Spatia...If it's random, it can't be known.<br /><br />Spatial aliasing is a fundamental, intrinsic feature of digitization and it affects all analog to digital signal conversion.<br /><br />You are right, it is not possible to know what is an artifact (moire) and what is not after the data is recorded.W.

How about adjusting the colour of the light before the sensor records it - for example if the light is really blue, the sensor is using a very small part of it's capabilities and in adjusting the colour, the raw processor has to magnify the signal from the areas that should have been warm colours much more and there is more noise. Now you'd get a good balance before processing and minimum noise.<br /><br />George<br /><br />GeorgeGeorge Barrhttps://www.blogger.com/profile/06745541057122821349noreply@blogger.comtag:blogger.com,1999:blog-27557058.post-11004411871368432062010-01-23T15:15:48.270-07:002010-01-23T15:15:48.270-07:00Not only could you vary the filter color of each p...Not only could you vary the filter color of each pixel, you could have variable neutral density for each pixel- making possible both long exposures and compressed contrast for adaptable dynamic range.
