Correct linear distortions of a perspective and adjust the angle of the horizon
Edit By BS Editor: Perspective distortions often appear in the architectural building photography and urban landscape photography. Such distortions arise from taking an urban landscape using a wide-angle lens and also may be caused by inappropriate Aspect angle.

Perspective Pilot is specially designed software for perspective correction of a photo.
The program automatically crops the external edges arising after photo correction. you can free download Perspective Pilot 2.1.1 now.
