Abstract
Many digital cameras now have an option of raw data output. We first show, by way of superposigrams, that this raw data output is quantimetrically (i.e. in terms of the camera´s response to light) linear, in the case of the Nikon D2H digital SLR camera. Next, we perform comparametric analysis on compressed images together with their corresponding raw data images in order to determine the camera´s response function.
