Panchromatic films, Orthochromatic films, IR films, UV films; each requiring Folks have been trying to figure out which filter to use to properly interpret to their intentions for the scene for as long as B&W photography has been available. Using CCD and Cmos chips simply bring up their own spectral response and require proper filtration whether by the manufacturer supplying a filter over the chip or deciding not to (in the case of Leica M8). Not hocu pocus - rather science - and art depending on your interest.
