PTGui is panoramic image stitching software for Windows and Mac OS X. It comes in a free trial version and two paid versions Standard and Pro.
The software originally started as a Graphical User Interface for Panorama Tools which is where the name “PTGui” comes from. It has now evolved into a full featured, industry leading photo stitching application.
The application is downloaded onto your computer and thanks to OpenCL GPU acceleration PTGui is able to stitch a 1 Gigapixel panorama in about 25 seconds on modest hardware.
PTGui stitches and allows you to create fully spherical 360° x 180° panoramas for drone photography.
PTGui includes interactive panorama viewers both for local viewing on your computer, and for embedding in a web page.
PTGui has a really good trial version which is fully functional, with no time limit or close out pressure, but stitched panoramas have a visible PTGui watermark.
The PTGui Pro version offers full support for HDR (High Dynamic Range) 360 panoramas.
Standard Personal License is £72 +vat = £87
Pro Personal License is £136 +vat = £163
Standard Company License for 3 seats is £164 +vat = £197
Pro Company License for 3 seats is £318 +vat = £381
Regardless of the type, each license includes free updates for one year after purchase. A license does not expire: you can continue using the version of PTGui or PTGui Pro for which your license is valid.
What is the Difference between the Standard and Pro Versions
Here is a list and brief explanation of the additional features in the Pro Version
There are three extra features relating to batch processing of images in the Pro version. These are
- Batch Stitcher can generate control points and set up a panorama
- Batch Builder: scan folders for panoramic source images and automatically create projects based on a template
- Support for Batch Lists (save and load a list of jobs for the Batch Stitcher)
The Pro version will Stitch and blend HDR (high dynamic range) and LDR (low dynamic range) source images into an HDR panorama.
The pro version includes a built in tone mapper for all of the images and blend parameter for blending the nadir image in a spherical panorama.
Viewpoint correction allows one to use different camera viewpoints in the same panorama, provided that the relevant part of the images is approximately flat. It is particularly useful when including a handheld nadir image in a panorama taken from a tripod.
Vignetting correction minimises any color and brightness differences between the source images. Automatic color and exposure adjustment, corrects vignetting, flare, exposure differences and white balance differences.
The correction is fully automatic; by analyzing the contents of overlapping images, PTGui Pro can determine the vignetting characteristics of the lens and compensate for it.
Masking is the most powerful single extra feature of the Pro version. When creating a panorama from multiple photos, moving objects can cause stitching problems. For example a person walking around the scene may appear in the panorama twice, or may even be cut in half by the seam between two overlapping images.
PTGui Pro masking tool can be used to prevent these problems. By masking you can tell the blender precisely which part of the images should or should not be visible in the blended panorama.
We recommend the PTGui Pro version because of the Masking feature alone
