the bromoil process was an early photographic process that was very with the pictorialists during the first half of the twentieth century. the bromoil process was based on the oil prints, who origins go back to the mid-nineteenth century.
the prints are made on paper with a thick gelatin layer that has been sensitized with dichromate salts.
after exposure , the print gets soaked in water. the non-hardened parts absorb more water than the hardened parts, so after sponge-drying the print, while still moist, one can apply a lithographic ink to the oil-base. the non-mixing character of oil and water results in a coloring of the exposed parts of the print, ceasing a positive image. the ink application requires considerable skill, and as a result no two prints are alike.
hand printed fotos are like small wonders, like a birth, the result is always a surprise
