Hay Hill Gallery in Cork Street, London, is showing Jeffrey Robb Liminal State until 13 July. This exhibition of work by Jeffrey over the last 5 years includes moving 3D images using lenticular photography, a process of capturing multiple images of a subject. Jeffrey combines these images into a single 3D image on a computer. Red, green and blue lasers expose the photographic substrate, which he combines with a vertically aligned optical lens to produce the finished fine art image. Every stage of the process is done by hand and requires great skill. The gallery website shows an animated GIF to give you a rough approximation of the 3D movement this technique creates: CLICK.
