Lightroom vs darktable RAW to HDR development color accuracy
HDR images best viewed on an HDR capable device + browser. Recommended setup: Macbook Pro 16 with XDR display + Google Chrome.
An HDR YouTube video was displayed on the M1 Macbook Pro 16 and the Panasonic Lumix S5II was used to take a photo of the screen. The raw files were then converted into HDR AVIF by Lightroom 14.2 (Camera Raw 17.2) and darktable 5.0.1. You can download the raw file here. The settings used to develop the photos will be given at the end of this post.
Zebra indicators on the S5II and raw overexposure indicators in darktable confirm that no overexposure is present.
The image from Lightroom appears desaturated. A discussion has been created on the Adobe forum https://community.adobe.com/t5/lightroom-classic-discussions/wide-gamut-hdr-colours-are-desaturated/m-p/15352803. It may very well be possible that I am unware of a setting in Lightroom that avoids the desaturation. If you have any ideas, feel free to add to the discussion on the Adobe forum.
