Adaptive Wide-Angle Correction
A common flaw caused by wide-angle lens is distortion. If you
shoot with a very large field of view (wide-angle rectilinear or
full-frame fisheye), the photo will often show a bending of straight
lines and other distortion near the edges of the photo. The Adap-
tive Wide Angle Correction plug-in (new to CS6) can fix percep-
tible distortion. The plug-in requires only a small amount of input
from a user to know which lines should be straight.
Let's try using the command on a very distorted image.
1.
Close any open files, and then open the
Ch11_Adaptive_Wide_Angle.tif file from
the Chapter 11 folder.
2.
Choose Filter > Convert for Smart Filters to
ensure flexibility in editing.
3.
Choose Filter > Wide-Angle Correction.
4.
Choose a correction method from the pop-
up menu. You can choose among Fisheye,
Perspective, Full Spherical, or Auto.
Try out the different methods to see their dif-
ferent approaches. For this project, Auto works well.
