The PTGui application was designed to be panoramic stitching software for Windows and Mac OSX. Originally developed as a Graphical User Interface for Panorama Tools (hence the name), PTGui now is a full featured photo stitching application.
PTGui comes in two versions: PTGui and PTGui Pro. The main difference between the two versions is support for HDR stitching, viewpoint correction and vignetting, exposure and white balance correction in PTGui Pro.

· Stitched panoramas will have a visible watermark
· Saves only the first 2 images of panorama
· The Panorama Tools stitcher and optimizer are not supported (only the built-in PTGui stitcher and optimizer)
· The trial version expires. Updates will be downloadable from this website
· Nag screen
