A method of Silver Gelatin printing using high contrast developers to  change and control contrast and tonality. Lith prints are often high  contrast, displaying a red / brown tone in the midtones with strong  black shadows. However, the process is variable and the contrast and  tonality is further manipulated by changes in print exposure and  development.

An unprocessed sheet of photographic paper will eventually turn from  white to various shades of red or purple if exposed to light but not  processed. If an object comprising of organic matter is laid on the  paper during a lengthy exposure, an image can form due to a chemical  reaction between the paper, light and the object being printed.

An experimental process using a strong bleach and re-development,  which involves partially lifting the emulsion off the photographic paper  and manipulating it to create a veiled, three dimensional effect when  returned to the paper.

Instead of film, photographic paper can be used in a camera. This  provides a negative of limited tonality, (when printed, reds will appear  darker and blues lighter), which can then be printed as a positive in the  darkroom or scanned and printed digitally.

A photographic print produced without a negative. Instead, objects are  placed on the paper prior to exposure to light casting different shadows  to form a photographic image when processed.

Pinhole cameras form an image using a tiny hole instead of a lens.  The definition is always softer than a conventional lens; the amount  depends on the accuracy of the pinhole. Due to light passing through  in a straight line, an unlimited depth of field is possible; otherwise all  distances have the same relative ‘sharpness.’

Traditional black and white prints produced in the darkroom, printed  from negatives onto photographic paper and chemically processed to  give a stable, archival print. This is the conventional method for using  photographic paper.

A 19th Century process requiring the photographer to coat a glass plate  with collodion, sensitize with silver nitrate, expose and process, within  15 minutes. The resulting negative can then be printed conventionally  using the Silver Gelatin process or with a number of historic 19th  Century processes.
