I am interested in stitching some HDR RAW pano files. In reading the features of PTGui professional it appears that it will stitch pano images that are shot in HDR. Has anyone used this feature? I am especially interested in how it returns the final stitched image? Will this be file be in RAW which can then be corrected when opening in Bridge, or is the final file processed in PTGui and returned as a Tiff filel?
