Guy was born and raised in England, where he studied Theatre and Photography before receiving a BA from Royal Holloway, University of London with a focus in Screenwriting and Directing Screen Fiction.
He moved to Los Angeles to study Cinematography at the American Film Institute Conservatory, where he earned an MFA in the discipline.
His graduate thesis film Dirty Laundry went on to earn Guy the 2014 Linwood Dunn Student Heritage Award from The American Society of Cinematographers.
Guy now works between the USA and the UK. He strives to keep his work free from an identifiable style, believing that the work of the Cinematographer should solely serve the narrative. His goal is to construct cinematic imagery that concisely conveys the emotion of each film, whilst always clearly telling the story.
