Hi,

I noticed somethin the other day when I closed my eyes for about a
minute or two under very bright sunlight and after I opened my eyes
everything looked bluish for a while until it went back to normal. The
same kind of thing happens in digital cameras. If you've ever set the
white balance of your digital camera to tungsten light condition, and
take a photo in bright light of day, your photo will have an overal
bluish effect.

I was wondering if these two are related and that's what happens with
human vision as well !

Cheers,
Michael
