Yes, I remember reading those posts Moose. But this pattern (at pixel
level in Photoshop Elements) looks like a regular pattern in an area of
little detail (a white flower). I will have a go with my enlarger and
see what I find. I use a grain focus-finder gadget so I should be able
to recognise the pattern if it is the same.

You know, all the recent posts about the Nyquist theorem, sampling
rates and film scanners has made me think again that certain
film/scanner combos can result in what appears to be excessively large
grain, but is really aliasing. It would be interesting to know if your
wet prints show the same size grain or not. I get very fine grain from
iso 400 color neg film on a 2720dpi scanner and I can't imagine your
B&W is worse than that.

But the scanner found the grain pattern in the Neopan quite easily
(developed in ID11 1:1 for 8:30 at 21deg C); I wonder if HP5 would
have been quite so grainy.
