A Photomosaic marries the art of photography with the science of powerful image computing to produce original expressive works of art that are not only unique but also beautiful. Appealing especially to lovers of imagery and optical illusion, when held at arm's length Photomosaics arrange themselves into a composition revealing a recognizable and often well-known image. When held close up, they explode in a riot of colour and exquisite detail rendered in gorgeous and telling imagery. This third fascinating collection of Robert Silver's work focuses on portraits of significant historical and contemporary figures from a wide variety of fields. Rich with humour and meaning Photomosaic Portraits will have special appeal to all those interested in optical illusion and imagery.
