Formulary's Film Developer 23 is a metol-based semi-compensating film developer similar to Kodak D-23. The developer produces negatives with low to medium contrast. Developer 23 is the favorite of Zone System users. Four rolls of film can be processed in 1 liter of Formulary 23 without replenishment. With replenisher (Formulary DK-25R, 01-0057) a total of 20 to 25 rolls of film per liter can be developed. The chemicals in this kit are used to make a working solution with a shelf life of 6 months.

I'm a lover of history, well more like obsessed with it. Plus add in my love of trying out new old things from shooting a black powder musket, to using one of the simplest and a historic developer. Developer 23 is a must try for any home developer, produces amazing negatives with tone separation and surprisingly fine grain. While some films you have to shoot a little slower than box speed, it does give a very historic look. This certainly will be added to my kit with my WW2 era combat photographer impression.
