Abstract

We propose an experimental and theoretical-mathematical methodology to characterize by spectroradiometric methods the spectral linearity of a conventional digital still camera. As the first step to this characterization, we have performed a test to verify the reciprocity law starting from the experimental and theoretic-mathematical characterization of the total spectral dynamic range of the relation between exposure and RGB digital output data. The obtained results show that the reciprocity law in digital photography is not exactly verified.
