David Hockney experiments with photographic collages and Polaroid composites that utilized grids. While Hockney is most famous for his paintings and drawings, his photographs are also very organized compositions depicting a cubist approach to perception. www.hockneypictures.com

Jo Ann Callis also groups photographs in a grid-like fashion and forces viewers to notice similarities in a series. She creates evocative relationships between ordinary objects, through her multiple image approach. http://joanncallis.com/grids/
