An imaging apparatus comprising: A spatial light modulator ( 30 ) operable to receive incident light ( 34 ) representing an incident light image and to intensity modulate said incident light to form spatially modulated ( 38 ) light; and an image capture device ( 42 ) operable to receive said spatially modulated light and to detect an intensity value for different portions of said spatially modulated light to form a modulated light image therefrom; wherein said spatial light modulator attenuates different parts of said incident light by different proportions such that intensity values of said incident light image are given by a combination of intensity values of said modulated light image captured by said image capture device and data representing proportions of attenuation applied to corresponding parts of said incident light image by said spatial light modulator.
