Taking multiple partial shots and stitching them together can significantly increase the amount of information extracted from a negative. There are two questions (for me, at least):
Common wisdom suggests a 30% overlap between partial shots. If one is stitching a MF negative with (say) a cropped sensor camera, that might be as many as 6 shots or more. Do you go top, from left to right, and then bottom from left to right? Or what is the most effective way? Or, can one shoot only the upper (or left) half and stitch that, and then the lower (or right) half and stitch that, and then stitch both halves?
For the purposes of just stitching the shots together, is any stand alone software (such as PTGui) inherently better than the stitching programs within LR or PS? What makes a particular stitching program “better,” if all one is trying to do is stitch the photos and afterwards process them in LR or PS?
