I have always worked with 1 to 1, but I'll try it.   I didn't label my
bottles.  Is A the darker one?

Have you tried mixing your cyano 2A:1B to cut down one stop?

I don't think the 15 min is out of line since I use Pictorico with gum and a
6 minute exposure.

Why aren't you using full strength am di? Or 15% perhaps, instead of pot di
to decrease your times, too?


Hi Loris,

My gums require 15 minutes with oiled negatives.  I would really like
to reduce this.  Also, cyanotypes made with the same oiled negatives
require exposure times of 30-45 minutes.  How does this compare with
others?  It seems pretty long.
