I'm a novice to photography and I'm wondering if its possible to combine multiple cameras to get a greater level of precision? I'm thinking that if you capture more light you should be able to improve the quality?
What is the name of this process?

overlaying multiple images from THE SAME camera (be that video or still) is a well known way to reduce noise (it normalises the image) or to gather more detail in low resolution images.
