DIMINISHING OR ADDING VIGNETTING
Vignetting can be caused by a
mismatched filter/lens hood or a lens
(e.g., using a filter on an ultra wide

the frame).
To add or diminish a vignette:
Select the Lens Corrections tab 1.

Copenhagen with the Canon 5D
and is part of his ongoing series,

specic part of an image.
