bottom). LUT1 displays the grey values of the grabbed image, except for two grey values: grey

value 0 (underexposed pixels) is shown in green and grey value 255 (overexposed pixels) in red.

LUT2 displays the recorded image in shades of orange. All images are saturated: image A is

underexposed; image B is over exposed; image C is both underexposed and overexposed. The

relationship between the intensity of light emitted from the slide and grey values on the image is

shown in the right column. See text for details.
