Contrast setting is totally interactive with the brightness setting, they function together to deliver the dynamic range
or contrast ratio that the display can do. In the typical showroom floor setup you will find displays set to dynamic modes,
contrast is typically clipped in this mode, the intension is to be brighter than the neighbouring tv so to stand out and get
your attention. This is a legacy of older technologies which had limited contrast ability, however even in modern displays
setting too high will clip and crush any visual information.
In the example contrast has been turned up to an excessive degree, initially, this appears to create additional "punch" in
the image, but extended viewing of the picture becomes quickly fatiguing, and possibly even damaging to the display device itself.
Note the complete loss of detail in Benjamin's cheeks and nose as the highlight details are crushed. Of equal importance note
the clipped greyscale in the background.
