ShiftN
ShiftN is an intelligent tool capable of analyzing photos and fixing the line distortion (line convergence) effect automatically or with minimal user’s input. Batch processing. The software analyzes the source image, detects vertical lines and performs the correction, making lines run parallel to each other. Apart from the automatic mode, ShiftN gives the user plenty of opportunities to contribute to the image correction process by fine-tuning its parameters. A number of parameters can be adjusted manually to reach the optimal effect: minimum line length, minimum line contrast, maximum tangential deviation, amount of correction, radial distortion and others. Corrected images can be automatically trimmed to eliminate white areas resulting from perspective correction or the user can manually crop the image to preserve the important parts of the photo that are getting cut out in the automatic mode. Any changes to the photo can be instantly undone by pressing a corresponding button on the program’s toolbar, so you don’t have to worry about making a wrong move. Supporting command line processing and three output file formats (JPG, BMP and TIFF), ShiftN can become an extremely valuable asset for photographers making lots of architectural shots that need bulk corrections. ShiftN is a totally free, intuitive and easy to use tool that will efficiently fix visual distortions on your photos and will make you look at them from a new perspective!
