6d and noise

My new 6d just came about a week ago, and not much time to play with it yet. Anyway, I just snapped a few picks of one of the kids here that day at iso 640 raw and I notice noise in the dark area's even at that low iso.

Does the 6d only apply noise reduction too jpegs? Or am I missing a setting somewhere that needs to be set for raws?

Thanks for your help

You are making too much noise.

The 6D has so little noise at ISO 640 it's not worth running a filter on... Make sure you expose properly.

Could you post a photo?

Long-exposure (subtractive) noise reduction, where the camera takes a blank exposure after each image, affects raw images. Other in-camera noise reduction affects only jpegs.

The 6D should have very little noise at low ISOs if you are exposing properly. I shoot a 5D3, which is not quite as good in terms of noise as the 6D, and it is very clean in properly exposed shots at low ISOs. All cameras will have more noise in the shadows because the amount of signal is very low and the amount of noise is the same as it is in bright areas.

You should post an image for more specific feedback.

I believe your right, it is in the shadowed area so that would explain it. I guess I just wasn't sure if this was normal for this camera, I was expecting not too see any noise I guess even in shadows. Also, in lightroom I did up the exposure on her face a bit which wasn't bad to begin with...so you were also correct, it was underexposed a little and by doing so it was able to lighten the shadows a bit, but the noise is still there but not drastically.

I also noticed sharpening was on in lightroom for the picture, so that was making also making the noise more pronounced at first look of the picture when uploaded.

Maybe the key here for me is to expose too the right a bit more, I normally just stay right in the middle bar for the meter reading.

Thank you all so much for all your help, I'd rather the problem be me then my new camera...love my Canon 6d..just need time to run it more.

Exposing to the right will help, so long as you don't go off the right hand side with anything significant.

Simply sitting right in the middle for the meter reading all the time, is no guarantee that the exposure is correct. Depending on the tones in the scene, "correct" exposure could easily be a up to a couple of stops either way. In addition, Canon sets its cameras up to slightly underexpose if following the meter reading (or using any auto/semi-auto mode without EC) in order to reduce the risk of blown highlights. Many people like to compensate for this by always setting 2/3 stop +ve EC for their exposure. Personally, I don't have a simple EC modifier I stick to at all times, my exposure can be a stop or two below meter or up to 3 stops or so above the meter reading, depending on what I am shooting and the tones I am metering off. I am more likely to have a little +ve exposure dialled in than be in the middle or -ve end of the scale though.

It is probable that the reason your image was slightly underexposed is simply that you used the unmodified metered reading and got the slight built in underexposure.
