PLASTIC FANTASTIC

PROJECT 1

James Paterson shows you how to create striking and vibrant abstracts

Many of us are now accustomed to using circular polarizing filters on our lenses. They’re useful for enriching colours in landscapes – especially blue skies and foliage – and invaluable for cutting through reflections or atmospheric haze.

But polarizers aren’t just for lenses. Something magical happens if we polarize our light source too. This is called cross polarization, and the technique is simple. We need both the light entering our camera and the light emitting from our source to be polarized light. It’s a classic technique that has many uses, both practical and creative.

Cross polarization can result in photos with zero reflections and glare, which makes the technique useful for practical things such as dental photography, because eliminating the glare allows for clearer pictures of teeth.

But if you want to get creative, it also allows you to capture otherworldly colour spectrums. Captured under cross-polarized conditions, any hard, clear plastic objects like the plastic champagne flutes here are transformed into vivid, rainbow displays of colour. You probably have everything you need to get started at home. As well as a polarizing filter for your lens, you’ll also need a polarized light source.
