Moody Loch Earn at sunset. There are a lot of ducks living nearby which, habituated to humans feeding them, would congregate in front of us, looking to be fed. Although I have no objections to ducks in general, these feathered photo-bombers were a bit of a pest. Solution - one of our number headed off way out of shot with an old bagel and the ducks followed, rats of Hamlyn-like. Another piece of essential photography equipment to not be without - duck food!
