I had to keep running inside to change lenses to capture the whole rainbow and finally settled on my Tokina fisheye 10-17mm lens set on 10mm to capture the double rainbow. When I went out onto the boat pontoon I was so surprised to see that the reflection in the water made a full circle rainbow…how cool was that :-)
Images were taken on the 24th May using a Canon 70D camera and assortment of lenses grabbed very quickly from my camera bag using a Canon 10-20mm lens & Tokina fisheye lens.
