Most people do not know that some digital cameras (ones that have RAW shooting mode with more than 8 bit color) allow to squeeze out much more ISO sensitivity than one can set in camera settings. Simply set the camera to its highest ISO setting, set exposure compensation to -1 or -2 steps and shoot in RAW mode, then apply digital exposure compensation by +1 or +2 steps in RAW converter. This allows to utilise extra bits of color representaion recorded by the camera in RAW mode only and simulate 1-2 steps higher ISO speed. This way EOS 300D with hacked firmware squeezes out ISO 12800 (shoot at ISO 3200 and -2 EV correction and then brighten the image in RAW converter). You can even go further and add 1-2 more steps of actual ISO speed in image editing software (after RAW conversion), but then you have to set exposure manually because most cameras can compensate for 2 EV max.
