Webb24 juni 2015 · The cosine fourth law applies a similar principal and states that as the angle of light hitting a sensor or film plane diverges from the centre outwards (i.e. diverging from perpendicular to the plane) illuminance is reduced by a certain factor. That factor is the fourth power of the cosine of the angle that the light makes to the perpendicular.
