Judy,

The cyanotype curve on the right of this linked image has worked well
with me for OHP, traditional cyanotype formula, and prints on Cranes
Kids Finish ecru. You might use it as a starting point in deriving your
own curve:

I tried Burkholder's curve too and had to adapt it for my materials.
There is also a pair of curves on the left of the image for van dyke
brownprinting if anyone is interested.)

I also would repeat that solarization with cyanotypes and bronzing with
POP are indicators of sufficient exposure. Did you see these with your
exposures?

I used Dan Burkholder's template; adjustments to the curve will be my
next step in the learning process, along with trying to figure out about
the densitometer options on my scanners' software (I use either the
Polaroid SprintScan 4000 with SilverFast Ai or an Epson 3170 to scan
35mm film.).

Thanks! JT
