![]() ![]() In the 'merge to HDR, then blend' workflow these linked images will be combined to a single HDR source image. In PTGui Pro 12, linking the images will tell PTGui Pro that they belong to the same bracketed set but they don't necessarily have the exact same yaw, pitch and roll. The purpose of linking images has changed: in PTGui Pro 11, linked images would get the same yaw, pitch and roll angles but linking did not otherwise affect HDR processing.The new workflow permits creating HDR panoramas from images taken in automatic exposure mode. PTGui Pro 11 and earlier would use the reverse workflow: create blend planes for each exposure level, then merge to HDR. New HDR workflow: Merge bracketed images to HDR first, then blend.The Multiband blending algorithm used in PTGui 11 and earlier is still available as an option. Combined with the new optimum seam placement this is able to create absolutely seamless panoramas even of busy scenes with many moving objects. No overlap is needed and pixels outside the seams are not used. New 'zero overlap' blending algorithm: blending is done by minimizing the exposure differences at the seams where the images meet.Also, stitching errors from parallax will be hidden as much as possible. It will attempt to automatically route the seams around moving objects. Automatic optimum seam placement: PTGui Pro 12 will analyze the regions where images overlap, and place the seams in those areas where there is the least difference between the overlapping images.PTGui 12 features a new and improved blender, automatic optimum seam placement (in the Pro version) and much more!
