Lately we've been having some minor drizzles near sunset which have resulted in some brilliant rainbows. Several times they have appeared as double rainbows, but the doubles have been so faint they didn't show up in my pictures. Today I was able to capture one on film:
One of my sunflowers (with a tiny raindrop) looks on....
This was quite a surprise. Just as I snapped the photo, a streak of lightning began to spider across the sky. I didn't catch it in full glory but you can see the start of it at the top right of the shot and it extends down through the rainbow.
A raindrop on the lens blurs the rainbow.
