[QUOTE="Felisek, post: 472052, member: 23887"] There is a hard physical limit to which you can improve sensor sensitivity. It is counting noise. When you have only a handful of photons arriving per pixel (and as J-see mentioned, pixels are getting smaller), there will be Poisson noise in the final image, whatever smart technological tricks you apply it. This is basic physics (or rather statistics) and you cannot beat it. [/QUOTE]
