I apologize for the fact that this has surely been posted before and I haven't bothered to find it, but here goes. I would like to hear from anyone who has been push processing either PMK Pyro, WD2D+, or Rolo Pyro developer for sheet film. I'm using pyro developer for my 8X10 negs and currently shoot FP4 and HP5, but would consider switching to Delta 400 or Foma 400 if it's a better match for push processing. I would like to push 400 iso to 800 or more with these pyro developers. I use BTZS tubes for both 4X5 and 8X10 but could switch to tray development for my 8X10 stuff. I'll be contact printing with P/P and under exposing to get a higher iso with push processing. I've looked over the massive developing chart on Digitaltruth and can't find what I'm looking for. Anyone with experience with times and temps let me know. Thanks.
