Create rainbow cross-polarisation effects using your iPad
This is a technique that looks impressive but which is very easy to do with a tablet.
Unlike other light sources, such as a lightbox, a computer screen is already polarised, so all you need is a polarising filter fitted to your camera and the two will interact to cross-polarise the final image.
Place a clear plastic object on your tablet’s screen and position your camera directly overhead using a tripod, then rotate the filter and see what futuristic effects you can create.
We used a set of rulers, but something as simple as clear plastic cutlery can look equally striking.
