Hi,



9x12cm Gum bichromate (Zeiss Ikon Maximar 207/7)

I am going back to gum, picture is not technically perfect but what do you think about this technique?

Getting a perfect gum print is not easy. Personally, i think the imperfections of a gum print make it unique. Sort of like it's signature.
Nice image though.
What paper is the image on?
Did you size it?
How many layers?

The paper has a visible structure. Its made of hemp fibers. Paper is not good because gum stick to his surface (I do not use gelatin before the gum layer). The only advantage is that it is very bright white.
No, I do not use any gelatin coating or any other.
It is only one layer - twice coated with gum and pigment before exposing to light.
Print is made directly from the film negative (contact print).

Gum printing as a technique is not easy but allows artistic self-expression, I think. Keep at it. BTW, the paper looks interesting and for a one layer image, it shows good detail.

Nice one, jp! It's almost a human portrait!
I've been running into a lot of issues with new cyanotype lately; it's extremely cumbersome in comparison with classic cyanotype. Currently I have severe fogging issues unless I use a very acidic first wash, which consequently bleaches out almost the entire image during drying. It's ability to deal with contrasty negatives is appealing, but the process is a total b*tch in all other respects.

It's only my 3rd print with the new chemistry. I add a drop of citric acid and a drop of tween 20 before coating the paper and rinse in plain water and they were good. The next print after this would not develop/rinse; stayed pretty close to how it came out of the contact frame, and it was coated/dried/exposed simultaneously with this print. Nothing wrong with traditional cyanotype chemicals, except they print slow on heavy duty paper like this.

JP, nice image! True, almost looks like a face!
I still use the old cyanotype chemistry and am satisfied with my results. That is probably more a function of my low standards than anything else. I also bleach and tone my cyanotypes or use them for gum overs.
