The PNE (Pacific National Exhibition) is a yearly carnival held in Vancouver. In 1983 there was a photographic contest with a prize of a trip for two to Mexico City, complete with a week’s accomodation in a five star hotel. The theme of the contest was “Fun at the fair”.
At the time I was experimenting with slow shutter speeds with flash. The slow shutterspeed gives a sense of movement whilst the flash freezes motion.
