REALVIZ announced the immediate availability of Stitcher 5.1 on Tuesday. Stitcher builds panoramic images out of individual digital photos. The updated version improves image misalignment detection, exports panoramas to .mov and .avi files for NTSC, PAL, and HD, batch renders panoramas, and supports external blending applications. Stitcher is available at the REALVIZ Web site, and is priced at US$580. The update is free to current Stitcher 5.0 users.
