Photographic Toner

Photographic toner is a type of chemical solution used in the development process of black and white photographs. It is typically used to enhance the tonal range and contrast of the image. Photographic toner works by reacting with the silver particles in the photographic paper, resulting in a change in color or tone.

There are different types of photographic toners available, each producing a different effect on the final image. Some common types of toners include selenium toner, sepia toner, and gold toner. Selenium toner, for example, can give the image a slightly warmer tone and increase its archival stability. Sepia toner, on the other hand, can give the image a brownish, vintage look. Gold toner can add a warm, golden hue to the image.

Photographic toners are typically used in darkroom settings, where the photographer can control the development process and achieve the desired effect. They are an essential part of the photographic supplies used in the development of black and white photographs.
