I'm using a Nikon D1X. This camera shoots natively at 6MP, but it it possible to get 10MP files at Raw processing. For example, Nikon Capture allows to choose if you want to open D1X files in 6MP or 10MP, and some other RAW processing softwares opens directly the D1X NEF files at 10MP.
However I've not found any option for this camera in Camera Rax. The NEF files are opened at 6MP only. Just like for other files, it is possible to ask for a larger size, but that doesn't seems to use the special features of the D1X captor.
Has somebody experience of the size handling for D1X in Camera Raw ?
