Rainbow over Castle Geyser

Yesterday I posted a photograph of Castle Geyser with a sunburst. This photo of a rainbow over Castle Geyser was taken a few  minutes after the wind shifted and forced us to move around to the other side of the Geyser. Not long after, a rainbow formed and we spent a few minutes photographing this magnificent scene. I was surprised how strong the rainbow came out. Most of the time rainbows are more impressive in person. I think the proximity and the white backdrop helped intesify the colors. Did I mention that Castle Geyser is one of my favorite geysers in the park?

Rainbows form around some geysers caused by the reflection, refraction and dispersion of light in the fine geyser mist which results in a spectrum of light appearing near the geyser. These rainbows tend to shift quite a bit as the wind blows the mist in different directions. Just a minute later the rainbow was a full-length rainbow to the left of the geyser. What a bonus.

This image was taken with my Canon EOS 5D Mark IV using my Canon EF 16-35mm f/4 Lens set on 24 mm. The camera was set on Manual mode with the aperture set at f/11, shutter speed at 1/100th of a second and the ISO set at 100. I used a polarizer filter to enhance the sky and I used a tripod for stability. This is a single image processed using Lightroom and completed in Photoshop using Nik Color Efex Pro.

  1. Seeing this and the rest of your photos provides proof that Yellowstone in winter is worth the trip (and cold weather…). Great shot!
