The Working Space can be a calibrated monitor profile or Adobe RGB, or anything you want. The image profile is set when you convert from RAW, or if you shoot JPEG, then whatever the camera setting is.
FWIW: I set Camera RAW to convert the image to Adobe RGB, 16 bits, 300 dpi, whatever the camera's native resolution is, and no sharpening. After adjusting color settings in Camera RAW, and the image is opened in Photoshop, it will have an imbeded Adobe RGB profile. This is the image profile. The paper profile you choose in the Printer Dialogue Box is different and determines how the image prints. (How much ink, bi-directional/unidirectional passes, star wheel height, matte black, photo black, or quad black, etc.)
In the Photoshop Print Dialogue window, jmvdigital uses exactly the same settings that I use.
