Thanks for trying anyway!

The 'latest' release - if there ever is such a thing  :-) 7.5.

It's a bit annoying because I sometimes want to batch scan a pile of images 
with a slightly clipped black point to get a fairly contrasty result for 
previewing.  But the introduced grain/noise/whatever (and it is often a lot 
worse than my example) stops that working well.

When I get the scanner out again, I'll try using its software and see if it 
gives the same result, in which case I won't blame Vuescan and annoy Ed when he 
returns from holidays..   ;-)
