Wow, what a lot of reactions on one day.  Seems I've touched a few
people's hobby here.
Summarizing :
1) Shawn : the web page link for pushing HP5+ up to 3200 : I've seen
this one, but since I only have Rodinal at the moment, I only checked
that part of the table (which goes up to 1600).  It *is* very
interesting, but I was kind of looking for 'general push experiment
guidelines' or maybe a few curves like the contrast- and the
temperature-development time curves.  BTW : for T-Max3200, the list goes
up to 25000 ASA !  That's nice for a start :-)
2) Lars : I've got a place (my kitchen which is a narrow U-shape) that I
can use as a controlled scene.  I knew the contrast would go up, but I
didn't know why.  I didn't know about the chromium intensifier.  Sounds
interesting.  Thanks for the lesson !
3) Gene : on one side, I'd like to stick with Rodinal because I'm using
this already for my evening classes in photography (where we calibrate
our development process).  On the other hand, now I'm deviating anyway
...

I think I'll be starting with my regular Rodinal, using the 50%
time/stop and see what the result is.  Unfortunately, evaluating on
prints is a bit harder for me because I don't have an enlarger (and
doing it during the hours of the evening class isn't always possible, of
course).  I'll buy myself a good enlarging lens for studying the
negatives and if that doesn't work, I'll have to do the printing anyway.

What the purpose of all this is ?  Well, just experimenting.  If the
effect is graphically nice, that's fine.  If I can just shoot pictures
of the Pleiads with my 300mm/f5.6 without a tripod, that would be nice
too (astrophoto pun : that's a few minutes exposure normally).
