A light diffusing means for a photographic enlarger adapted to be positioned between a light mixing module and a film negative carrying module, the diffusing means including a diffuser body member having a light inlet opening, an internal light reflecting and diffusing chamber of frustoconical form, and an enlarged light outlet opening. Light transmitting and diffusing disks are provided at the inlet and outlet light openings. A conical member with a conical light reflecting surface is positioned coaxially in said chamber and in spaced relation to said openings for regulating the amount of light intensity distributed in a radial direction towards the periphery of the enlarged light outlet opening, particularly to enhance the intensity of light at the peripheral margins of the outlet opening.
