7D noise reduction in Raw
Feb 18, 2010

I have been playing with the 7D for a few weeks now. I have read the manual front to back about the image and autofocus settings. I prefer to apply noise reduction after the fact ...( like i do with the 5DmkII) ......so i set all noise reduction in camera to "deactivate" setting and all NRsliders in DPP at 0 by default. Still i can see what looks like noisereduction in all my raw files when i look at them at 100%.Noiselike pixels spread randomly near high contrast edges. Its not only at higher iso values that this is visible.....you can even see it at iso 200. At 50% magnification they are invisible but the photo's do not show the finer details like 5DmkII files do.

Is there a way to completely shut off noise reduction ....or is this set at factory and not correctable.
