Braking Light , the illumination of objects from a light source at an angled angle or almost parallel to the surface, provides information about the surface topography and removes the artifacts that are lit. It is widely used in the inspection of artwork.
[Exploration Check]
By using a rake light, the impasto effect and surface texture of a painting is emphasized by increasing surface illumination that faces the light source and exaggerates the shadow on a surface facing away from the light source. In some cases, raking light can help reveal pentimenti (a change in the intentions of an artist). In the case of wall paintings, light rake helps indicate the preparation techniques such as incisions on the support plaster.

Preservation
The conservator checks the object under the light rake during visual inspection and for recording conditions. In the examination of the horses' paintings, the light rake can help document the craquelure, cupping paint, uneven tension on the canvas, or curved on the panel. In examination of wall paintings, light rays can help document the phenomenon of surface damage such as crystallization and micro-delamination, and can be used to monitor the effects of conservation interventions.
