Excellent! I love the result . It s a green process. Thanks a lot from Argentina

[@saidanehabib]

Thank you so much.

[@TheStockwell]

Brilliant! Absolutely brilliant. The work and time you've put into this process is astounding. Best wishes from Vermont 🍁

[@reusedisland1904]

So Hands-on - Love it! From Vancouver 🙏

When you say "citrate" are you referring to Ferric Ammonium Citrate?

[@saidanehabib]

That's correct.

[@pagirardi]

Thank you for this video ! Apparently it's the Chiba system. Do we know the durability of this print ? Will it "fade" with time ?

[@saidanehabib]

You are very welcome. With the right pigment, CHIBA prints should not fade, the reason after exposure and when developing with hydrogen peroxide the gelatin or glue polymerizes and traps the ink inside. Unlike cyanotypes, the chemical reaction in CHIBA is one way and is irreversible when exposed to more UV lights after developing the image.

Do you give online tutorials on this method?

[@latinhermes]

hi! the negative is from an imagesetter? stochastic plots?

[@saidanehabib]

The negative is just a print on a cheap transparency using a cheap ImageClass Canon laser printer.

[@itspeache]

Wow cool!!

[@saidanehabib]

@@itspeache thank you

[@lisabakke9280]

Wonderful and you used a digital negative?

[@saidanehabib]

@@lisabakke9280 thank you, yes digital, regular overhead transparency printed on a Canon imageclass laser printer.

[@avalonparadea9820]

By "citrate" do you mean ferric ammonium citrate? Are there other types of citrate that can be used?

[@saidanehabib]

Correct, Ferric Ammonium Citrate. Ferric ammonium oxalate can also be used.

[@avalonparadea9820]

@@saidanehabib mahalo/ thank you for your quick reply! I am very new to think process so apologies for all the questions. Are you simply rinsing the final image in regular water?

[@saidanehabib]

@@avalonparadea9820 You are very welcome, ask as many question as you want. It's a safe process. Correct, use regular water for rinsing. To develop use 0.3% (point three percent) hydrogen peroxide.

[@robertfiss976]

Greetings, and I apologize in advance, for this question. I create cyanotypes, and I love learning new processes . Did I miss a step where you expose the paper with a negative to create the image? Thanks again

Bravo!!! Can replace oxalique acid with citric acid ?

[@saidanehabib]

Citric acid should work too.
