Perhaps someone would want to use a special effects filter (e.g., a
starburst), or a polarizer to cut down on reflections, or a graduated
neutral density filter to balance light levels across the image, or an
IR filter or IR blocking filter to enhance or reduce the CCD's
sensitivity to the IR portion of the spectrum.  These are all easier
to do before capturing the image.
