Summary[edit source]
Image 1 rearranged to 2 rows: Separating specular and diffuse reflected light
(a) Normal image in dot lighting
(b) Image of the w:diffuse reflection which is caught by placing a vertical w:polarizer in front of the light source and a horizontal in the front the camera
(c) Image of the highlight w:specular reflection which is caught by placing both polarizers vertically
(d) The difference of c and b yields the specular highlight component
Images are scaled to seem to be the same w:luminosity.
