Departing Storm over Bembridge Lifeboat Station by Jamie Russell
Photo location: Bembridge, Isle of Wight, UK
Camera: Nikon d7500, Sigma 10-20 lens.
After chasing storms and showers west to east across the Isle of Wight to capture some incredible rainbows, Jamie reached Bembridge as the final shower left. "In a panic (he) waded into the waist-deep water, fully dressed, just to compose this scene".
Rainbows are optical phenomena that occur when sunlight shines through raindrops. The light is refracted as it enters the raindrop, then reflected off the back of the droplet and then refracted again as it exits and travels towards our eyes. This causes the sunlight to split into different colours. The sun needs to be behind the viewer and needs to be low in the sky. The lower the sun in the sky, the more of an arc of a rainbow the viewer will see. Also, the rain, fog, or other source of water droplets, must be in front of the viewer. The angle at which the light is scattered is different for everyone, which means that every rainbow is unique to the observer.
Double rainbows form when sunlight is reflected twice within a raindrop. They are relatively common, especially when the sun is low in the sky, such as in the early morning and late afternoon. The second rainbow is fainter, and more 'pastel' in tone and a key feature of a double rainbow is that the colour sequence in the second rainbow is reversed.
