An earlier version of the formula published on the rec.photo newsgroup called for 2.5 grams of metol in place of the phenidone. |
Developing agents most readily available were metol, hydroquinone, and Phenidone. |
As I have explained in my Print Solarization article, the best developer for the Sabatier effect is one that contains metol only. |
The same remarks as to over and under-exposure apply as in the case of Metol. |
