When I shot portraits commercially back in the early 70's I always used FP4 in ID-11, using natural light and a Pentax Spotmatic F or Mamiya C33. The ID-11 was replenished which gives results more like using it at 1+2 or 1+3. In low light I used HP5 but only if I really needed to.

Shooting rock bands, on the odd occasion where I shoot film I generally use Tmax100, sometimes 400 and process in Xtol, again replenished, although more recently I've started processing nearly all my films in Pyrocat HD.
