Recent Master lets image turn black when COLOR CALIBRATION set to iluminant "As shot in camera"

Software darktable
1

Hi,

I just compiled recent Master (4.3.0+1529~gdff4b30a22) on Ubunto 22.10.

As soon as I have COLOR CALIBRATION set to iluminant “as shot in camera”, the image turns black (EOS R7 CR3 Raw files),

White Balence is set to “Camera Reference”. Any other setting for iluminant looks ok.

Any ideas what might happen here?

Thx, Martin

First thing to do is look at the commit log on github: Commits · darktable-org/darktable · GitHub

I’d say that 084bf73 looks like a strong candidate for causing something like this.

I see the same thing. I have built from source and I am on same commit release-4.3.0-1529-gdff4b30a22.

I have not yet analyzed fully, but if I reset history and go back to default I get a black frame in darkroom. As soon as I disable color calibration I get the picture rendered again.

Edit: I use Canon 5D mk IV CR2.
