PTGui for Mac combines similar images in order to create a new one that is of higher resolution. The software comes with a free trial and attempts to guide you through the process by breaking it down into three more or less easy steps. Even though the end result will vary wildly depending on the quality of the images used, the app allows for a high degree of manual fine-tuning, which helps with the removal of faults.
When launched, PTGui for Mac offers you video tutorials on how to get started with the app and how to take photos suitable for the software. After loading the images and analyzing their EXIF data, the application will attempt to find overlaps called "control points" and generate a single image. We were able to fine-tune those points and add new ones, although the app generally manages to align the images on its own. Other noteworthy actions include moving and rotating the image by a numerical value, blending images in various ways, and setting different projections such as a 360° panorama. When you're happy with the alignment, the app lets you choose one of five output formats as well as a resolution before generating the final image. The overall quality is lower than that of a panorama taken with a good-quality smartphone.
If you shoot with a camera that doesn't support a panorama mode, or have old images you'd like to stitch together, you should try PTGui for Mac. Although a camera's native panorama mode will yield generally better results, this app can still bring value by not restricting the panorama's shape.
Editors' note: This is a review of the trial version of PTGui for Mac 9.1.9.
Use PTGui to stitch any number of photos into a panoramic image. Some benefits of PTGui, when compared to other stitching software: PTGui can stitch multiple rows of images. Create 360 degree cylindrical panoramas, 'flat' partial panoramas and even spherical 360x180 degree panoramas. No need to keep the camera level: PTGui can stitch rotated and tilted images. Virtually unlimited output size: create Gigapixel panoramas from hundreds of images! Layered output allows full control over the final stitched result. PTGui stitches most panoramas fully automatically, but at the same time provides full manual control over every single parameter. This enables stitching of 'difficult' scenes, where other programs fail. Full 16 bit workflow for best image quality.
