Here is a neat idea on how to improve images using median evaluation.

1. Shoot a number of pictures (at least 10) using a tripod (so that the images are accurately aligned). Let us say that the numpy objects are in a list obj
   
2. For each pixel position+color (a,b,c) look at the values of obj[n](a,b,c)/8 as n varies  and assign new(a,b,c) to be the 8 times the value that occurs most often (mode) in this sorted list.
   

Now view new as an image and prepare to be amazed at the improvement!

One more thing to try. Do a time elapsed series of photographs where some objects (say people) are moving in the foreground. With enough pictures, this approach may get you only the background and remove the moving objects.
