But bromine, iodine, chlorine, and silver could not fix an even greater failing of early photographs, their impermanence Good pun.

Good pun.
- syncsynchalt 5y agoI have to guess a little at what you mean. My guess is the word "fix", having only been tangentially involved with photography are these the chemicals that we now call "fixer"?
- aaronbrethorst 5y agoFixer is a class of chemicals used in wet photography to reduce impermanent, light-sensitive silver ions to permanent metallic silver.
- seszett 5y agoThat is actually done by the developer. The fixer washes away the remaining unexposed silver ions that were not reduced to metallic silver by the developer.
- aaronbrethorst 5y agoAh, so it does. The fixer stabilises the image, removing the unexposed silver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image https://en.wikipedia.org/wiki/Photographic_fixer https://en.wikipedia.org/wiki/Photographic_fixer
