I have been fooling around with reversal processing 4x5 paper negatives exposed in-camera for a while now. I decided to try sepia toning the reversed print. This involves an additional bleaching and development step. The bleaching this time is halogenating, meaning it actually resensitizes the dark portions of the image, as opposed to the reversal bleach which does not.
The steps are:
- Expose preflashed Arista Edu #2 graded RC paper in camera at about ISO 3, depending upon UV content of light.
- Develop negative image to completion for 90 seconds in Ilford Multigrade, 9+1 (very dark!!!).
- Rinse, then bleach in R9 potassium dichromate/sulfuric acid.
- Rinse, then clear orange stain from bleach in sodium sulfite.
- Rinse, then re-develop to a positive image in "Iron Out" rust remover.
- Rinse, then re-bleach in a rehalogenating bleach of potassium bromide/potassium ferricyanide.
- Rinse very well. Develop a third time in sodium sulfide sepia toning solution
The results were quite good:
