FormulasThis formula is a universal developer for all projection and contact papers. It gives rich black tomes with excellent brilliance and detail. Ansco 130 provides unusual lattitude in development and is clean-working even with long developing times.

The prepared soick solution is clear but slightly colored. The coloration in this case does not indicate the developer has deteriorated or is unfit for use.


For use, dilute 1 part stock solution with 1 part water.


Normal developing time at 68F (20C) for Brovira, 2 to 6 minutes, for Convira, Cykon, Cykora and Indiatone, 1 1/2 to 3 minutes.


Greater contrast can be obtained by using the developer stocker solution full strength. Softer results can be obtained by dilution 1 part stock solution with 2 parts water.


(Ed. Note – While the papers mentioned are long gone, this developer still works well with modern papers. Most folks mix it, then dilute 1:1 and store that as their working solution. Many report it keeping nearly a year in glass bottles. Thus, it’s very economical. Also. Some folks use it diluter 1:10 or so as a film developer.)
