Gelatin Printing-Out Paper (POP)[edit | edit source]

Historical Facts[edit | edit source]

Gelatin Printing-Out Paper (POP), popular from the 1880s to the 1920s, was one of the first silver-based photographic papers used extensively. Unlike later photographic papers which develop out rapidly in chemical baths, the image on a POP appears gradually and visibly upon exposure to light and is then stabilized through toning and fixing. POPs were favored for their rich, subtle tonal variations and deep, warm blacks which were ideal for portraiture and landscape photography.

Identification Characteristics[edit | edit source]

Image material[edit | edit source]

POPs use a gelatin-silver process where the image is formed by metallic silver in a gelatin binder.

Color[edit | edit source]

The prints typically exhibit a range of sepia tones to rich browns and creamy whites, depending on the toner used.

Support[edit | edit source]

The support is generally a high-quality, heavyweight paper, coated with a baryta layer, often with a smooth, glossy surface.
