Rephotography — sometimes called repeat photography — is the practice of photographing the same location from the same position on two or more separate occasions, with a significant time gap between images. The objective is a direct visual comparison: a diachronicConcerned with the way something changes or develops over time, as opposed to examining it at a single fixed point. In rephotography, a diachronic image pair shows the same location across two or more points in time, making change — or continuity — directly visible. The term contrasts with synchronic, which describes a snapshot of something as it exists at one particular moment. More pair that shows what has changed, what has survived, and what has been lost entirely. Read the Post – The Art and Craft of Photographing Time. Rephotography Organisations and Information
