The wingspan of a Snowy Owl is quite impressive - an average of about 1.5 yards, with males a bit shorter than females.
Canon 5D Mark III with my 500L f4 lens handheld @ 1/1000, f16, ISO 400 with no exposure compensation.
Cropped slightly for composition purposes. Toned down the cyan tint due to a late afternoon setting sun a bit just on the owl without affecting the back and foreground.
Cheers,
Mike
