I shoot a lot of HP5+ in that format.
I love perceptol but it's very expensive.
I use to use DDX 1+4 with HP5+. But even that seemed too pricey, so I
went back to D-76. I'm satisfied with the look of the prints: not
grainy, good tonality. With a high SBR, the development time would be
less than normal, so there would be even less chance for too much
grain. What is the paper scale? Mine is usually 1.2 with a diffusion
enlarger on Ilford warm tone paper.
I'm not sure what acutance is.

Hi folks,
I am about to develop a roll of HP5+ (120 format) and I need you to
help me settle on a choice of developer. So Initially, here are my
observations and requirements:
1 My scene contains a landscape shot with a Subject Brightness Range
(SBR) of about 8-9 stops.
2 I would like use a developer which will provide very good
acutance.
3 I think I would like linear tonal separation over the SBR of the
scene (let me know if that requirement will not result in subjectively
pleasing results).
4 I'm not too fussed about minor to moderate differences in grain
size because print size will be no more than about 11x14inches.
5 I think I have narrowed down my developer choice to either
Perceptol or XTOL.
Can people help me decide between those two developers which will
optimise points 2 and 3 above? (Or even offer another suggestion -
e.g. I also have some 510-pyro to make up).
regards
Peter
