Coping with images that have atypical noise
Posted: Sun Apr 16, 2006 6:17 am
It looks like Neat Image only uses one noise sample from an image (using the auto-profiler) to measure the noise characteristics. My concern is that all P&S cameras these days have NR in the camera (sometimes pretty sophisticated) and the resultant images might have unusual noise characteristics--I've even seen cases where the signal-to-noise ratio is actually higher in bright parts of the image than in dark parts. The camera might also do odd things to the noise depending on the color in the local part of the image.
My question is, how does Neat Image cope with "wierd" noise like this when it is only sampling in one part of the image. Is there a way to get it to take multiple samples? Please enlighten me!
