Transforming perspective while cropping
The Crop tool in Photoshop has an additional option that allows you to transform the perspective in an image. This
is very useful when working with images that contain keystone distortion. Keystone distortion occurs when an object
is photographed from an angle rather than from a straight-on view. For example, if you take a picture of a tall building
from ground level, the edges of the building appear closer to each other at the top than they do at the bottom.

Drag the cropping marquee around an object that was rectangular in the original scene (although it doesn’t appear
rectangular in the image). You’ll use the edges of this object to define the perspective in the image. The marquee
doesn’t have to be precise—you’ll adjust it later.
