Annotation	In virgin Ge6As43S35Se16 amorphous film we observed an absence of phot-induced optical gap shift induced by white light illumination. We found red shift of the optical gap induced by illunination with over-gap photons and blue shift by illumination of the darkened state of the film with sub-gap photons. It is supposed that simultaneous action of over and sub-gap photons, present in white light, result in observed photo-insensitivity of this film for white light.
