[alt-photo] Don't take the brown FAC!

[Trevor Cunningham]

Hey gang,

Well, after a long wait, I finally have chemistry for gum and 
cyanotype...or so I think. I opened my FAC and discovered that it looked 
VERY brown. After mixing according to the traditional cyanotype in 
alternativephotography.com, it doesn't have that iridescence I remember, 
and the dried emulsion is brown. I haven't exposed one yet because my 
sun decided to hide for the rest of the day's useful light. In the 
Unblinking Eye, there's mention that the brown FAC is less sensitive and 
has a lower tonal range than the green. Should I be making an effort to 
reduce contrast? Any suggestions as to how I might alter the solutions 
to compensate? Something tells me I'm going to have to really dial in a 
specific curve for this ride.
