I tried D-23 extensively, especially with 100 ASA films. I found that it is a fine grain developer with average sharpness and some loss of speed. After Ryuji published his DS-10 formula, I tried it and found it plain better than D-23 with suitable films (I had good results with the Deltas, T-Max, Acros and 400TX and not-so-good results with APX and Lucky films). DS-10 1+1 is my standard developer for my standard films, Delta 400 and 100, I use if for about 90% of my work. OTOH, I love APX100. So I looked for a fine grain formula for it and tried a Microdol/Perceptol lookalike from the net (or Anchell-Troop?). 5g Metol 100g Sodiumsulfite 33g NaCl (iodide free, not plain table salt!) 1g Boric acid dist. water to 1l solution My results (used 1+3 with APX100) are very good, I rate it at 40 ASA and got extremely fine grained and sharp results. My dev time is 11:00 at 24deg in a ATL3 (75 RPM).
