Photographer Captures Incredible Images of Hummingbird's Wings Turn Into Rainbows (8 Pics)

While studying these hard-to-photograph birds, Spencer noticed that the wings would create a prism-like effect when sunlight passed through them, causing rainbow colors to appear. He then began working to snap photos of hummingbirds passing between his lens and the Sun in order to capture these rainbows on camera. Image credits: VITRAL © Christian Spencer
