Impaired Vision Setup

Computer screen set up with a clear white page using MS Notepad to give the background for a photoelasticity shot.

The clear plastic shot glasses are raised up on a clear plastic box and you can see here the effect from using the polarising filter against the white background. To turn the background black, the filter is rotated until it appears black.

It really is that simple :)
