Potassium and Sodium Thiosulfate and the remaining unreacted Sulfites.
Use the solution you got, about 700-800 ml, undiluted. It takes 5-10 minutes to fix.
