Repetition is a key aid to learning because it helps transition what we observe from the conscious to the subconscious part of our memory. It is commonly used in advertising as a way to keep a product in the forefront of a consumer's mind. But repetition can also lead to fatigue, whereby consumers become so tired of an image that they simply tune it out.
As far as photography goes, repetition seems to add an uneasy sense to a series of images--it's almost as if these were grouped by mistake. Often a viewer will examine a series of repeating images to search for differences across them. Sometimes the slight differences between photos add a film-like quality to the series, and allow the viewer to construct their own narrative from the repeating images.
Particularly in the digital age, photographers generally take many shots of the same scene, but then select their best "capture" to display. But this habit may well undermine the possibility of using repetition to connect with a viewer on a sub-conscious level. In this series, "repetitions" of various kinds are presented--some of these are almost exact copies, while others include images that are similar to one another in just slightly different ways.
