Sometimes one doesn’t have the option of using a tripod, selecting the exact point of view, or even choosing the right exposure. This was taken through a train window as it travelled across Rannoch Moor one evening.
The dirt on the train window somehow didn’t get in the way. I used my compact camera on programme mode; every possible scene was past in a flash, time only to press the shutter and hope. Most of the others were failures but this photograph worked.
Moral: take the picture whatever the problems.
