@priort

older methods are based on WB ie the notion of HL going to white where as the modern wb uses a CAT to produce or correct for an illuminant and that is not white

That’s not quite what causes the difficulties with color calibration. The strange colours (blueish) appear because the white balance is changed after the highlight correction module sets the blown regions to white (based on the white balance module’s settings). Those whitened regions then react like any other white region when you change the white balance to a lower color temperature: they appear cooler, i.e. shift to blue.

Inpainting methods don’t force the blown areas to white, but try to derive the “correct” colours from the areas around the blown areas.

@Terry

I want to directly compare one day the inpaint and RIC. Are they fundamentally aiming to achieve the same sort of fix?

Well - both try to do something on blown out color channels The way they work is completely different …
