OK Crazy idea time, I am aware that the G3 takes two photos when taken in low light at long shutter times (not sure the actual figure), one is with the shutter closed and is uses to work out what the noise is in the actual image to remove it.
This is cool; however can this be done manually? I quite often shoot in low light conditions, and cannot use a flash, due to the distractions it creates, to get reasonable exposures I need to run at ISO 400, however as a result of this I get a fairly high level of noise. Is it possible to take an image with the lens cap closed to create a 'noise reference image', so I can then use it in Photoshop or similar to remove the noise?
My understanding is that the noise levels are not consistent, so one of these images would probably have to be taken each time I shoot.
Any thoughts?
(Buying a EOS300D, as it suffers from less noise is not a valid answer for me, way out of my budget!)
