depends on the chosen colour. Let's say that we have chosen the red light
source; once the filter is applied, a full image will acquire a red hue;
• Intensity – specify the source intensity and the strength of its colour. The
higher the value of the parameter, the more intense the light source is. If
the image needs marginal illumination only, the value must be reduced;
• Position – determine the coordinates of the light source;
• Direction – set the direction of the light source;
Note!
The latter two parameters are not always active because they depend on the type of
light source. For instance, if the Point type is chosen, it is not possible to set the
direction of the light source as it illuminates the entire image.
