(astronomy) the amount of angular degree of the apparent
change in the
position of an
object resulting from the
change in the direction or
position from which it is viewed. The parallax of an
object may be used in determining its distance from the
observer because smaller angles indicate greater distance.
(photography) the apparent displacement of an
object that
results from the
change of perspective with which it is viewed. In photography, the
term directly applies to the
different perspectives of an
object through the viewfinder and camera lens because of their slight distance apart. Such a parallax
error can result in a poorly composed
image or in part of the desired
field of vision being omitted from the
frame.
