Salt Printing from A-Z

- This video describes how to make salt prints, an old technique developed by Gent Henry Fox Talbot in 1839. It uses silver nitrate solution and salt solution to create a light sensitive emulsion.
I used 12% silver nitrate and 2% sea salt solution.
Don't blame fox Talbot. He enlisted the aid of John Herschel, the then head of the British Royal Academe of Science and a chemist. Daguerre and others based their printing processes on his work with photosensitive chemicals and methods of "fixing" images. I very much appreciate your underlying (or over riding) sense of "cheap." My contact print frame could have been a $119 printing frame from B&H but turned out to be a 16x20 frame less photo display costing $9.00
Your negative is not strong enough for salt printing. If you must use film negatives place three or four layers of tracing paper over the printing frame to support the self masking element of the printing out process. It will hold back the highlights allowing the dark areas to print deeper while keeping the highlights white.
Beautiful!!
I’m so excited to see you do the paper negative. I’m a Printmaker and Bookmaker. This technique will become part of my book pages. I’d love to take workshop with you. This is valuable information for a 79 years old still working in studio after retiring from 30 years of Critical Care and Emergency RN Nursing. You’re awesome.
Thank you. I stil occasionally do paper negative. I appreciate your kind words.
Kris. You better use a Chinese flat goathair brush to apply the sensitiser to the paper.
In the end I gave natural brushes away and jut=st use a soft nylon brush from the hardware store., They work beautifully, and no lose hairs. :-)
I had before will soon experience the negative printing by silver nitrate and gelatin, salt solution, but unfortunately I can not image stabilization for a long time does not Nha become black little by little because I did not get Sodium Hypo acid solution in my country because it is difficult does guide me to an alternative I can get it from kitchen utensils materials, for example, or a similar alternative O'Shea which can be accessed easily in order to be able to install the pictures for a long time and I will be very thankful to you
esto ha sido como un video de los años 20 sin subtitulos los que no dominamos el ingles lo tenemos dificil, es una lastima que desactives los subtitulos, por eso no te doy un voto positivo y me voy sin ver el video lo siento mucho de verdad, me hubiera gustado ver todo el video con subtitulos al menos se podria entender.
Hi, I will be happy to reactivate the subtitles for my spanish speaking viewers
Great video, thanks! It looks very simple to do, I'll have to give it a try. Are you planning to cover some other alternative processes in the future?
very good video, I was wondering, do you size the paper before printing on it?
J John Golden For larger prints, like 8x10 I like to leave an edge around the print. I put the negative and mark the edges, then sensitize the print.
But... why didn't you show the paper negative final result?
Results are at the end
I thought you showed the print from paper before then fixing, maybe I missed something, sorry 😊
A really nice demonstration. I use paper negatives but brush them with vegetable oil. I wipe the excess oss then leave them for a day or so. My exposure times in sun here in Australia are around 2-4 minutes in clear skies. I've fond that paper negs years old work just as well as fresh ones.
Hmmm quite an interesting approach.
The oil makes the paper more translucent but also reduces the density of the dmax areas of your negative. Talbot waxed to make the wove pattern of the paper stock less noticeable. Try adding density to areas of the negative with a pencil with the negative on a light table.
Is the Belgian cream puffs required or can I leave that out? Seriously though, thank you so much for this video. learned a ton!
Chris Pugh Photo so glad that you found this useful. Cream puffs are good addition but not mandatory.
Can you offer any advice on buying silver nitrate crystals? I just want to make sure I get the right ones.
Hello, go to Bostic and sullivan website. They sell everything you will need.
how long did you let the sensitized papers dry?
itaborai83 it took around 45 minutes in 72F temperature
Kris Bochenek and how about after salting it? 45 minutes as well? great video, btw =)
Until dry to touch. I try to give it 30 to 45 min
Kris. That's far too long. Speed up the drying with a hairdryer, this will prevent the emulsion sinking too deep into the paper fibers, giving a snappier print.
