BUG - Canon PowerShot G3
It's visible also on the camera LCD and it's produced in both
formats - JPG and RAW. So it's not depend on procesing computer
(PC) definitely - it's G3 series fault.
My 2 cents...that looks like a computer software issue with
conversion or something. Did you shoot jpg in the camera?
Now I'm surre that Canon G3 has production bug in case of direct
overexposed Sun shots.
You can check my pages:
I was in shop again and try new G3 - with same results.
I also test Sony 717 and Canon S45 - without problem. It's clear
that it's not issue of digital technology - IT'S G3 FAULT.-- hide signature --
this is, I think, one of those instances wherein a polarizing filter would come in handy.
