Executed in a manner that is playful, yet driven with tension, Tilley's photography exacts an anticipation of the moment that is about to happen. Momentum is a collection of some of Tilley's best work to date. His photography continuously captivates the viewer, leading us to something perhaps unexpected, out of context or that may cause us some unease but in a fun and highly-dramatic way. The aesthetic is bold and well-designed with each image portraying a story at a paused point in time allowing the narrative of the image to be interpreted by the viewer. With this, the viewer should enjoy the surreal element to the work and embrace this style presented throughout the book.
