Martin,

on that same note: try stand development when you use Rodinal 1+100 
with HP5+.  I know you experimented with stand development once, and 
that made made me curious. I tried a few different EIs and 
development times and found shooting at 800 and developing for 75 
mins at 20°C gave the best results. Ninety minutes (sixty minutes) 
give a one stop denser (lighter) zone 9 than  75 minutes. I agitated 
for the first thirty seconds, and then for about ten seconds about 
halfway through. Very convenient. Except for more shadow details, the 
results were not much different from regular small tank development 
results. Stand development results with Delta and Tmax films were not 
good.

I shot a lot of Kodak grey cards when testing HP5+ in Rodinal 1+100. 
Not a single spot, although they should be easy to spot (pun 
intended) on smooth grey negatives of different densities.
