Characters are the stuff of street photography, so when I saw this bright orange hat appearing along the north bank of the Thames I just had to ask for a picture. Beneath the Vivienne Westwood hat, immaculately attired in retro Saville Row finery, I found The Man With the Hat, John Aspey, a well known character around West London. John is also known as William Charteris, author of Shakespeare in Space, a “science fantasy for children with grownups in mind”. He’s also a keen photographer, a regular customer of my local camera shop.
