Using Vanishing Point
Va n ish i ng Poi nt is a spec ia l plug - i n t ha t a l lows
for perspective cloning. Essentially, a user can
identify perspective planes (such as sides of a
building), and then apply edits such as painting,
cloning, copying or pasting, and transforming.
All the edits to the image honor the perspective
of the plane you are working on; basically, you
are retouching the image dimensionally. This
produces significantly more realistic results, but
it does take some time to set up.

Vanishing Point
1. Close any open files, and then open the file
Ch11_VP.tif from the Chapter 11 folder. This
photo of a sign is marred because one of the
letters is burned out. With Vanishing Point
you can clone or repair the sign.
2. Invoke the Vanishing Point dialog box by
choosing Filter > Vanishing Point. This will
bring up a custom interface for defining the
perspective planes, as well as tools for editing
the image.
You mu s t i r s t s p e c i f y pl a ne s t o de i ne p e r -
spective in the image. For this photo, you
want to replace the burned-out letter O.
3. Choose the Create Plane tool and define the
four corner nodes of the plane surface. You
can use the edges of the sign for guidance
when creating the plane. See the figure for
4. After creating the four corner nodes, Photo-
shop allows you to move, scale, or reshape
the plane. An accurate plane means accurate
vanishing point effects, so take your time. If
there's a problem with a corner node's place-
ment, the bounding box and grid turn red or
yellow. You must then move a corner node
until the bounding box and grid turn blue or
green. This means that the plane is valid. A
plane that is yellow or red is a problem plane
and needs to be adjusted.
