    Posted by on 4th Mar 2020

    D-23 in devided developmet with Sodium Metaborate as the second part has been my go to developer since the eraly 1970's.

    It produces wonderful, fine grain negatives.

  2. Classic Fine Grain Developer 5 Star Review

    Posted by on 17th Jan 2018

    Used to mix it up by the gallon, back in the day, and thought it was great with Kodak Panatomic X--especially in 35mm. Being a solvent developer, I wouldn't use it with the current weapon of choice, Acros 100. Looking at the Dark Side of staining developers to see if I like the results. D-23 is still the go-to for many in large-format, especially with traditional grain films like Ilford's and Fomapan, among others. Doesn't have the high acutance and razor sharpness needed for 6 x 6 and smaller, maybe D-76, or some of the newer formulas--especially for t_grain films. Enjoy!

  3. A wonderful developer - Simple and Effective 5 Star Review

    Posted by on 28th Jun 2016

    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.
