Shift Lens App 2.5

Shift Lens App has been developed to do perspective correction on images. To solve this problem, photographers use special Tilt-Shift lenses for SLR cameras whose role are to correct trapezoidal effect. Tilt-Shift lenses are heavy, bulky and tripod is recommended. Besides, these photographic equipment requires setup, positioning, levelling, etc…

Purpose of Shift Lens App is to enable use of any available photographic equipment. This means that photographer does not think about lens type, tripod, levelling and viewing angle. Only thing is to take pictures and rest to do with Shift Lens App;

Shift Lens App can do all perspective corrections in both vertical and horizontal plane no matter the perspective deformation degree. Also it can perform angle straighten by defining angle on the image.

Shift Lens App is designed for all kinds of photography where perspective corrections are necessary especially on images taken with wide angle, ultra wide angle and “Fisheye” lenses!

Features:

The “Angle Straighten” is for angle corrections on the image. Angle correction can be done by clockwise or by counterclockwise direction. The angle degree depends on line slope of the image.

The “Vertical Straighten” is for vertical perspective corrections. Vertical straighten performs perspective corrections like optic Tilt-Shift Lens. Vertical straighten is perfect tool for barrel deformation correction on images taken with wide and ultra wide lenses.

The “Horizontal Straighten” is for horizontal corrections like pincushion deformation on images - suitable for perspective correction of panoramic pictures. With combination of Vertical and Horizontal straighten (or vice versa), successful correction can be accomplished on images taken with Fish-eye lens.

Advanced Vertical and Advanced Horizontal Straighten are new tools developed to allow users influence on straighten perform. User defines the range where straighten will occur by Border curves. There are 2 another curves called Guide and Leading curves. Guide curve represents deformation line. Leading curve is users way how the Guide curve will be processed.
