Hi Chuck,
Yes, it's very common to use centre filters for all wide-angle large
format
photography, unless you really want extreme dark corners for effect,
or if you're
not shooting colour slide film, which means the darkening is often
corrected during
printing or digitally post-scan.
I never shoot my 6x17 camera without the centre-filter (well, I did
last weekend for the
first time, still have to see how the images came out).
