Posted this at DPR, too, but lately there's nothing but fighting going on over there. Not sure if I'll get a real answer, so here goes at mu, too Does anyone know how/if the Noise Reduction and Noise Filters interplay with each other? From the EPM1 manual (p85) Noise Reduction: "This function reduces the noise that is generated during long exposures. [Auto]: Noise reduction is only performed at slow shutter speeds. [On]: Noise reduction is performed with every shot. [Off]: Noise reduction off. • Noise reduction requires about twice the time needed to record the image. • Noise reduction turns off automatically during sequential shooting. • This function may not work effectively with some shooting conditions or subjects." Noise Filter: "Choose the amount of noise reduction performed at high ISO sensitivities." I can make guesses and conjecture at what this means. I'm wondering if anyone here has done testing or somehow else actually KNOWS how/if these two settings interact? For instance, do you need Noise Reduction ON, and then Noise Filter controls the strength? If they are independent, then how do they differ? Thanks for any help/insight.
