[pure-silver] Re: Developing Plus-X in Rodinal 1+100

Hi,
The problem is that the Massive Development Chart doesn't give a recommended time for PX at 125 iso or 64 iso in Rodinal 1+100.

Hi,

I'm planning on shooting some 120 Plus-X at the rated 125 iso and I want
to develop it in Rodinal 1+100.  I checked the Massive development Chart
and it gives 6 min for Rod 1+25 and 13 min for Rod 1+50.   What would be
the extrapolation for the time if I developed in Rod 1+100?   I figure a
ballpark time of around 18-19 minutes.  Does somebody have a more
precise time?

In passing, is 125 iso a good starting point or should I be shooting
with a lower iso, say 64.  Haven't used Plus-X since high school in the
60's, so I am unfamiliar with what I assume is an updated version of
Plus-X or has it stayed essentially the same emulsion?

Any info about Plus-X would be appreciated, pros and cons.

Cheers,
Bogdan



I shoot PX at ASA 64, and develop in HC-110 or D-76 or PMK Pyro
depending on the subject.  In all cases - assuming your thermometer
and timers are OK, start with a dev time about 20% shorter than
recommended.
