A photometric measurement apparatus, includes a digital video camera for generating digital data representing the image of a scene of interest, a device for stepwise changing the exposure duration of the camera; a device for controlling the camera to create automatically a series of digital images of the same scene over a range of different exposures; a device for storing the digital images; a device of assembling data from the series of digital images to create a single composite digital image containing information from at least some of the digital images and representing an intensity dynamic range greater than that obtainable from what can be measured from any single image; and a device for storing said assembled data representing said composite digital image.
