ShiftN permits correction of converging lines a majority of the correction work is taken over automatically by the program. Both the effects of converging lines and poor camera angle are corrected automatically. The process in ShiftN is to search the image first for straight lines and edges, and to consider those which are sufficiently vertical to be likely architectural elements. On the basis of these straight line segments the program runs an optimization process that attempts to determine perspective, correcting the image so the lines are made parallel to each other.
