Alternative Photographic Processes
Many photographic traditionalists still, in this digital age, practice photography using film. By embracing the capabilities of digital it is now possible to continue to use film and then to scan the film as a digital file. The question is why would anyone even use film if the end result was going to be a digital file.
The preparation of glass for receiving a carbon transfer is critical to the longevity of the print. Meticulous cleaning minimises the possibility of impurities damaging the print and correct preparation for bonding ensures that the print will not separate from the glass.
Photographic carbon printing depends on the effect of light on carbon tissue (a gelatin film) which has been sensitised by treatment with potassium or ammonium diochromate.
Practising carbon printing today can be a challenge due to a lack of literary resources. Carbon printing is a technique dating back to the early 19th century. Despite its lack of popularity today it is still considered to be the most archival of all the photographic processes.
