Hello,
(using RT 2.3c)
I want to posts these images to suggest that something has to be done if we want to use these features when we have red lights:

original image:

it is quite faithful

chroma NR 5:

reds turn to orange

luminance highlight recovery

whats happening with the reds?

color propagation highlight recovery

there is a hole in the image!

now is that normal?

Hello,
(still using RT 2.3c)
now I wonder whether no one took interest into that previous message maybe it was something stupid, but as it is close to this topic, I suggest something else:

Is it possible to retrieve overexposed image data before the exposure compensation is applied? In this way we would not lose the highlights like in this example here:



So applying positive exposure compensation means that the highlight recovery tool won't recover data that was previously there in the original non compensated image.

I know one way to avoid that is to selectively raise the shadows in the "Shadows/highlights" to avoid highlight clipping, but it's not that convenient, and I'm not sure the results are so clean (though I technically do not know how it is handled).
