PTGui is a panorama photo stitching program for Windows and macOS developed by New House Internet Services BV.
PTGui supports telephoto, normal, wide angle and fisheye lenses[4] to create partial cylindrical up to full spherical panoramas.
[6] The 'free trial version' of PTGui is fully functional but creates panoramas with embedded visible watermarks.
[8] The upcoming version 13 beta 8 - though as of Nov. 2024 still slated as beta status, is now reported as quite reliable after 8 iterations - includes the following new features: a Patch Editor (PTGui Pro only), DNG output, improved RAW / DNG handling, and JPEG 2000 support.
[9][2] Version 13 beta 8 also claims significant performance improvements when optimizing large panoramas and also a speedier optimum seam finding algorithm.
