Mix your own photo developing emulsions

If you’re into developing your own photographs you might try mixing your own emulsion. [Jimmy Hartnett] worked out the chemical reaction necessary to make a photosensitive medium using Silver Chloride. His process lets him manufacture canvas that can be use like photo paper. The gist of it involves coating the back of a canvas with Gesso to prevent the emulsion from passing all the way through. He then floats the canvas face-down to apply the emulsion and skims it with a straight edge before it has time to set. You can see the results of some contact print testing in the image above. If anything, this makes a great piece of art to hang on the wall as it’s visually interesting and [Jimmy] has a personal connection because he not only made it himself, but came up with the process.
