I have gone through the following explanation on Canon's site:http://web.canon.jp/imaging/cmos/technology-e/size.html, but struggleto understand how a single pixel can get more information than asmaller pixel..
It doesn't get more information in the sense that there is more detail in the image or so, but it catches more light so the signal to noise ratio is better. That means you can say the information will be *more accurate*..
Surely noise is related to the input, not the device itself....
One possible if not major source of noise is electrostatic discharge. Under controlled conditions, I have noticied differences in luminosity characteristics between consecutive shots (as observed in the Capture NX histogram palette). If others of you could supply additional explanations then that would be great..
But really it would be beneficial to treat the dslr like you would treat your cpu cards until the facts are in.-Garrisonhttp://www.umefotographie.com..
So 10l of waterhas 300ml of noise, then surely 100l of water will have 3l of noise??The ratio is still the same..
As the photon signal increases by X, the noise is increased by the square-root of X. So if 10L of water has 300mL of noise, 100L of water has 948mL of noise..
The ratios are not the same...
To those of you who replied, thanks, to those who have read it, and need a good explanation, I came across this, which to me explains it brilliantly..
Thanks all, and happy snapping!! .
Trigger Happy! ..
I am thinking right when I compare CCD size to standard film size?IE: 35 mm better than 110 because of the idea of 35mm needed less blowing up?Or is it another reason all together?.

In a way, yes, it is pretty similar. In fact, that might be the easiest and best way to explain the whole thing...
