Originally posted by tuco I been using Rodinal with RPX 100. And I've noticed my shadows seem to be more exposed than I expected with highlights on the edge. I decided to do a speed test. A speed test that places zone-one 0.10 density above base + fog and turned out to be EI 200. I'm Just wondering if you're experiences extra speed with APX 100?
I don't have the equipment (or skill) to perform tests like that. Offhand, I'd say that at 100ISO it doesn't achieve the same density as TMAX100@100 or FP4+@125, but has a higher density than Rollei 80S@80. Of course thats eyeballing it, so take it with an enormous grain of salt.
EDIT: I should add that the TMAX and FP4+ I'm comparing were with Xtol with times from the datasheets, the 80S was only with Rodinal with times and dilutions from the MDC, and the APX with HC-110 and Xtol, tims and dilutions from the MDC.
