Amusing to note that the shutter speed (1/256) is shorter than the exposure time (1/250). Also, what is the "aperture value" of 6.5 mean; the f-stop is given as 9.5.Incidently, with focal length of 10 mm, then the aperture diameter would be 10mm/9.5 or a hair bigger than 1 mm.... quite a small aperture.
