vignetting - what is

Is this possibly where one might add too much to the front of the leanse an cut out some of the view? like a bad hood or something. If not, what it is?

Yes, its the shadow around the corners and edges of a frame, and may occur if you stack filters or use too deep a hood.

Thank you for the confirmation, and thanx for the site, that was pretty informative with very good visual demonstrations.
