This week I have been experimenting with UV light and its fluorescence, also, I am trying to determine what settings in the camera would create a better image. I started using a DSLR camera because my phone camera does not have controls of shutter speed and aperture. I am using different angles of light to decide what work best.
Raking Light vs Direct Light
Raking light
“Raking light is a technique in which a painting is illuminated from one side only, at an oblique angle in relation to its surface.
Raking light helps to reveal the surface texture of a painting
Raking light is used to reveal a painting’s surface texture. Raised paint surfaces facing the light are illuminated, while those facing away create shadows.
The increased appearance of paint texture can easily be seen, photographed or recorded digitally. Conservators use raking light to judge aspects of the condition of a painting”.
