Right I re ran the calibration software and its still fine thought might have to do with different light in room this time of year but all appears fine, no 1 tiny tiny pieces of his tail are being warned to me via the highlight warning, and no 2 under chin which I was aware of anyways my fault with that for not paying attention when taking the shot lol.
I'm not picking up blueish tinge here well except for the colour that is on them within the white the grey colour but that is actually on the squirrels some have more than others, and sometimes this lot from the area I go have a lot of red on them, there is a black one there also but hes proving to be a git to capture and believe me I am trying lol.
Im a massive squirrel fan myself adore them and could spend ages just watching them scampering about, sounds like you have had a bad time with them Barry?
