+(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
+<br/><br/>
+(c) Image of the highlight specular reflection which is caught by placing both polarizers vertically
+<br/><br/>
+(d) Subtraction of c from b, which yields the specular component

+Images are scaled to seem to be the same luminosity.
