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 The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography r ...

. Standard digital processes include the pigment print, and digital laser exposures on traditional color photographic paper. 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. Many contemporary photographers are revisiting alternative processes and applying new technologies (the

Carbon print A carbon print is a photographic print with an image consisting of pigmented gelatin, rather than of silver or other metallic particles suspended in a uniform layer of gelatin, as in typical black-and-white prints, or of chromogenic dyes, as in t ...

Salt Print The salt print was the dominant paper-based photographic process for producing positive prints (from negatives) from 1839 until approximately 1860. The salted paper technique was created in the mid-1830s by English scientist and inventor He ...
