when i open a picture taken with the new Nikon D800 neither LR nor PS show the profiles i can see with the pictures taken from the D700. This also doesn't work when i convert them to dng with the beta version 6.7 of the dng-converter.
My workflow uses the x-rite colorchecker to generate profiles. It wouldn't be nice if this will not work any more.
new picture old picture (no changes in program configuration)
The support for th D800 is beta so I'm pretty sure you'll only have Adobe Standard. You should be able to make your own profile for the D800, the D700 profiles won't work–different camera. When the final version of ACR 6.7 ships I would expect it to have some additional vender matching profiles as well.
When you make a new profile you need to open a DNG file in DNG Profile Editor. That DNG needs to be from the same camera model (eg, D800) that you intend to use the profile with. Otherwise your new profile won't show up when you process your D800 images.
Thanks to all answerers,
i think in my first try i did something wrong (didn't check wheter the file was actually created in ..\roaming\adobe\cameraraw\profiles).
The rest was confusing about the camera dependency of the profiles.
Everything works fine now.
