You may have seen these eggs dotting the countryside in autumn. They may look like they were made by some incredibly large bird, but they were in fact made by tractors and contain grass. That is why we in Norway call them "Tractor eggs". I havn't a clue as to what they are called in English.
They are a popular subject among photographers as they lend themselves to a lot of creativity. One can play around with the colours around them,
or move closer in and convert it all to monochrome.
Have a nice Week-end!
