Love your work, willingness to share, AND your enthusiasm. Cannot for the life of me understand why anyone would go to the trouble of throwing a thumbs down on this. Thanks for sharing!
Beautifull work Borut, if the negative has more or less contrast you increases or diminish the amount of dichromate and proportionaly the sodium hidroxide?
Borut, your carbon print on glass is the single most creative and best idea I have seen in a very long time. I want to try this too and see how it works out. I want to make sure I have your recipe correct. Can you verify? GLOP 250ml: 15g Gelatin, 7.5g Sugar, 10g Ink, 1g Potassium Dichromate, 0.1g Sodium Hydroxide
This is just a starting point. My negatives are dense. You may add more ink, like double ink for an ordinary silver-gelatin film negative. Be careful dichromates are poisonous, OK?
Thank you John, if who you understand the passion and the drive and the pleasure achieving a good print from start. It's like a a birth and guess what, also the second print got sold and it's going away in its own life.
Borut, there’s something special about creating art from your heart and then knowing it’s a part of someone’s life hanging where they see it, and inspires them. I do know that feeling having sold at shows!! Stay safe!!
Yes. If you use multilayered carbon print, then DAS is good. If you use negatives with maximum density 2,1 and single layer, DAS is good too, but I use very dense negatives and DAS has a huge threshold in the whites.
@@BorutPeterlinPhotography Thanks I may try it. I also found a site from Italy using DAS (or some similar azide) with gum arabic. That seems easier, since there is no transfer involved, the print is made directly on the final substrate. That itself puzzles me, as to why carbon prints need to be done on a plasticky surface, but gum prints don't. Something about the reaction of albumen versus gum with paper I presume. In comparing the two methods using dichromate, what is the advantage of the more complicated (I guess) carbon print?
I can't even buy dichromate here in the UK, I've been trying to get some to make my own cyanotype mixture. Nice to see a home-made UV meter, I'm working on one at the moment that will measure 355nm UV but also hopefully do visible spectrum too.
You don't need dichromates for cyanotype... if you're trying to use to control contrast, it would be better to work on tweaking your negative. The EU is basically banning the sales of dichromates. If you ARE doing a process that has traditionally required dichromates, consider switching to using diazo or DAS instead.
Hsh, keep it quiet, I'm competing for the title as the most underrated photography channel on the internet! Ha, ha, ha, but joking aside who knows what carbon print on glass is... That makes me think I've chosen the wrong title.
Borut Peterlin if they’ve landed here they’re in the wrong/right side of photography depending on how you look at it. It’s a beautiful thing. I wanted to say beautiful print but until this video I didn’t even know you could carbon print on to glass and now I’m not sure if anything anymore.
well, I was talking in principle. A dot as an elementary brick of an image. A molecule of silverchloride is in principle a dot. Invisible dot, but a dot nevertheless. In contrast to carbon print, where there is no dots, it's just pigment dispersed through gelatine. You need to see a carbon print on glass in person, then you will know immediately the difference.
This is so beatuful! How do you make so mush dense collodion negative? I saw in one video that you made the glass sensitive again after developing, but did not understand how? Anyway, what you are doing is great and motivates me to learn more and more about analog photography!
It's called redeveloping, but lately my workflow is perfected so I get bulletproof density with one development. I think I've made a video on that, 6 or 7 years ago.
@@zaytsevvaleriy yes, basically. But it's too long and complex to explain in a comment. Google my video probably entitled wet plate collodion, salt print or albumen print.
Fantastic print! congratulations, your art is in continuos emprooving!!! Could we know why in this case you use dicromate instead DAS? ther's a tecnical reason or only a logistic one?
Das is great for negatives up to 2.0 dMax density. Above that dMax I struggled like crazy to get good tonality, but in vain. Das has a huge threshold in highlights and then suddenly jumps to gray. Really ughly. I adapted the receipt for nice tonality in highlights and I got them, but at the cost of shadows and blacks. To make a great carbon print with das and analogue dense negative, I would need to go with three different layers.
@@BorutPeterlinPhotography Thanks for the explaining, this means that is possible using das with glass print, and it depends only on the density of the negative. right?
I started doing carbon earlier this year. I had not heard of putting the dichromate in the glop but I agree that sounds like a better way of doing it. But when you do that don't you need to keep the tissue away from light? The video shows you hanging and cutting the tissue wha looked to be normal room light? Also, where did you get that UV meter? It counts backwards after you put a set number in there? I think you may need to write a book on your carbon transfer technique. Great video
Apparently in the beginning of the invention, so in the 1850's, they mixed dichromates in the glop. I am an artist, I'll pursue my artistic vision. Once I could not go on, then I'll start cashing in the knowledge I have with manuals. Read my previous reply on UV meter.
ha, ha, ha... half an hour of cleaning the whole kitchen would be a nice day to start in the comparison to cleaning my darkroom, ha, ha, ha... Thank you mate!
How are you drying the tissues if you only have so little time? I really want to use this method since I want to use as little dichromate as possible but I'm afraid the drying alone will take up the 2 days :(
As a teenager I worked in a lab specialized for cibachromes, but not as a printer. Yes, they have this amazing glossyness that does somewhat resembles the silkyness of a carbon print.
Well, it's not the safest thing on earth, but frankly I believe that my job of photoeditor, sitting behind a computer, took a greater toll on my body, then this photo process. But that said, safety measures are very important
Love your work, willingness to share, AND your enthusiasm. Cannot for the life of me understand why anyone would go to the trouble of throwing a thumbs down on this. Thanks for sharing!
Yes yes yes the reflected light definitely makes a difference - Stay Safe
Michael! Us Philly boys are winning this Pateron thing!
This made my day. Love it, sir!
Would luv to learn how to do this. The process I do with film produces a similar relief.
like your confidence ! essential tool for life ! fine print !!!!

Very beautiful work! I also was wondering about DAS, you've answered it. Sounds like it is a possibility, but very tricky depending on the negative.
Yes. If you use multilayered carbon print, then DAS is good. If you use negatives with maximum density 2,1 and single layer, DAS is good too, but I use very dense negatives and DAS has a huge threshold in the whites.

Ask an offset printer who has some stock left. They are trying to get it rid of, you just need to find one. Ask, ask, phone call, email,...
Borut Peterlin huh I had no idea offset printing even used it. I will have a go.

Great job! Keep it up! Bravo!!
Super process! And the result is splendid :)
I was wondering do you coat your glass with gelatin to transfer? Or Albumen and alcohol?
Thank you. No, gelatin sticks to clean glass.
@@BorutPeterlinPhotography So Albumen then :)
is there a book you could suggest . on the carbon print on glass process
Continuous tone images (albumen, etc) do not have "a dot" or dots. That is halftone printing.

@@BorutPeterlinPhotography so it is like pour another portion of developer after fixation or there is another mixture? Thank you!
@@zaytsevvaleriy yes, basically. But it's too long and complex to explain in a comment. Google my video probably entitled wet plate collodion, salt print or albumen print.
this is so f'in cool
Great video and really nice result. I was just wondering if you do something special with the glass to stick the albumen on?
You mean gelatin. Yes, I sub it with diluted albumen and harden it with alcohol. But it works also if the glass is well cleaned.
@@BorutPeterlinPhotography thanks

No, the tissue isn't that sensitive, especially not to tungsten light.
Borut Peterlin are you using DAS as well to Sensitize the tissue?
What a great video to start a day (after half an hour of cleaning whole kitchen) :)
ha, ha, ha... half an hour of cleaning the whole kitchen would be a nice day to start in the comparison to cleaning my darkroom, ha, ha, ha... Thank you mate!
@@BorutPeterlinPhotography It wasn't very messy - still got to go with bathroom and all those little flying german furs everywhere :)
@@kubagornowicz you see, here dichromate and silvernitrate comes as an advantage, since everything dies in my darkroom.
Very interesting!
How are you drying the tissues if you only have so little time? I really want to use this method since I want to use as little dichromate as possible but I'm afraid the drying alone will take up the 2 days :(
9:52 Is that a 7.5 gr Sugar?
did you ever try cibachromes/ilfochromes? i luv 'em
As a teenager I worked in a lab specialized for cibachromes, but not as a printer. Yes, they have this amazing glossyness that does somewhat resembles the silkyness of a carbon print.
Smart guy.
I have to learn that... :)
I owe you one and this printing process is really beautiful!
why can you get the glass plates from ?
From a glass cutter. Ordinary glass.
Where can I get that UV meter!? :)
It's home made, but it isn't really precise. It has to measure also other visible light to be more consistent.
@@BorutPeterlinPhotography even more awesome if its selfmade. :)
Do you have any issues obtaining chemicals. Sounds like a dangerous business especially for your health
Well, it's not the safest thing on earth, but frankly I believe that my job of photoeditor, sitting behind a computer, took a greater toll on my body, then this photo process. But that said, safety measures are very important
