PTGui panorama photostitcher
Most cameras come with a free photostitcher, but I use a commercial one called PTGui. Originally built around “panorama tools” (a free suite of programs and libraries), but has since relied on it’s own engines. It can stitch photo’s taken in a typical horizontal fashion, but also in a matrix (both horizontal and vertical). It will automatically match and blend them. A demo can be downloaded, but the actual price will be $119 for the personal version and $225 for the pro version (which includes batch processing and support for 64 bit windows and HDR images). I haven’t been able to justify the $110 difference (yet.) You get updates for 1 year after that the update (rather pricey, I thought) is $38 for standard PTGui and $68 for the pro version. Price aside, if you take a lot of photos of landscapes and such, take a look. I use it and recommend it. In fact, if you look for the tag panorama on by blog, you’ll see a fair amount of pictures using PTgui
