Gaslight paper - Gaslight paper
|
Photographic paper for contact printing coated with a low-sensitivity emulsion using silver chloride as the photosensitive material.

It has about 1/30 to 1/50 the sensitivity of high-sensitivity chlorobromide paper (for enlarged prints). Its ISO sensitivity is P12 to P16.
