I was shooting at a farmers market, one of my images had this colour cast, yet images either side of this were normal. All comments gratefully received Thanks
looks like the sensor glitched, my guess is the a,g,m,r if it does it again might be time for a check up, esp as its only done it the once and gone back to normal
At first I thought that the sun had bounced off a purple canopy, then I did also considered this was the sensor. This occurred on my 5DIII body, I did a shoot at an event yesterday used my 5D IV as I cannot trust the 5DIII to do this again. Many thanks for your reply
