I don't pixel peep, the colour cast is actually rather apparent after taking the photos... I'll post a photo here when I get home...
no no no, i meant.. for c omparing difference between nd400 and nd110, i have used both, but i don't pixel peep
the color cast is one reason why you see most of my nd110 photos turning out in bnw..
of course, raw can help, but long exposures have that special charm in monochrome, somehow.
