I have some JPEGs shot on a Fuji X100F. They're high contrast, shot in Caribbean sunshine.
The blacks show up as blue patches in CC Classic (updated). Normally, with RAW, I can sort this with the 'blacks' slider but even at the extreme right of the scale, the blacks are still showing patches of blue.
Can I fix this?
Sounds like you have the clipping indicators turned on (blue for shadows, red for highlights).
Press J to turn them off, or click the triangles in the top corners of the histogram.
Thanks. You are my favourite person of the day.
