Inspired by the incredible work of digital colourist Marina Amaral (get your hands on her book The Colour of Time if you haven’t already), I’ve been learning how to colourise black and white photographs, with some pleasing results that have found their way into other aspects of my work. For example, once I’d brought this Leigh Wiener portrait of Grace Kelly to chromatic life, I had to go one step further and turn it into a poster for 1956 film The Swan.
