In a thread at Flickr, I discovered this picture of Marschal A. Fazio (Pothman), that he made using Rodinal and hair dye in a reversal (?) process. He says:
Since yesterday I am trying to reproduce the experiment, I have nothing really exciting yet to show you, but maybe some of theses days, who knows.
Report of what I have tryied until now:
I prepared the developer like suggested, 3-4 ml not of Rodinal but self prepared Parodinal for 500ml water and about 10ml hair dye, but not the same brand of Loreal. I was so convinced of the success that I went out and exposed a 36 Agfa 100 and developed with this developer. After the first development I filled the tank with a bleach bath of a Tetenal kit for some 4 minutes and oppened the tank to expose the film to light. I expected a blank film but no, it was developed in black and white, looked very nice as black and white pictures. I submitted then the roll to a stronger bleach, Potassium Dichriomate + Sulfuric acid and the result was to bleach out almost all, leaving the roll damaged. No, this way it doesn't go. I need another bleach bath...
I exposed then short pieces of film at home and tried again, the same developer but as bleach I used this time Betadyne which takes hours to act but goes safer. I bleached for some 3 hours and then exposed to light and redeveloped. I have got color pictures but very weak. This was yesterday!
Today I restarted exposing small pieces of film at home and develop them using Parodinal and hair dye. I read somewhere that Parodinal or Rodinal alone is a very weak color developer too. So, this time I took as first developer only a 1:50 solution of Parodinal for 10 minutes only, stiring constantly. Then I submited the film to 45 minutes Betadyne and the result was a almost B&W developed film, without the orange mask, the Betadyne removed the orange mask but leaving the silver untouched. I divide the experience in two parts, cutting a portion of the film to be fixed and washed like it was and the other portion I left in Betadyne for one hour more, controling the process until I see that the silver was bleached leaving a little a weak image of dye. Then I redeveloped in the same Parodinal with two spoons of the first prepared developer of hair dye. The image got more density althought the color restitution is not that good.
|Example of the first part, bleach during 45 minutes with Betadyne|
|The same image warmed with software|
|Direct scan of the 2 hours bleach + redevelopment with Parodinal and a little hair dye only|
|From the same second part but enhanced with software|
I wonder what could have happened if I used a little more hair dye in the second developer.
