Opening the back and looking through the corners with the shutter 
open is a lot more accurate, besides being cheaper and faster, than 
taking shots.

It's very easy to see when a hood or filter impinges on the rays that 
go to the corners, even when the result may be missed on anything but 
a truly evenly lit, featureless surface.
