It's both. A base to develop the image, followed by a weak acid to halt the further development of the image.
The Ilford developing chart provides information on developing times and techniques for different types of Ilford photographic films.
It utilized self-developing photographic film.
Acid + base conjugate base + conjugate acid
Acetamide is a weak base. It can undergo protonation to form the conjugate acid, acetic acid, in acidic solutions.

A Brønsted-Lowry acid-base reaction involves the transfer of a proton (H+) from the acid to the base. The acid donates a proton, while the base accepts a proton. This results in the formation of a conjugate base from the acid and a conjugate acid from the base.
The base which a certain acid turns into.Every acid had a conjugate base:HX (acid) X- (conjugate base)The acid is also called the base's conjugate acid.
An acid base imbalance can result in
acid. you can actually run batteries off it.
Acid + base salt + water
In a Brønsted-Lowry acid-base reaction, an acid donates a proton (H+) to a base, which accepts the proton. This results in the formation of a conjugate base from the acid and a conjugate acid from the base. The overall reaction involves the transfer of a proton from the acid to the base.
Photoflo is a soap-like chemical used to wash the developing chemicals off photographic prints and negatives.
