Anyone here ever print cyanotype, vandyke brown, kallitype, etc? I have a vandyke kit with gold toner on order. My ultimate goal is to learn Platinum/palladium printing.
For those not familiar with with these processes, generally they are done via contact printing. The negative is the same size as the print. Prints are made by coating watercolor paper with the photographic emulsion with a paintbrush, sandwiching the negative against the coated paper, and exposing it to a UV light source. (most commonly, the sun)
This is a very analog process by the way. So much so that most of the techniques go back to the beginning of photography itself.
Platinum/Palladium prints are very beautiful. Almost 3D prints with huge tonal range. Here's an example.(Not mine. Just posted here so you all can see.)
Again, this is chemistry coated on watercolor paper and exposed by the sun:
edit: by the way, yes you can do this with a digital camera! You just have to create a negative and print it on transparency. In a lot of ways, it would be easier with a dslr because you'd get to skip all the steps that involve film. A lot of people who do these shoot with large format cameras to get a big negative without enlarging. I plan on scanning images taken with my 67II and having the negs enlarged digitally.
