Re: Tricolor nr 3

That makes me want to get back to a project I started and set aside a couple of years ago. I don't remember now what the images were that I wanted to use this effect for, but I was experimenting with different combinations of complementary colors to create different kinds of greys. Depending on the colors chosen and the concentrations, you can get everything from silvery to pearly to pewtery greys, warm to cool, light to dark. If anyone is interested in pursuing such an exploration, I recommend the solution I finally hit on, to print the complementary colors on mylar and then just overlay them on each other to pick the combinations you like. Saved a whole lot of work printing all the different combinations of pairs one at a time.

Mixing paint can give you an idea of how colors mix, but I wouldn't recommend it for trying to determine how colors will print overlaid in the gum process; for that, you really have to print the gum layers. This really belongs in another thread, but I'll just throw it in here, though I think I've said it before: the only reliable way to understand gum printing is to print gum.

Thanks, Henk. I love this photograph (what a wonderful composition). I also think there's a really interesting quality to monochrome gums; I've done some on unsized Fabriano (one coat), which I really liked. I saw some monochrome gums in a gallery recently, made by Sookang Kim. Although the prints appeared as a monochromatic gray, they were done in multiple layers. I'm not sure, but I'm *guessing* each layer had a slightly different hue to it, though that certainly wasn't obvious in the final print-- so not sure about that-- but just exquisite work. I was amazed anybody could achieve such a quality with gum.

Hi Diana,
The first one was the son of my son, the last one the son of my daughter.
Started with bromoil printing (no big negs needed :-), thanks to Judy's PostFactory i made the step to gum.
Mainly monochrome, also as an alternative to cyanotype, like this one :

Hi Henk,

I just now had a chance to see this-- what a beautiful photograph and print. Is this the same grandchild in a print you showed some weeks ago-- that was also a gum? You've obviously been making gum prints for a while, I'm guessing. Anyway-- really lovely print and image. I love that steady gaze into the camera. Thanks for posting.
