I just posted this on another thread but I think its also relevant here as we consider the pros and cons of having lower noise files.
"You're right that small sensor cameras tend to have more limited dynamic range. And this is another area in which having a lower noise file can help. In photography of dynamic subjects, the only way to hold the highlights with these cameras is to expose for them. That may often later mean digging into the shadows a bit to recover detail. The further down in the shadows the noise floor is, the more flexible the file will be for this process."
In essence, the usable dynamic range a camera has increases if its files are cleaner. Why? It increased because one can recover more detail from the shadows while still staying above the noise floor. The noise floor, of course, is the level at which digital noise starts to replace shadow detail.
Cheers,
Sean
