The camera name mapping preferences allow you to define a value to be used for the {T8} and {T9} tokens for different camera models. This is useful when using different cameras or when the camera name stored in the shooting data is awkward (e.g. Canon EOS DIGITAL REBEL) or when several photographers are shooting with the same type of camera.
The list area at the top of the window shows the currently defined mappings e.g. the value of {T8} for images from the Fuji FinePix S3 Pro is mapped to "Fuji S3" and {T9} is mapped to "Fuji". {T8} and {T9} can then be used to specify the filename or download directory of downloaded images. For example the mappings shown in the screenshot could be used to sort images from different manufacturers' cameras into different folders using {T9} (Canon, Fuji, Olympus, Nikon etc.) and the values for {T8} could be used to prefix the filenames with the camera model.
To add a camera to the list either drag and drop an image on the dialog window using Windows Explorer or click on the "Add camera..." button and select an image. To remove a camera from the list first select it by clicking on its entry in the list then click on the "Delete" button. You can also add the current camera when using a card reader by pressing the "Add" button.
Select the "Identify camera using serial number, owner string or user comment" checkbox if you have more than one camera of the same type and wish to identify them separately. When this option is selected the camera serial number (Canon EOS digital SLRs and recent Nikon digital SLRs), owner string (other Canon cameras) or user comment (settable in some other cameras e.g. Nikon D200) is appended to the camera model name to identify individual cameras. For example, in the screenshot above mappings have been defined for two Canon EOS 1D Mark II cameras: one with serial number 0000200192 which sets {T8} to "1D2_1" and the other with serial number 0000225600 which sets {T8} to "1D2_2".
To edit the values of the {T8} and {T9} tokens for a given camera model either double-click on the item in the list or select it and then press the "Edit..." button. The values can be set to any valid Windows filename character. It may also contain another token e.g. {d} for the date.
