Preston,
I do agree with your reply; but I think that your articulation might be
clearer if you had said: "Most people recommend resampling before
sharpening" instead of "Most people recommend resizing before sharpening"
since resizing and resampling are two distinct operations which are not
necessarily connected. Resizing without resampling only changes the
effective resolution but not the acutal resolution; whereas resampling
changes both. It is the latter that impacts on the results of USM - not
the former.

-------------------------
If the pixel count isn't changing, then you aren't changing anything in
the file. "Resolution" just tells a printing application the "print
size" of the image. Most people recommend resizing before sharpening,
since sharpening is dependant on output size and output method (inkjet,
screen, offset print, etc.). Bruce Fraser has a good three-phase
sharpening procedure he outlines at
