The photo above showing a high arching, dawn rainbow was taken from Alkmaar in the Netherlands, on June 26, 2007. Though this fascinating bow was just briefly visible, it produced a lasting impression. Rainbows have both infrared and ultraviolet components. The infrared component has been captured in this image. The supernumerary bows on the inside of the primary bow weren't visible with the naked eye but show up here. Note that trees appear white, especially on the inside of the primary bow, because chlorophyll is very reflective in the near infrared wavelengths. A faint secondary bow can also be seen.

Photo details: Taken at 6:00 a.m. with a modified Sony W12 using an IR pass filter.
