Visual Illusions In Motion With Moir Screens

Produce your own moire effects in motion with this unusual and stimulating book. All you need is included: 80 optical art patterns that are intriguing in themselves, plus and acetate screen with four moire overlays. An almost infinite number of effects is possible. Experiment with the overlays and the patterns, and see what effects you can come up with.

By moving the moireacute; screens provided in different ways over these optical designs, artists and illustrators can create an infinite number of fascinating patterns with startling, wavelike effects. Rich source of inspiration and royalty-free material ideal for use in print, film and computer applications. 60 patterns.

Intended for students in the visual arts and for others with an interest in art, but with no prior knowledge of physics, this book presents the science behind what and how we see. The approach emphasises phenomena rather than mathematical theories and the joy of discovery rather than the drudgery of derivations. The text includes numerous problems, and suggestions for simple experiments, and also considers such questions as why the sky is blue, how mirrors and prisms affect the colour of light, how compact disks work, and what visual illusions can tell us about the nature of perception. It goes on to discuss such topics as the optics of the eye and camera, the different sources of light, photography and holography, colour in printing and painting, as well as computer imaging and processing.
