True.  If I recall correctly, Daren's was not designed to model any physical
film or eye response.  However, the way in which it was implemented might be
good to notice.  He implemented it by replacing the "gamma_correct" and
"clip_colour" functions in POV, instead of using post process.

Also keep in mind that the actual viewing of the image will be based both on
the functions used to convert the floating point value into a limited-range
RGB value AND by the gamma settings of the viewing device (LCD, plasma, or
CRT).  Of course, if you're printing to a device that is capable proper
color matching, then this could be a very useful feature for high-quality
realistic output.
