Parallax

Parallax error
When the motif seen through the camera’s viewfinder does not correspond with what will be captured by the lens due to the different viewing positions of the two. When shooting close up, the degree of error can lead to incorrectly framed images. Some cameras feature a viewfinder with correction markings to prevent this while others automatically compensate for the parallax effect. In digital cameras, the parallax error can be avoided by framing shots with the LCD monitor (if available).
