I'm basically using a decent old 6x9 folder, and after a bit of testing I can use HP5 rated at 320(ish) with the camera on a monopod and a lens setting of 1/25 @f11-16, sometimes with a contrast filter sometimes without. These negs dev'd in Rodinal 1+50 are just how I like them. Problem is though winter is on its way with a drop in light of sometimes up to 2 stops. I need to use the f11-16 setting (tessar lens and DOF) and 1/25 is as low as I can go - I know, use a tripod etc, but I'm on a 'light as possible' mission so the monopod stays. I thought of rating HP5 round the 640 mark and using Rodinal 1+50 for maybe 10 mins with normal agitation, and then a 10 mins stand. Does this sound daft! Thoughts welcome on a technique for extracting a sharp, tonally 'normal' landscape image from HP5 and Rodinal at a higher than 400 rating, given that grain is much less of an issue than it perhaps should be. Is Rodinal the one? I could use D-76 in all its various dilutions. Pushing films is something I know little about, I'm more used to a lower than stated film speed with an adjusted dev time.
