Has anybody experience of using Perceptol with APX 100? What are developing times and what dilution works best. ILford only give times for 1:1. How about 1:2 or 1:3? Also how about times if EI is reduced to 64? Thanks.

Those dev. times were given to me by a friend :

APX 100 / Perceptol 1+3,

N: 20min. (ISO 50) N+1: 30 min (ISO 64) N+2: 40 min (ISO 125) N-1: 15 min (ISO 40) N-2: 13 min (ISO 32)

All times are for development at 20 degrees Celcius, agitation every 60 sec. Negative contrast good for printing on a condenser enlarger. Have to be adjusted if you use a dichroic or cold light head. This is a starting point, you have to conduct your own tests to find the right dev. times for yous system...
