Re: Blue-Black Cyanotype & Luster

I used some acrylic medium to brush over cyanotypes. It was several weeks
ago. I needed a waterproof cyanotype print. They all turned lavender and
bleached considerably upon coating. That was several weeks ago. I looked at
my test print today. The original dark cyanotype color returned, actually I
can not tell the fifference on the print that was half coated with acrylic.
The acrylic coated part has a nice shhen to it and the deep blues seems to
be darker, but the color is the same.
