Didn't know whether to post in this forum or the Adobe forum, but here goes.
I've just discovered that I can't open my raw files from my D4 in Camera Raw or directly in PS. I'm on a Mac, using PS5 and ACR 5.0. I've read that this is a known issue but I can't seem to figure out if the fix is available yet. Does anyone know?
There's a very solid 6.7 release candidate available at labs.adobe.com. It supports both the D4 and D800. I've used it for quite a while with no problems, and Adobe's history with release candidates is quite good. http://labs.adobe.com/technologies/cameraraw6-7/
