About us

Welcome to “BW Formula” — a project initiated by “Atelierele Albe”. We are collecting and sharing analog black and white photographic formulas.

As we try to classify the formulas, the best way to find what you are looking for is using the search function. Do not use any dashes or dots, i.e. do not search Kodak D-72, as sometimes it is spelled D72, sometimes D.72 etc. Just search for “d72” :)

Safety warning

We must caution you regarding safety. It is advisable whenever one is mixing chemistry to take proper precautions. Always use protective gear (goggles, gloves, apron, etc.). Always be certain to work in a well ventilated area. Always have extinguishing devices at hand in the event of an emergency. Always have an escape plan if the need for a rapid exit becomes necessary. Keep an MSDS for all chemicals present as this will not only be useful in medical assistance but also for emergency responders in the case that something were to happen.
