A relay lens system for a high dynamic range projector is provided. The relay lens system comprising: a light input; a light output; one or more lenses configured to relay light from the light input to the light output; and, an aperture stop configured to provide a given numerical aperture to the light being relayed through the one or more lenses, the combination of the given numerical aperture and the one or more lenses are configured to introduce a spherical aberration in the light between the light input and the light output, the spherical aberration changing a shape of a pixel in the light from an approximate square shape at the light input to a function having an upper boundary and a lower boundary based on a distance from a center of the pixel, and a pixel dimension of a dither pattern in the light entering the light input.
