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.
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.
These schools and photography centers offer a variety of alternative process workshops and classes.
