Carbon Transfer Print: A Larger Version! 

That's probably acrylic medium, which I use to size the paper support with. I use either matte acrylic medium or glossy, depending on the image. I dilute it 1+1 before use.

Is it just color or is it needed to get the gelatine better?

As long as the mated print and tissue sit flat after squeegeeing, nope. No glass. They sit on the counter, and wait while I prepare the development bath. If they don't sit flat, then I'll lay a piece of glass, but only for as long as it takes me to prepare the development bath... which is only a couple of minutes.

@@analogueandy8x10 Cool! I'll give it a try ;) Tested mating and instantly submerging... Did not produce nice results...

@@itsskin the paper sizing may have something to do with it... how do you size your paper? I use acrylic medium.

@@analogueandy8x10 Same as you

@@itsskin my development temperature is around 43-45C and peel tissue after about 3 minutes.

I run a minimum time maximum black test strip through a scrap piece of film. I usually end up tweaking the time a bit, along with the dichromate percentage. Have you watched my carbon transfer series videos on my channel?

@@analogueandy8x10 thank you so much Andy! That makes a lot of sense. I have watched two videos on carbon transfer on your channel but will check out the whole series now. Thank you for sharing your knowledge and experience!

Since the video wasn't about digital negatives, I decided to leave those details out. The actual density of the 8x10 in-camera negative is mentioned in the video leading up to this one (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--wg6zRL9hTM.html). It's also printed in that video. For this video, a digital negative was used. I have always used QTR, and Charthrob to generate a curve. Thank you for commenting! I really do appreciate it! 🙂
