Calibration (CAL) Files
In order to use any images taken with your DCS 465 Camera Back, a “calibration” (CAL) file designed for your particular camera back must be present on your computer hard disk. Instructions in chapters 4 (Macintosh) or 5 (PC) describe how to install that CAL file. If several different camera backs are used, the unique CAL file for each must be installed to access images from each camera back; this means you may have multiple CAL files on your hard disk.
CAL files are required in order to display thumbnails or previews of images in the driver image window, and are required in order to acquire an image. If the CAL file is not on your hard disk, or not in the proper place on your hard disk, you will see a message specifying the name of the missing CAL file when the driver attempts to display the image, and you will not be able to display or acquire the image.
When you copy or move images from a PCMCIA card to your hard disk with the COPY TO FOLDER or MOVE TO FOLDER commands, the CAL file(s) associated with the camera back(s) used to take the selected images are automatically copied to the folder with the images. The calibration files are needed subsequently to display and/or acquire the images. Therefore, do not delete any CAL files you find in folders with your images.
If you transport images to another computer (you may be distributing unacquired images to a different location at which the software driver is installed), be certain that you transport the CAL files found in the folder with the images. You will not be able to display those images, nor will you be able to acquire those images, unless their associated CAL files are available. Place the CAL files in the same folder as the images.
The calibration filename is your camera back serial number followed by a “.cal” suffix. For example, if the serial number of your camera back is
