Ojizosan

This is a fantastic and truly unique image. Andrew ! Can you point me at a web link describing the technique you used, please ?

Thank you, Raphael. There is plenty of info on the internet about gum bichromate printing. You could check out alternativephotography dot com

This is really great. May I ask how many attempts did it take you to get there? Why yellow before magenta?

It took me many, many attempts... and I have 4 different ways to get there. One involves sizing the paper and Y,M,C. One involves no size and Y,M,C. One involves laying down K layer first, followed by Y,M,C, and M again. One involves K then C,Y,M, and M again. Each gives a slightly different look. For the Ojizosan, out of the 4 ways, the K then C looks the best. The Y after the C looked better than M after the C... that probably depends on the image. Next, I'll be making a negative to selectively lay down green on the leaves, to bring them out more.
I've learnt over the past year, that there isn't necessarily one way to make a print. I've also done away with pin registration. All the layers are thin enough ...and with the aid of a strong pair of cheap, dollar store reading glasses (+4), lining them up and taping to the image is easy.

@Andrew O'Neill : thanks you.
For whatever reason, I thought your tri-color process was something different from gum bichromate. However I guess it was a lot of work, a lot of try, and a lot of variable to tweak.

Tri-Colour gum bichromate is a lot more work than monochrome gum bichromate... especially for someone like me who has only ever worked monochromatic... my main work has been with carbon transfer and kallitype printing. I'm happy now that I can also add tri-colour gum to the creative process.
