Some people prefer the 2:2:100 dilution as it is more energetic and develops a given film faster to the same contrast. I calculate that you reduce development times with the 2:2:100 dilution about 35% compared to the 1:1:100 dilution. In other words, if your standard is ten minutes with the 1:1:100 dilution, try about six and one-half minutes with 2:2:100 to get the same contrast.

Can this be done for Pyrocat-MC either?
 
35% down or 50% up

Eddie,

Your math is correct.

Hello Sandy,

Just to be sure, should I increase the time by 50% if I use the 1:1:100 instead of 2:2:100 dilution?

thanks,
Armando
