Light gives energy to electrons in the photographic film. Some of these electrons find their way back to silver ions, transforming them back to atoms.
The ions leave its correct lattice site and occupies an interstitial site but silver atoms are not colorless. They are black. So, a photographic film exposed to light turns black at every point where light strikes a silver ion.
