1. An industrial viewing station for inspection of defects in a vehicle surface to be examined;
- said industrial viewing station comprising;
a) a visual surround defining an interior sized to receive at least a portion of the vehicle;
i) said visual surround covering the interior in order to selectively control entry of outside light into the interior and to selectively control internal luminance;
b) a lighting arrangement having;
a first selected lighting condition and a second selected lighting condition;
i) said first selected lighting condition comprising at least one(A) point source lighting;
(B) linear source lighting; and
(C) area source lighting selectively orientable to provide generally uniform illuminance of an area in which the vehicle is positioned for examination;
ii) said second selected lighting condition comprising at least one of;
(A) point source lighting;
(B) linear source lighting; and
(C) area source lighting selectively orientable to provide generally uniform illuminance of an area in which the vehicle is positioned for examination; and
c) a control system for selectively activating said first selected lighting condition and said second selected lighting condition.

Abstract
A method of establishing a lighting system and viewing environment for conduct of visual task is provided. The method generally includes steps of providing a visual performance lab, conducting a visual performance study, and constructing an industrial viewing station based upon the results of the visual performance study. The invention also concerns provision of a preferred visual performance lab and development of preferred industrial viewing stations.
