RE: what I've learned about cyanotype thru PDN

Hi Christina,

I don't know about Don's test (what he tested and how) but double
coating definitely changes Dmax with classic cyanotype. I get much much
stronger Dmax when I double coat. Also the contrast of the emulsion
changes considerably (it becomes more contrasty).

Regards,
Loris.
