Abstract
The human eye functions in the brightness range 10-6to 104 foot lamberts, equivalent to between starlight and intense sunlight. The quantum efficiency of the eye is only 1%, so at very low light levels only very contrasty objects can be detected, such as stars. Intensified cameras function in a narrower range of scene brightnesses centred around the low light level limit of the eye.
