The formula of Beutler is correct as is the 1 part A + 1 part B + 8 parts of water, but it is NOT the same as Neofin Blue which also uses hydroquinone and phenidone as shown in the MSDS for that particular product.
That is not to say that 1 part A + 1 part B + 10 parts of water wont work. |

The formula for commercial Neofyn Blue (original spelling) has changed originally it was just Metol, now it's Metol with a small amount of Hydroquinone according to the MSDS.
Ilford's high definition developer Hyfin contained Glycin, others a small amount of Pyrocatechin or Meritol (a fusion of Pyrocatechin and p-phenyldiamine). Ian |
