I haven't looked at this software before so will do later. If the camera and scene remain unchanged, I think it would be tough to extract any significant extra information out, although you will get reduced noise. To potentially get extra detail out, some slight camera movement between each shot would be useful I think, so you can sample the same scene with a different pattern.



I have used stacking a lot for noise reduction in astrophotography. Total exposure times are typically in the hours here, and I still need more data to get the noise down! I'm not sure if the software I use does any clever stuff for resolution improvement though, but my less than perfect tracking means I do get pixel shifts which handily mask the effects of hot pixels. Far more features in the software than I've figured out so far...



On the medium format thing, I do recall reading about one system which could offset the sensor a pixel at a time and capture 4 images, so that you offset the bayer pattern and get full colour information at every site. Of course you need the scene to remain static while it does that...
