RE: cyanotype and silver image (was Re: Cyanotype toning and lead acetate.)

Chris and Ryuji,

As I recall Suzanne Izzo has been very successful using cyanotype over VDB.
If I remember correctly one or the other or perhaps both the cyanotype or
VDB solution is diluted with water. She was kind enough to gift to me two or
three of her combo prints and they look great. What ever she is doing it
works. Perhaps she will chime in if she isn't still traveling and away from
her computer.

Here are some of my notes, Ryuji:

One student did a grossly overexposed VDB, essentially a brown square, and
did the cyano over it and it was gorgeously weird, but certainly not a
perfect print. I can send it to you offlist.

The one that used the gesso did VDB overexposed, two coats of gesso acrylic,

matte medium and water in equal parts on top of that, then cyano on top
overexposed. It amazed me that even through the gesso coating the chemistry

was able to alter the VDB below.

Most found that the best way was to do the cyanotype first, then a VDB on
top, and even misregister it. For some reason misregistration looks good.
Also, diluting the VDB on top of the cyanotype and a return to an acid bath
for the combotype after everything is done, to return the blue of the
cyano..

But my guess is for a combotype that the better way to go (I mean, a
brownprint and a cyanotype) would be pt/pd and cyanotype over. I know I've
seen Sam Wang's duotone palladium/cyanotypes made with color separation
negatives and they are really beautiful, an odd tone where it looks like a
desaturated color image. And these combotypes of VDB and cyanotype don't
appproach that fineness.
