Digital camera noise reduction idea

Dec 02, 2007 5 Replies

I was curious if anyone has thought of the following way to reduce image noise, in particular noise that comes from an electromagnetic source i.e. not light. The idea is, just cover most of the camera with tinfoil, everything except the lens of course. By this method, the only signal noise that affects the analog sensor elements will be of either internal origin (the circuits) or optical.



But will it work? I haven't tried it, since I temporarily don't have a digital camera.


It wont make any difference as the internal electronics are low impedance anyway.

The noise is caused by the semiconductor material not outside interference.

Part of it is also inherent in the incoming signal (because at low enough levels the photon's discreteness is important).

No, it will not work. A tinfoil hat on the operators head might be a more useful idea, though...

I think your tinfoil helmet has slipped.

If you are seeing images on the display caused by external rf, then you are holding a television, not a digital camera.
