As a side note, to prevent rumors from spawning: It's not "my" gang of 
programmers; the "leader of the pack" is still Chris Cason, I just 
happened to have more time than others to plow through POV-Ray code in 
the recent past ;-)

At present, there is no support for simulating photographic film 
exposure built into POV-Ray 3.7. Maybe misuse of the output gamma 
handling mechanism might get you comparatively close. My personal 
suggestion would be to output the image to some HDR format (i.e. either 
OpenEXR or Radiance HDR), and apply a suitable tone mapping curve as a 
post-processing step in Photoshop, Gimp or what-have-you.
