    One thing I've noticed with the E-PM1 is that it seems like it has a lot of noise in the shadows. It almost looks like I pushed the shadows in post processing. Most of the noise seems to be concentrated in the red channel.

    Here is an OOC jpeg. Notice how noisy the black areas are. This shot was taken @ ISO200 1/3s F8.0


    Same image where I played with the contrast and brightness to crush the black levels back down and the image looks much batter. Not sure if this is the best way to go about getting rid of the noise but for this particular image it worked really well.


    Is this something that I am just going to have to take care of in post? Will adjusting the tone curve reduce my shadow noise?

    BTW when I look at the image in my LED back lit LCD the noise just jumps out at me but when I look at it on my really old ~7yo LCD I can't really see the noise... maybe I just need to stop using the newer LED backlit LCD :)

    The older PEN sensor had a ton of read noise so even at base ISO, shadows were pretty noisy. If you look at the RAW, much of it is chrominance noise which can be handled with noise reduction. Some is luminance noise and in many cases, reducing luminance noise reduce fine details.
