Simply so, what are the three chemicals used in the darkroom?The three basic chemicals are (1) Developer (2) Stop Bath and (3) Fixer. Mix these with the appropriate amount of water and store them in your bottles. Photographic Paper. Photographic paper is sensitive to light and should be handled only in a darkroom with the correct safelight. what is film developer made of? The developer solution is comprised of a combination of chemicals, consisting of alkali and metol or hydroquinone mixed with water. The purpose of the alkali is to penetrate the protective coating allowing the metol to reduce the exposed silver bromide to black metallic oxide. Subsequently, one may also ask, which solution is used in photography? Ammonium thiosulfate. Fixation is commonly achieved by treating the film or paper with a solution of thiosulfate salt. Popular salts are sodium thiosulfate—commonly called hypo—and ammonium thiosulfate—commonly used in modern rapid fixer formulae.What is photo fixer made of?The original fixer is sodium thiosulfate which is customarily replaced by ammonium thiosulfate. Photo films and papers are coated with unflavored and highly purified gelatin. This is the binder (glue) used to affix the light sensitive material to the film or paper base.
