The term alternative process refers to any non-traditional or non-commercial photographic printing process. Currently, the standard analog photographic printing process for black-and-white photographs is the gelatin silver process.[1] Standard digital processes include the pigment print, and digital laser exposures on traditional color photographic paper.[citation needed]
Alternative processes often overlap with historical, or non-silver processes. Most of these processes were invented over 100 years ago and were used by early photographers.[2][3]
Many contemporary photographers are revisiting alternative processes and applying new technologies (the digital negative) and practices to these techniques.
Examples
edit- Anthotype
- Caffenol
- Daguerreotype
- Gum bichromate and other Pigmented Dichromated Colloids which are used to directly generate a photographic print
- Platinum Process and Palladium Process
- Carbon print and various similar processes which use a non-sensitive intermediate layer to generate a photographic image
- Van Dyke Brown, Cyanotype and various other iron-based processes
- Wet and Dry Plate processes based in silver using a hand coated emulsion on a tin or aluminum (tintype) or glass (ambrotype) base
- Resinotype and several similar processes which rely upon unexposed dichromated colloids to accept an insoluble pigment
- Inkodye, a light-oxidized vat dye.
- Oil pigment processes, such as bromoil process
- Other processes which use silver halide but in various different ways other than the typical silver-gelatin formula, such as Salt Print
- Any number of processes which use more exotic materials, such as uranium chloride, gold chloride, and any number of other salts to directly or indirectly generate a photographic print
- Non standard digital manipulation or printing.
Learning
editThese schools and photography centers offer a variety of alternative process workshops and classes.
