Thank you so much, let me know if you have any questions.

Have you tried different sensitizer or developer ratios/concentrations to achieve greater contrast and Dmax? thanks for sharing your work. Look forward to the followup videos.

I did, and the results can be breath taking at least to my eyes. We have to keep away from dichromates and stick with the non toxic Ferric Ammonium Citrate and the hydrogene peroxide so that the gelatin can polymerize and trap the ink after exposure to the UV lights. However playing with the gelatin, citrate and ink ratios can have tremendous effects. I have a couple of examples that we'll discuss later on. And of course more studies have to be conducted to be more accurate. This video is just a proof of concept to show that carbon transfer techniques can be conducted safely. Thank you so much and see you soon.

Thank you so much for these videos I'm going to try this this summer. I was lookin for a safe way to do gum or carbon transfer prints but most of them are behind a pay wall unfortunately. I wish more people would openly share their experience because this hobby is so niche and a lot of information juist dies because people choose to ask like 200 dollars for a fucking video tutorial

You are welcome, knowledge should be free for all. It's really simple to do, good luck and let me know if you have any questions. Remember that you need oxalic acid for this process to work properly,

Hello, Habib. What type of printer model do you use to print the negative paper? I notice that the quality of the negative images is wonderful. Can you mention it? I need a printer of this type. I am waiting for your response. Thank you.

Hi, a great question. Those transparencies are from a $79 Canon imageCLASS MF3240 Monochrome Laser printer that I got from Fry's over a decade ago. I replaced it with another imageCLASS model MF262DW II from Amazon, unfortunately the LCD screen went dead after the warranty expired. Other monochrome laser printer like Brother didn't work well with transparencies, they tend to leave visible lines under the effect of the rollers when printing. I suggest you try to find an older model of the canon ImageClass series since they already have the option to print on regular transparencies or a newer ImageClass model that you can afford and select the image quality for both when printing. The transparencies I am using are the cheapest overhead transparencies I could find, they are like $5 a box of 100. Good luck and let me know if have other questions.

Where can I find more information about the CHIBA process? Google gives me nothing but your videos, but I'd love to find more information.

There is this pdf floating on the internet www.jstage.jst.go.jp/article/photogrst1964/70/2/70_2_106/_pdf There are a couple of active facebook pages : facebook.com/groups/chibasystem facebook.com/groups/alternative2 You are welcome to join and see what others are doing. I was very interested when I found out about CHIBA since it's safer than using dichromates. Here, you'll find my latest experiments and findings. Let me know if you have any questions.

Amazing! I have used Bichromat and DAS senteziser. Bichromat is way cheaper but toxic. DAS is hard to get super expensive when you print reagular and the stainig issue i never really fixed. Espacially when printing cymk as singletransfare. Your method might be the gamechanger espacially when teaching the process to inexperienced students. But one question…can ammonium citrate be replaced with sodium citrate or EDAT. I should work regarding the chemestry but would sodium citrate require higher concentration than ammonium citrate? And should EDAT not be less concentrated? I want to try your method but i only have EDAT / sodium citrate at the moment. Thanks for your input!

You are very welcome, I am not sure if sodium citrate is photosensitive. An alternative to ammonium citrate is ferric ammonium oxalate but I haven't tried yet. I use the ammonium citrate also for cyanotypes, it's cheap and can be easily found. Good luck and let me know if you have any questions.

Sorry about the confusion, the gelatin is already in tissue mixed with black ink and I didn't cover it in this video. We'll make tissues and show all details in the next videos.
