December photograph by David Stephens

Colours brighten a storm-struck city

Rainbows are formed when sunlight is refracted (bent) and reflected while passing through raindrops in the atmosphere. Blue light refracts at a greater angle than red light, resulting in the separation of the colours in the spectrum of white light.

David Stephens and his daughter were on their way home from school when a storm front came through Melbourne around 4 pm on 23 August 2012, bringing heavy rain and hail. They got wet rushing home on foot, but David stepped back outside to look at the sky: he was soon inside looking for his camera. 'I just walked out of the front and photographed the rainbow in brilliant sunshine,' he says.
