His chart claims that a D3100 has 0.0 read noise!
That should give a clue as to accuracy / credability.
Why, you have your own data from doing the same measurement with a D3100 sensor that contradicts it?
Or you have another source that you can cite to show that it is wrong?
No, I didn't think so.
Is one necessary? If I told you that I dropped a penny and a bowling ball off the Leaning Tower of Pisa, and both of them flew straight up into the stratosphere, would you need a source to prove I was wrong? 0.0 read noise is an electronic impossibility (if it had stated below the LLOQ, or something similar, fine, but not zero).
First, "0.0" is not "0". Second, it could mean LLOQ, but I don't know enough about the method, etc.
Generally speaking, if you want to criticise someone else's results of a scientific method then you do so by doing your own experiments that prove your point. And yes, I'm willing to bet that the method DxO use to generate the raw numbers that goes into those calculations and the method of arriving at the calculations in that table is a lot more scientific than the process of saying "That 0.0 is wrong and because that 0.0 is wrong all other results lack credibility."
Further, all of the results (except for that line) seem completely reasonable which tends to suggest that there is more than fiction behind them. If it was Ken Rockwell posting this information then I'd be extraordinarily suspicious. But it isn't and more to the point, the page is free of ads so quite clearly there's no need by the author to generate lots of page views by creating sensationalist content.
Finally, as the "About" page says (http://www.sensorgen.info/Calculations.html
), all of the calculations are based on DxO data. If the "0.0" seems outrageous then you're free to download the data for yourself and see if the published methodology confirms that "0.0" is correct (or not) and also to contact DxO and challenge them on the accuracy of the data for the Nikon D3100 or even start threads all over the Internet about how the true extent of Nikon fanboy-ism at DxO is revealed by results that are obviously bogus for the D3100.
