How long do you think it will take Adobe to get PS Raw updated for the D850? What do you use for your evaluations before that happens?
DIGLLOYD: I have a query into Adobe as to when ACR might support Nikon D850 NEF raw files, but it is the weekend as I write this, so I don’t expect a reply until Monday August 28 at the earliest, and my usual contact is on sabbatical.
