PTGui is an application that helps you stitch any number of photos into a panoramic image.

· Create spherical, cylindrical or flat panoramas from any number of source images.
· Fully automated: create single row, multiple row or fully spherical panoramas in just a few mouse clicks.
· Realtime preview of final panorama: you can instantly see what your final panorama will look like.
· Panorama editor for visual and interactive parameter editing: Move your images with the mouse to change yaw, roll and pitch parameters. Perspective is corrected in real time.
· PTGui can stitch HUGE panoramas! Stitching 200 images into a multiple gigapixel panorama is no problem.
· Fully 16 bit capable: PTGui suports a 16 bit workflow from start to finish, for the best image quality.
· Layered output: PTGui can create multi layer Photoshop files, for flexible post processing.
· Reads EXIF information from images produced by digital cameras, to determine the lens parameters.
· Create templates with frequently used settings (you will find some here).
· Batch stitcher: prepare any number of panoramas and stitch them later without user intervention.
· Create a printable PhiloSpere of your panorama.

Limitations:
· Stitched panoramas will have a visible watermark
· Projects cannot be saved or exported
· 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

What's New in This Release:
· PTGui Viewer: supports gyroscope navigation on the iPhone 4. Look around in the panorama as if you are really there by rotating the phone.
· PTGui Viewer: on touchscreen devices (iPad/iPhone/iPod) panoramas are now navigated by swiping instead of drag and hold
· PTGui Viewer (Publish to Website tool) now supports WebGL. This means that Flash is not required to view panoramas in the Safari browser, Chrome 9 browser and the upcoming Firefox 4 browser.
· PTGui Viewer: the Full Screen button can be hidden, or it can be shown only when using Flash
· PTGui Viewer: double click to switch to full screen mode
· PTGui Viewer: increased default size limit for Apple mobile devices to 4.5 megapixels; recent versions of Apple iOS can safely handle panoramas of this size.
· PTGui Viewer: Fix: on Apple mobile devices the panorama was shown at only a low resolution, until the user switched to fullscreen display
· PTGui Viewer: Fix: entering a negative value for autorotate speed (to rotate towards the left) ...
