I just shot a newborn session on my brand new Nikon D810 and my RAW files will not open in ACR or CC or PSE. Everything is up to date. This is my first time using the new camera and the photos are for a paying client. Am I screwed until the new ACR updates are released? Or is there some magic fix until then? I'm panicking!
Every new camera comes with its own specific Raw file format and Adobe must add support to Camera Raw for each individual camera released on the market. There's often a time lag between the camera shipping and Raw support being added to Camera Raw.
Lots of D810s are now in circulation (dozens of D810 Raw support requests have popped up in these forums recently) and Raw support from Adobe is imminent but not yet final.
D810 support has just been added to the yet-to-be-released Camera Raw 8.6.
Adobe has made the Release Candidate version (a kind of post-beta, pre release) available for further testing prior to final release.
Install manually but use at your own risk until final release.
