I just read through the other post about rainbows and thought I would post a couple of my own. I saw this double rainbow this spring, just after I purchased my first DSLR (Nikon D5000). I took these pictures from my roof top.
When I took the pictures I had no idea about how to create a panoramic shot, or stitch photos together. The fact that I can't seem to stitch the top of this rainbow on to the panorama is a great frustration. I really wish I could have the moment back now that I know a little more. It was a spectacular scene.
Atleast it has motivated me to learn faster. Hopefully I will get another chance like this someday.
