I got a Nikon D80, but when using camera fixes in Photoshop CC 2015, it does not exist
The oldest Nikon DSLR is Nikon D90.
I have Photoshop CC 2015.0.0 and Camera RAW 22.214.171.124
Maybe they decided to delete the old cameras or something? In this case, is it possible to add the camera data from CS6 / to an online repository or similar?
