Good points on what light the film has been shot.

The numbers were taken from a photo.net post a while ago...I just packaged it in a nice 
PDF. Just how accurate are the numbers/films and who worked on them is anyone's guess. 

But at the very least the PDF shows Photoshop users is there is more than just converting 
RGB to Grayscale.
