Definition
Rephotography is the act of repeat photography of the same site, with a time lag between the two images; a "then and now" view of a particular area. Some are casual, usually taken from the same view point but without regard to season, lens coverage or framing. Some are very precise and involve a careful study of the original image.

Consideration to Choose The Scene
The accurate rephotographer needs to determine several facts before taking a new image: Continuity Building (Object) Other Object ‘Link’ of two image Point of View (See next slide) Time: Season, Hour (See next slide)

Point of View
The vantage point from which the original photographer took the view may have disappeared over the years, so the rephotographer has to choose an original view for which the vantage point is still accessible, or arrange to rent equipment to duplicate the original position of the camera.

Time: Season, Hour
Through scrutiny of the original image, the rephotographer needs to determine the season and the time of day from observation of the vegetation and the shadows shown in the original view. The best way to do this is to set up a camera at the original viewpoint, at approximately the right season and time, and wait with the original view in hand, until the shadows reach the same positions relative to surrounding objects. If done with extreme accuracy it should be possible to place one image over the other, and see the edges of buildings match exactly.

Serious Side
Rephotography has its serious side as well. It is often used by the scientific world to record the effects of erosion over time, or to measure the extent of sand banks in a river, or other time-related phenomena.
