How do you keep a small boy occupied on a rainy day when his mother is working her way through a cornucopia of leather handbags? One father found the answer in a large multi-coloured umbrella which his son was swinging happily in all directions, mercifully without hitting anyone. I suppose the bright colours gave fair warning to any potential victims.
They also made for a great photograph, but then won’t that all be lost when you process it in mono? To some degree yes, but it made the boy a more important feature which as it happens is no bad thing.
