Went outside a little before 6:30 am to fill birdfeeders in my backyard and a light rain began to fall. The sun rose soon after and this rainbow appeared. It was too wide for a single photo so I took three and stitched them together. We are in a drought so rain and rainbows have been scarce the last couple of years.

Nikon Coolpix S9500

Image Composite Editor to stitch the three photos into one, then GIMP to brighten and increase color saturation.
