I am developing B&W film in a monobath I discovered, made with Parodinal and salt:
3 ml Parodinal
150 g salt
water to make 500 ml
Develop for 24 hours at room temperature or 4 hours at 35ºC
After developing, wash the film very well and dry. You would be surprised that it may be scanned reflective as a positiv picture, using a black background. Use medium or large format and the film can be used as the photo mirrored like a daguerreotype.
Scanned and inverted? Or when you scan it, the highlights are white?
