What it is

The bromoil process is a fine-art photographic printing method that bleaches a silver-bromide print and then impregnates it with oil-based pigments, allowing manual intervention in the image. It was developed by Edward John Wall and Charles Welborne Piper, and was widely used by pictorialist photographers in the first half of the 20th century.

What it led to

  • Key tool of pictorialist photography
  • Manual, artistic intervention on the photographic print
