I use two polarising filters for an SLR camera 4 cm in diameter. But small squares of polarising filters can be obtained quite cheaply. At a pinch the two sides of a pair of plastic clip-on Polaroid sunglasses for prescription spectacles can be bought for a few dollars. You can just view the objects or record the image with a camera with close-up or macro facilities. In my case I use an old colour security video camera with an SLR lens and extension tubes attached and send the video still to a PC capture card.
Image editing software can make captured digital images more dramatic.
Distracting backgrounds can be painted out and changing the tonal balance can give the colours more 'punch'. Some suggestions on what to view The plastic gauze from a first aid dressing Most first aid dressings like Elastoplast have a plastic gauze over the internal pad to hold it off the wound. Many clear plastic objects around the home may give colour effects. The stresses in the plastic around lettering, embossing etc. The image right shows the makers mark on a music tape cassette box.
