Screen dumps of various experimental results

Using a different range of polariser angles:

Changing light source direction

Filter in front of source:

Rotating the camera

Different lens

Changing camera and moving ball in field of view:

Replacing snooker ball with rough ball:

Two light sources

Specular balls

Glass ball

Effect of polarising the source

Adding filters to source

Source in different parts of field of view

Fingerprints

More light source positions for multiple sources

Camera at different exposures and angles (top to bottom: camera rotated to 0, 45 and 90. Left to

right: increasing exposure)
