Well, not our fields, but the surrounding ones. Just by chance I happened to look up and out of the window this evening and saw the endpoint of a rainbow close to our house. Walking out the backdoor lead me to this sight.
This panorama was stitched together from three shots in Hugin. The shots were taken at f/8, 1/800 s, 18 mm, ISO 400. Some post processing was also done first in Lightroom and then in Gimp (final crops and resize).
There is also a larger version of the shot available.
