My father worked at Mackintosh’s in Halifax. Every so often, he would bring a bag of what were known as “Throw-Outs” home; misshapen chocolates which were sold off cheap to the factory workers. Whilst this meant a plentiful supply of chocolates for me as a child, you soon got fed up of orange creams and strawberry delights. What I never got fed up of, however, were the colourful cellophane wrappers that encased each of the famous Quality Street selection. You could hold these up to the world and transform the view: skies could become purple and grass blue. You could even hold them up in front of your black and white television and imagine what colour TV might be like if it ever was invented. And for me, these cellophane filters provided an introduction to the wonders of Photoshop.
