Abstract
Improved visual effects which are quite pleasing are obtained by illuminating paintings with a lighting system comprising at least two light sources directed on the art work from in front and above, and in front and to the side, respectively, with at least one of the light sources varied in intensity from a maximum to a minimum, the other light source maintaining at least a minimum amount of illumination when the one light source reaches it minimum.
Claims16
A system for creating and displaying art work comprising:
- (a) a first light source;
- (b) means to support said first light source at a position above and in front of the art work;
- (c) a second light source;
- (d) means to support said second light source to the side and in front of said art work;
- (e) means to fix the intensity of said second light source;
- (f) means to stepwise vary the intensity of said first light source while creating the art work, in said stepwise manner, furthermore means to display said art work with said displaying means comprising:
- (g) means to adjust the intensity of one of said light sources;
- (h) means to set a maximum intensity for said other light source and to automatically vary said other light source between said maximum and a minimum, which at least approaches zero intensity, at a predetermined rate;
- and wherein:
- (i) said art work is responsive to adjustments in the intensity of said light sources such that varying the level of light incident of said art work give the appearance of a changing scene.

The method of lighting art comprising:
- (a) directing light from one light source onto said art from in front and above;
- (b) directing light from another light source onto said art from the side and in front of said art work;
- (c) setting the intensity of at least one said sources to a predetermined minimum lighting level;
- and
- (d) varying the intensity of the other of said sources at a predetermined rate between a predetermined maximum and predetermined minimum level which approaches zero;
- and wherein:
- (e) said art comprises a painting and further including creating said painting by steps comprising adjusting said first light source so that it remains fixed at various ones of the levels between maximum and minimum and, at each of said levels creating said painting to give different desired effects, whereby as said light is varied on the finished painting, different effects will be evident.
