However, it's possible that aluminium hydroxide might be indirectly involved in photography through certain processes. For example:
* Papermaking: Aluminium hydroxide is sometimes used in paper production, which is then used for photographic prints.

If you have a specific photographic process in mind, providing more context could help clarify its potential involvement.
