The first thing that strikes you when trying to do an evaluation like this is how fraught it is with your own preconceptions. I have no way of measuring the sensor's temperature directly as the cameras environment does not reflect the camera sensor temperature as the camera's own electronics heat up the camera internally. I first found out that the 5DH would not! do a 60 minute exposure at 1600 ISO!

Where to go from here? Here is a 4min exposure at 1600ISO and processed with ImagesPlus for conversion to Tiff and subsequent digital development at a standard level for all subsequent images. This will give you some idea of signal as opposed to noise.
