Cross polarising effect is where you use a pair of polarising filters - one on the camera and one on the light source (behind the subject) to show stress in plastic which appears as wonderful multicoloured pattern.
You need a polarising filter either attached to or positioned in front of your camera lens. Most LCD screens, like computer monitors, produce polarised light.
You can either change your screen saver to a neutral colour or create a mid grey image and display it (I used Photoshop and just filled the screen). Then take anything that’s made of clear plastic such as plastic cutlery, plastic glasses, cassette and cd cases or geometry sets and hold it in front of the computer screen. View through the camera viewfinder or liveview and rotate the polarising filter until you see the background go jet black. Take your picture
