Summary
Image: Separating specular and diffuse reflected light
(a) Normal image in dot lighting
(b) Image of the diffuse reflection which is caught by placing a vertical polarizer in front of the light source and a horizontal in the front the camera
(c) Image of the highlight specular reflection which is caught by placing both polarizers vertically
(d) Subtraction of c from b, which yields the specular component
Images are scaled to seem to be the same luminosity.
