"The SNR indicates how much noise is present in an image compared to the actual information (signal). The higher the SNR value, the better the image looks, because details aren't drowned by noise. SNR strength is given in dB, which is a logarithmic scale: an increase of 6 dB corresponds to doubling the SNR, which equates to half the noise for the same signal.

An SNR value of 30dB means excellent image quality. Thus low-light ISO is the highest ISO setting for a camera that allows it to achieve an SNR of 30dB while keeping a good dynamic range of 9 EVs and a color depth of 18bits."

so actually it is an ISO speed,

Thank you. That is even more informative than the response from ezstrobe.

But, as with my response to him, it would be even more help if I could see the entire graph for these cameras. That would tell me something about how they reacted to decreasing light over the entire ISO range.

Does DxoMark publish these graphs? Or only the one specific figure?
