Cinematography - Spectral response of photographic audio reproducers for analog dye sound tracks on 35 mm film

ISO 20859:2005 specifies the spectral response of the photographic audio reproducer light source and receptor as a unit, including any optical filtering that can be interposed.

The analog sound track formats suitable for reproduction using such a reproducer include the cyan dye-only track (without redevelopment of silver) and both conventional and "high magenta" soundtracks (with redevelopment of silver).
