Gum-Over Cyanotype Print

- I decided to make a large gum-over Cyanotype print of an image called "Pathway". The original image was exposed in a Mamiya-Six Folder (with 720 IR filter) on Rollei IR 120, and then scanned so that an enlarged digital negative could be made. The paper used for the print is Revere Platinum.

That was a pleasure to watch. Nice work! 🙂
Thanks for this very relaxing video
That trichromie process is quite long. A real patience test
At first, I thought the stones were potatoes ... Must be hungry LOL
That's exactly what my sister said when I was making a carbon transfer print! 😄
Where did you learn this process? I've been impressed with your knowledge of photographic processes, obviously you've been at it for some time. I'm curious as to what you do with your finished prints, hopefully not like me where they go on my wall or in a box with many other prints. Thanks for sharing!
Thanks Steve. I've been into photography since about '91. My formal training is in drawing, painting and printmaking. Found the darkroom more fascinating. Been into Alt. printing now for close to 20 years, as it connects me with my printmaking past. This gum-over is just a twist to tri-colour, which I'm also into. My main is carbon printing, though! It's fun bouncing between them all LOL! The prints that I'm pleased with go up on the wall. I replace them occasionally. The ones that make it to my wall end up in a box. I was exhibiting quite a bit until 2015, then I took a break from that. I'll probably start doing that again after I retire. It's a lot of work, especially in Canada where artists just aren't appreciated. It's so much different in Japan! A lot more respect for the artist and for the teacher over there! Cheers!
@@analogueandy8x10 same here in the US, not much support.
Excellent. What were you doing at 10:26 with the brush after the red layer?
Thanks! I was doing a little selective removal of the red layer.
I've been watching your videos recently. I am very impressed with the results achieved. I'm also trying my hand at bichromate gum and cyanotype. So far, I have only made monochrome prints. I am very interested in introducing color into cyanotypes. I'm curious if you use only one negative in the presented film? In what proportions do you combine colored solutions to gum values? Regards.
Thank you for watching and commenting! For the straight gum-overs, I'll use two digital negatives. One for gum and one for cyanotype (or kallitype if the base is a kallitype print). I've gum overs for14x17 xray negatives, only using one negative, and have been happy with the results. I'll have to get back to you on the proportions as I'm teaching right now...With this method, one doesn't have to be so exact compared with tri-colour gum, which I also do...
Thank you for your answer. I meant the proportions of gum arabic to dichromate. Are they the same or maybe different?@@analogueandy8x10
Sorry abou that!@@jaretzki131 It's 1 part gum to 1 part dichromate for all.
The gum added literally no colour to the image, why was it needed?
The gum was laid down to subdue the blue of the cyanotype. It's more neutral toned.
It would be helpful if you would explain what you are doing. I could not follow what you were doing after the initial exposure and rinsing of the print.
It wasn't meant to be a how to video but I do have one planned...Thanks!
great work but i think so much water consuming in this prosces that made it not very interesting.
For a two-colour gum over Cyanotype, I use 30L of water. That is why I use a bucket.
