3DVista Stitcher vs PhotoPad

3DVista Stitcher 4 turns groups of photographs into panoramas through a guided, one-click workflow. It accepts standard, wide-angle, fisheye, and one-shot lenses and most popular camera types. Outputs can be full or partial panoramas in cubic, spherical, or small-planet forms, with 18 projection types including equirectangular, rectilinear, cylindrical, and small-planet. Automatic control-point detection helps align images, and you can add, move, change, or delete those points. One-click standard HDR and Adaptive HDR stitching are included, as is batch stitching for multiple panoramas. Stitcher can process 3DVista Live Panoramas and Adaptive HDR Panoramas; publishing those as immersive virtual tours requires Virtual Tour Pro. The software runs on macOS and Windows, supports HDR blending and control-point editing, and does not support RAW input. A free trial is available.

PhotoPad edits and enhances digital photos and images, with tools for cropping, rotating, resizing, retouching, and adjusting color and exposure. Blur and sharpening controls complement its non-destructive editing: users can undo, reorder, or change effects in a layers list. It can also make collages, photo mosaics, calendars, greeting cards, and photo montages. The maker lists AI-assisted super-resolution resizing, object and background removal, and colorizing black-and-white photos. PhotoPad supports RAW editing and formats including JPG, GIF, PNG, TIFF, and BMP; HDR/exposure blending is also listed. A project can contain up to eight images, and panorama types include wide. Edited pictures can be uploaded directly to Twitter, Flickr, Dropbox, OneDrive, or Google Drive. It is listed for Android, iOS, Linux, macOS, web, Windows, and as an extension. The free edition costs nothing and is limited to non-commercial use; no signup is required. Desktop requirements are Windows 7 to 11 or macOS 10.5 or later.
