Looking for raw photo

[nwinspeare (Nicolas Winspeare)]

Hello,
I am experimenting with the color calibration module in darktable 3.4
I watched the video produce by Aurelien Pierre showing how to process a photo taken with powerful blue led lighting and I would like to try.
Does anyone have a raw file I could play with (privately) to try gamut compression in darktable compared to what Lightroom and C1 can do?
Thanks,
Nicolas.

There are plenty of play raws that have tricky light conditions that you can use.

Thanks,
I didn’t know about play raw !

The Nut Playraw was particularly helpful:

Deliberately difficult gamut colors in macro shot of hex nut

As a companion example to this topic I created, View/Modify color matrix in DCP files , I deliberately shot this extreme macro of a hex nut, 1/4" by 20, lit by incandescent bounced off a slightly yellow ceiling, with a background of pure blue (rgb 0, 0, 255) displayed on an LCD monitor. I had to export as tiff with tamed gamut, and then do curves on that tiff before export, hence me sharing two sidechain files used to get to the final jpeg shown. Have fun, and feel free to use this in any so…
