Some photographers add a pinch of sodium sulfite before dissolving the metol to prevent oxidation, but large amounts of sulfite in solution will make the metol very slow to dissolve. Because metol is relatively toxic and can cause skin sensitisation, modern commercial developers often use phenidone or dimezone S (4-hydroxymethyl-4-methyl-1 ...
Alternative processes often overlap with historical, or non-silver processes. Most of these processes were invented over 100 years ago and were used by early photographers. [2] [3] Many contemporary photographers are revisiting alternative processes and applying new technologies (the digital negative) and practices to these techniques.
