Could you please recommend development time for AGFA APX 100 in Rodinal 1:100 and 1:200. Could not find this info... What are the advantages of using high dilution? Thank you very much.

Eugene.

Jim Vanson gives a recommendation for this combo (at 1:100) on my web site (on the page for APX 100) at UnblinkingEye.Com. Higher dilutions are supposed to give better edge effects and gradation, and in my experience this is generally true. Vanson recommends reduced agitation to keep the high values in check.

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.
