Sometimes the eye is constantly moving between two competing elements within the frame in order to determine the spatial relationship between them. Without a doubt, one of the most frustrating aspects of photography is the inability of a photograph to break free from its own inherent flatness – its two-dimensionality. Photographers often talk about light in terms of the physical properties they reveal and their effect on a subject’s appearance. Many successful photographers make use of sophisticated sense of perspective and space by skilfully placing a series of elements or points of interest at varying distances throughout the frame: foreground, middle and far distance. Perhaps more than any other technique, photographers should be aware of the principles behind depth of field. Layers created by reflections allow photographers to project more than one meaning or interpretation to their image while at the same time inviting the viewer to perhaps switch between messages.
