Today's project is another version of cross polarisation I've been doing a bit of lately. In this example I turned my LCD computer screen on its back facing upwards. This became the base for a collection of cheap disposable shot glasses (£1 for 40 from Poundland). I arranged them in a pattern, edged up side by side to create a grid, and then positioned the camera above with a polarising filter attached to the lens.
I adjusted the zoom to ensure a tight crop and took this photo. Exposure was automatic.
