In the latest updates from Adobe, Lightroom CC 2015.3 and 6.3 for those on standalone versions, official support for Leica SL (Typ 601) DNG files has been added. Photoshop Camera Raw 9.3 is also available for update as well, offering the same support for those using Photoshop and Bridge. This is great news and perfect timing as the first Leica SL cameras are now making their way to happy homes.
When I first tried out the camera, the images looked very good in Lightroom, even without official support. Now, having reprocessed a number of files with the latest update installed, they look downright amazing. The biggest changes I see are the improvement of noise at high ISO, color accuracy when using the Adobe Standard color profile and a wider dynamic range. The files respond far better to highlight and shadow recovery as well.
Upgrades are available immediately at Adobe.com or by upgrading in the Creative Cloud app on your computer.
