A video I made on the Rawlins oil process for a friend. The narration is unfortunate as it was not intended for the public but I posted it anyway in case anyone was interested. There's not a lot of info on the Rawlins process but I hope to add more because it's just such a great technique.

Hello Jeff, after a lifetime of commercial photography, this is just what I needed, beautiful process, wonderful image, thank you. Darkroom being built this year !

Hello. Tell me how to remove the strong shine of the gelatin base. It is so strong that it partially covers the image itself.

Nice video. It's sad that you've only posted two of these and only one of your dogs.

Hello Jeff. It's me again :-) I have a question if I can use contaminated ethanol instead of isopropyl alcohol? That's the specifics: Rectified alcohol (ethanol 96%) is a non-extraneous aroma, a versatile cleaner and degreaser. The product is intended for diluting fragrance compositions, paints, polishes and resin varnishes. Used for the production of perfumes, deodorants, colognes and hair sprays. Chemical composition: Ethyl alcohol: min. 96% Methanol: max. 500ppm Acidity: 15.2-30mg / l Water content: max. 4% The content of higher alcohols: 3.2-5mg / kg Density: 0.799g / cm3 Completely contaminated in accordance with the Commission Regulation (EC) No. 2016/1867 of 20/10/2016 (universal European recipe)

Well done! I wonder what the prepared negative looks like. Oil printing is a contact method. I like this technique very much because I can use a digital negative. Unfortunately, I have no idea which transparency film to use for printing, and how to properly prepare such a file in Photoshop. I'm a bit confused. There are a lot of different tutorials

Hello Rafal! I dont know about digitl negatives but looked at 3 carbon transfer printers and found that Sandy King uses the following info to create his negatives, good luck! precisiondigitalnegatives.com

@@jmmichael188 Thank you for your answer. I have one more question. In what proportions you mix the solution of potassium dichromate with acetone? Does acetone accelerate the drying process or does it have a different purpose? I have never tried this technique. I'm just getting knowledge about it. But I must admit that the effect is magical.

@jmmichael188 5 лет назад

Yes acetone is used to speed up drying time, also it allows the dichromate to absorb quickly into the gelatin and keeps the mixture cold as acetone evaporates very fast and causes a cooling down of the gelatin. I mix a 10% stock solution of potassium dichromate and cut it in half with acetone to get a 5% working solution.Here is another video of mine; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-avx5mIRKvgc.html And another that I found inspirational as I was learning the process. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EmpTgDlsr3o.html Thanks!

Thank you, Jeff. Your help is invaluable. Of course, the more I start to understand, the more questions I have. I'm afraid that I fell into a trap and I think I will try this technique :-) I managed to get some information about digital negatives. So, I think it's time to buy chemicals. Best wishes and good luck.
