Well done, it’s about time, under the right circumstances this can be hugely useful.
Huge time savings in post-production — In-camera RAW batch processing
Shooting in RAW gives greater leeway in post-production, letting photographers draw the most from the images they capture. Until now, however, processing RAW has always been extremely time consuming.
The D850 resolves this issue by offering an incredibly convenient, in-camera RAW batch-processing feature, which enables you to quickly apply the same adjustments to selected images.
You can save the original RAW files and processed JPEG files on one large-capacity XQD card, or else save the original on XQD and the JPEG on an SD card in the second slot, for easier data management.
It’s about time, under the right circumstances this can be hugely useful. Regrettably it seems to be JPEG only (no 8 or 16-bit TIF).
Interesting that Nikon references Lexar Professional—discontinued.
Why Nikon publishes blurry hardly readable screen shots in the brochure, I dunno.
