Panoramic photo stitching software; Pro version available.

Overview

PTGui is panoramic photo stitching software. Originally developed as a Graphical User Interface for Panorama Tools (hence the name), PTGui now is a full-featured photo stitching application.

Use PTGui to stitch any number of photos into a panoramic image.

Some benefits of PTGui:
  • 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
  • And much more...

What's new in PTGui

Version 11.19:
Improved:
  • LibRaw (used for decoding of RAW files) has been updated. PTGui can now load Canon .CR3 files and GoPro .GPR files. For details see LibRaw 201910 snapshot.
  • A 'noise floor' slider has been added in the Exposure/HDR tab. This is used when merging bracketed images (in the True HDR workflow). Use it to remove excessive image noise that might appear in HDR panoramas generated from relatively noisy images (e.g. images taken at high ISO). See the tooltip for the Noise Floor slider for more information.
  • Performance improvements when using GPU acceleration (40% faster for certain projects on certain hardware).
Fixed:
  • Bug in PTGui web viewer (used by Publish to Website) on an iPad with iPadOS 13: no response from the touchscreen, so navigating the panorama was not possible. All newly created web pages from Publish to Website will use the new version of the viewer. Existing published panoramas can be updated by replacing PTGuiViewer.js with the new version: download the latest PTGuiViewer.js here.
  • If a set of images with a repeating exposure sequence was loaded, and 'This is not an HDR exposure set. Do not enable HDR mode' was selected, the control point generator could still treat it as an HDR exposure sequence and only generate control points between images having the same exposure.
  • OpenCL intialization failed on AMD 5700X GPU (and possibly other recent AMD GPUs too), preventing the use of GPU acceleration.
  • A fresh installation of PTGui could occasionally have the tooltips disabled. To fix this for everyone, this update will always enable tooltips even if they were disabled previously. Tooltips can be disabled (if desired) in the Options / Preferences.
  • The option 'After sending projects to the Batch Stitcher: Close the Batch Stitcher when done' had no effect. It now works as expected. Still, this setting only has effect if the batch stitcher was not yet open. If the batch stitcher was already open (e.g. by using Tools - Batch Stitcher), it will remain open regardless of this setting.
  • Levelling a panorama would not work perfectly if the project contains viewpoint corrected images. PTGui now ignores viewpoint corrected images when levelling (provided there are at least 3 images without viewpoint correction).
  • PTGui would crash when loading a .png image with indexed colors (palette) and transparency.
  • A wrong compass angle (GPSImageDirection) would be embedded in panoramas stitched from Theta Z1 images.

You've got to be kidding me... Panorama Tools is a great piece of software: pity that some parasites try to make a quick buck by slamming an amateurish GUI on top of it and charging $100 for that. Hugin gives you a marginally nicer GUI, but has the huge added advantage that you will be able to spend your 100 bucks on a nice restaurant meal....

As of 01-24-2012, MacUpdate still shows 9.1.2. MacUpdate, why don't you have a button where we can EASILY inform you when your database is outdated? Been this way a very long time and it's ANNOYING that you have your users jump through hoops just to inform you of an update you've missed. Anyway... PTGui is up to 9.1.3 and it's been so for over a week.. Version 9.1.3 (16 January 2012) Fix: out of memory error could occur when saving large jpeg files on 32 bit Windows Fix: parts of the panorama could be missing in the detail viewer (detail viewer would show transparency checkerboard pattern) Fix: Area selection in Control Points tab (using Shift dragging) allowed the selection rectangle to be outside the image bounds, resulting in several problems PTGui can now save JPEG files up to 65500 x 65500 pixels. Previously this was limited to 25000 pixels width and height. Please note that many applications (including Photoshop) cannot read such large jpeg files, claiming that the file is corrupt. Creating progressive JPEG files is no longer supported

We're working on improving the ability to communicate with us. You can always email updates@ and just mention in the subject "[App Name] [Version #] is out" or a similarly simple/clear message. Bonus points if you include the link to the app in the body of the email :) Thanks for your support!

My review of 2 years ago is still accurate. This is a serious piece of software for the professional. It has been continually and frequently updated over many years. I have been using it for about 4 years. Note that it is not just a GUI for Panorama Tools, although it started out that way. It has its own stitching and blending engines now, but the user may select open source engines as well. That said, I believe one should not disparage a program that is principally a GUI if it makes a complicated tool easier and or faster to use. After all, Mac OSX is at its heart a GUI for Unix and learning new tricks in photography is a lot more productive for me than learning the command line interface for Unix. For the causal user there are cheaper stitching tools and Photoshop itself keeps getting better and better but when you need a high degree of control over the process and results I have found nothing better than this software.

I'm a pro shooter and I've been using PTGui for at least a couple of years now. I'm very surprised that there are no reviews of it here, so I am going to pipe in. I love this app! I have seen it mature with many updates. This is a very powerful app with a huge amount of control. The interface is somewhat daunting but worth the effort. Originally, the app was a Graphical User Interface that ran the Panorama Tools engine (hence, the name PTGui) written by professor Helmut Dersch. It has since gained its own engine but can still use professor Dersch's engine. To be fair, the stitching engine within Photoshop has also matured into a great tool and for many people will be entirely satisfactory without purchasing a 3rd party app such as PTGui. Photoshop's stitching interface works completely automatically and usually does a very good job. However, on the occasion when it doesn't work well, PTGui can get it done. PTGui is also my choice when creating a 180 or 360 degree VR. Id' write more but I've got to get back to work and make some money.
