Calibration (CAL) Files —
EOS•DCS 1 Only
In order to use any images taken with your EOS•DCS 1 Camera, a “cali- bration” (CAL) file designed for your particular camera back must be present on your computer hard disk. Instructions in Chapter 4 describe how to install that CAL file. If several different cameras are in use at your location, the unique CAL file for each camera must be installed in order to access images from each camera; this means that 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 images from a PCMCIA card to your hard disk with the COPY TO button, the CAL file(s) associated with the camera(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. For this reason it is very important that you do not delete any CAL files you find in folders with your images.
If you transport your images to another computer system (perhaps you are distributing unacquired images to others at a different location at which the software driver has been installed), be certain that you also transport the CAL files found in the folder with the images. You will not be able to display those images in the driver image window, nor will you be able to acquire those images, unless their associated CAL files are available. The CAL files should be placed in the same folder as the images.
