What happens when you try to import Raw files from the D7100? Any error messages?
When I try to open a RAW files, PS tells me it cannot open the file and
tells me to make sure I have the latest camera RAW update installed.
I have RAW v. 126.96.36.199 and when I ask to update PS, I'm told everything is
up to date.
That camera has been supported since ACR 7,4, so ACR 8.1 definitely does support it.
It would seem that your file is corrupted. What exactly is the wording of the error message you are getting?
Have you used any Nikon software to transfer your Nikon raw files to your computer? Nikon software is notorious for corrupting files during transport, especially if you're on a Mac.
That was the problem. I've been using Nikon Transfer, which came with an
earlier camera, to get the files off of the card and into the MacBook.
Turns out that was the problem. I copied them onto the machine using Finder
RAW and JPEGS are fine.
You're welcome. Glad you're all set.
