Forte distorsion des couleurs (dominante rouge impossible à corriger avec la balance des blancs) lors de l'importation de diapositives scannées. Ni le scanneur -Minolta Dimage, ni le logiciel-Vuescan- ne sont en cause puisque les numérisations sont de bonne qualité. Au demeurant l'importation dans Lightroom classic se faisait normalement jusqu'à aujourd'hui.

Quelle peut être la cause de cette aberration et comment y remédier?

Suggest posting one of the scan image files with the issue to Dropbox or other file sharing site. We can see how it behaves on our systems.

Here are the files: one is the scanned raw file, the other the same image after transfer to Lightroom.

The reddish hue appears only on raw files, JPEG are OK. Any clue?

Both the raw0028.tif file and raw0028.dng file look the same in LrC with over-saturated reds. How was the DNG file created and how was the tIF file created? If I look at the DNG file using XnView image viewer it appears correct with no over-satruated reds. I believe XnView is showing the embedded preview. I also tried RawDigger, which uses the raw image data and it appears correct without over-saturated reds. The DNG file has an embedded color profile, which appears to be causing the issue inside LrC and Camera Raw.
