Hello all,

This photo, and approximately 10 others, was taken with the low sun roughly to my left, probably at 9 o'clock (angle not time) or south west on a compass. It has a terrible purple/blue cast to it as well as being over exposed. I was using a Canon 300mm F4 IS with the hood extended and is fitted with a protection filter which is a clear glass filter not UV filter.

As a contrast, this photo was taken from the same point only minutes earlier but I had the sun directly behind me...

Any suggestions as to what is up? Could the UV from the sunlight have been reflecting inside the lens hood? I didn't see anything wrong through the viewfinder at the time so I am suspecting UV.

Any suggestions welcome.
 
:agree: definitely a WB thing - shifting position is an easy way to trick a camera into coming out with the wrong result.

Yo're also shooting into a shadow in the Robin shot so this darker area will, in wintery, cold light, appear bluer. The perils of winter shooting....

Just looks like a white balance issue to me. Your WB is correct for the bird in the sun, but behind the fence is in shade, and therefore much cooler visually (higher K).

Overexposure could just be your metering being thrown off by the dark background, what metering / exposure mode were you using?

I was using evaluative and capturing in RAW. AWB was selected as I shoot both JPEG and RAW.
 
Giving us exif to look at would help. Overexposure - what kind of metering were you using? #1 looks like a situations for spot or centre weighted metering.

:agree: Should be fixable from the RAW. I think it's the small subject / large dark background - a different metering mode would have fixed this I think - pref spot. The exposure being out is maybe showing up the WB problem more - but in winter shadows are bluer.
