Stress-O-Vision
I shot a few hours in bright sunlight. Unfortunately, I had to keep my polarized sunglasses off during those hours because they made the lcd screen on my camera go black. The sun exposure temporarily damaged my eyes, so I quickly purchased a pair of unpolarized sunglasses. I eventually noticed that the new pair had tremendous stresses in it, so I took a picture of it.
Capturing an image of the stresses is relatively easy. I back illuminated the glasses with an lcd screen, a cheap polarized light source, and then I took a picture of it with a polarizer on my camera. The background would have been extremely bright white had I not used the polarizer.
