I don't know if I'm in the right place for this question however I would be very grateful for any help on this. I seem to get interior and exterior shots that often have very pink highlights and I can't figure out why (see attached). I'm using a Canon 6D Mark II, AV mode, ISO 320, F-8 and AWB, no filters. Thanks so much
I had a pink cast from my Sony when using AWB in the garden. Changed it to shade or sunny as applicable and the cast disappeared. It may be the lighting you have that is the problem.
Make sure you shoot in RAW and then you can change the white balance setting in post to get the image colours correct.
