Response to Development time APX 100/Rodinal 1:100

I use rodinal 1+100 for 20 minutes at 20°C with an EI of 50 asa. Agitation : during the first 30 seconds and at the beginning of every minute. This results in the following density values for zone I to X : I : 0,09 / II : 0,22 / III : 0,33 / IV : 0,44 / V : 0,63 / VI : 0,82 / VII : 95 / VIII : 1,16 / IX : 1,32 / X : 1,45 I like this combination a lot but negatives are too thin at 100 asa. For 100 asa I use 1+60 for 15 minutes. A combination which is hard to beat.
