Attached is a screen shot showing the same .CR3 file, from a Canon 90D, open in:
top left - Affinity Photo v184.108.40.2061
bottom left - Canon DPP v220.127.116.11
right - DxO v3.2.0 build 4344
No explicit processing has been applied in any of the Apps, they are all what you see on first opening the file, i.e DxO is applying its standard preset.
The version in DxO has an obvious yellow colour cast.
Anybody from DxO care to comment?
