Whittle’s practice encompasses photography, painting, drawing, publishing, writing and organising often bringing these mediums together. His work attempts to navigate the duality of definition, ambiguity of usefulness and diluted purpose of the quiet and unassuming two-dimensional image. The work investigates time within production as well as time suggested by materials and methods.

Whittle has curated exhibitions (Greetings, Mauve, Vienna 2019, These fingers read sideways, MONOMATIC, Edinburgh 2018 and RIFF at Baltic Project Space, Newcastle 2014) and the ongoing project Slide Night. In 2016 he founded Long Distance Press, a small publishing company, with artist Adam Shield- to date they have published 14 books. In 2017, Whittle took part in Syallbus II, an altenative peer-led learning programme organised by Wysing Arts Centre and hosted by East Side Projects, S1 Sheffield, Studio Voltaire, New Contemporaries and Spike Island. 

Whittle has contributed to University programmes through Visiting Lecture positions at Newcastle University, Middlesbrough Univeristy, Sunderland Unversity, Goldsmiths University of London and Edinburgh College. He has also devised and delivered learning programmes at Tate Modern, The Fruitmarket Gallery, Edinburgh Sculpture Workshop and is currently a Tutor at Stills Centre for Photography, Edinburgh. 

Recent publications include Conche Paintings and IonRU published by Long Distance Press, the self-published Your Space is Only a Line, My Mate Bill Blake and Camper Vans Deuce, Right On published by Foundation Press and Tessex? published by Image Text Ithaca Press. He is founder of the curatorial project MONOMATIC, a roaming project space. He has shown in Manchester, London, Worcester, Newcastle, Liverpool, Toronto, Munich, Dortmund, Vienna, Brussels, Los Angeles and Istanbul.
