It all began innocently enough. On January 1, 2016, Yorkshire Post photographer Tony Johnson was experimenting with a new camera. The result was a black and white portrait of his son, carrying the skateboard he had got for Christmas. Another time, it might have become just another family photograph to go with the hundreds of others Tony had taken. Instead, it was the start of a year-long project which is about to be published in a coffee table photographic book called 366 (2016 being a leap year).
