Otherwise, what is the point of having more pixels?Returning to the raw conversion theme, I've just tried comparing the noise on an image converted with DPP with the previous ones which used PSE6 and the latest version of ACR (5.4). To my considerable surprise the DPP noise levels are noticeably lower than with ACR - roughly half a stop over most of the grey level range! The difference was even more marked in the dark image areas (<50). See attached revised graphsAny ideas anyone why?</blockquote>
