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.
To make photo correction:
1. Press and move the cursor to set a line, which should be either vertical or horizontal. 2. Set another vertical or horizontal axle if needed. 3. Press the Finish button to reduce the noise arising from perspective correction.
