Hi Ed,

Certainly if you are going to do "major" (what ever that means) tonal
corrections, yes...but I'm skeptical that you will do any significant ones
from just cropping.  Upsizing shouldn't warrant any tonal corrections just
because of the upsize, but of course, that depends on how good you did the
tonal corrections in the first place.

I guess I wouldn't normally suspect you would do anything major just because
you cropped, but that certainly is a judgment call.  Typically, cropping is
just re-composition, and is really cropping a very small portion of the
image, and therefore there wouldn't, for me, be any tonal corrections,
unless I didn't get them right in the first place.

Regards,

Austin
