Very good program,for professional photographer
Converging lines in photographs, particularly of buildings, forests and
so on, can often detract from the desired effect.Architectural elements
in photographs often have diagonal lines, but the mind thinks of
buildings as having vertical and horizontal lines. Converging lines are
caused by the film-plane being angled relative to the object of the
photo, and that effect can be avoided optically by the use of either a
shift lens (quite expensive) or the use of a medium or large-format
view camera having swing features. With a shift lens, the lens itself
is shifted perpendicularly to the z-axis, so that the film level can
remain parallel to the subject. Shift lenses are mechanically and
optically more complex than standard lenses, which is why they are
comparatively expensive. Often, one is shooting with a "point and
shoot" camera, where the option of changing lenses does not exist. The
advent of digital photography or scanning existing photos from prints
opens up new possibilities for manipulating the picture. Here is where
ShiftN shows its strength.
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.
ShiftN permits
correction of converging lines; a majority of the correction work is
taken over automatically by the program. Using the "automatic
correction" item in the menu is in most cases sufficient to produce a
satisfying result. Both the effects of converging lines and poor camera
angle are corrected automatically.
