Shift Lens App 2.5 has been developed to do perspective correction on images. There are many reasons and explanations why lenses deform perspective. To solve this problem, photographers use special Tilt-Shift lenses for SLR cameras to correct the trapezoidal effect. Tilt-shift lenses are heavy and bulky and a tripod is recommended. Besides, this photographic equipment requires setup, positioning, leveling, etc...
The purpose of Shift Lens App 2.5 is to enable the use of any available photographic equipment. This means that the photographer does not think about lens type, tripod, leveling, and viewing angle. The only thing is to take pictures and the rest will do Shift Lens App 2.5.
Shift Lens App 2.5 can do all perspective corrections in both vertical and horizontal planes no matter the perspective deformation degree. Also, it can perform angle straightening by defining the angle on the image.
