With a tripod to stabilise a camera, is it possible to get more detail through multiple shots? Just averaging the noise would smooth things out, but I wonder if there is any more intelligent processing that could improve things. More shots could (in theory) provide more data.
A similar problem might be to try and improve the resolution of a single hand-held photo, shot in normal lighting conditions, by taking many pictures in rapid succession and then processing them. Each picture would be in a very slightly different position and so (again, in theory) might provide more data?
No, you can only get cleaner data and maximize the pixels you have, not more effective pixels. The way you could get "more" data is to simulate, say, a 28mm equivalent lens with, say, multiple shots from an 135mm equivalent lens at different locations and stitch them together.
Thats what they do when you see those 3GP+ shots you can zoom in on.
You an absolutely gwt subpixel detail by averaging multiple photos taken with the same setting with almost exactly the same frame. I had software in 2004 that did this, converting short video to high res photo
