Photoshop doesn't do anything automatically... so what you're saying is that it does better job than someone manually doing in Photoshop? that could offend PS Pro's around.

I use my DSLR for pano shots, but since it doesn't have any preset/assist mode for pano. What I usually do is use wide lens and crop (no stitching software can beat that )... or else remember end points to match with concluding shot and use Exposure Lock to prevent the exposure to vary in different shots due to different lighting... and off-course manually stitching/composition of final shot in Photoshop. So far I've got pretty good job done in photoshop!!
