D7000 with plenty of noise. No idea why

[cigarguy]

I've noticed very disappointing clarity in a lot of my photos lately and I'm at a complete loss why. I had to crank the contrast up in editing on this picture but it really highlights the problems I'm having. Help!

That one looks like you missed the focus. I would suggest shooting raw. JPEG only uses 8bit color depth whereas raw is either 14 or 16, which is better because it's more.

 

[cigarguy]

It was shot in 14 bit lossless but is it even possible to load the original photo?

 

[KmH]

No. You cannot post Raw files online.
The range of luminosity in the scene exceeded the dynamic range the image sensor could capture.

The highlights on her limns are blown out (over exposed) and what isn't directly lit is under exposed which make image noise more visible.

You needed to use a flash unit to correct for the dynamic range limitation.

It looks like you used Matrix metering. All that black in the scene biases the meter just opposite the way lots of white in a scene does.
But either way you get an inaccurate exposure unless you add light to balance the shadows with the highlights.

ISO 1600 i would not go over 800 with the d7000 for this sort of shot also F4.5 does not help you need to use way better lighting like KmH said or better lens something like a f2.8 or better the 50mm f1.8G is cheap like $200 and very good for low light shooting your just need to get closer lol

 

[cigarguy]

The funny thing is, the same problem happens in normal daylight and even with a flash on auto. Blown up to 100% its still far from a clear picture

if you say have settings of f22 and iso 1600 then yes this may happen even on auto mode at day time too. what was your setting do you have a sample photo with the settings you used?

 

[W.Fovall]

shoot raw. slow down shutter closer to 1/300, open aperture all the way. use a flash. using a higher iso is better than brighting in post...

 

[cigarguy]

I have to work on getting a good example but the last one was on auto, 1/60 f/4.5 and blown up to 100 w/o any editing there was noticeable spot scattered evenly around the picture. It was a horrible example so I'm going to try and use another one that isnt quite as textured

 

[W.Fovall]

don't shoot auto.. ever

[cigarguy]

Its happening on all settings.. auto isnt the problem. (trust me i dont shoot in auto) I'm basically just trying to eliminate any exogenous variables. Based on my results I'm thinking there's a sensor issue.

 

[W.Fovall]

looks like the image was dark and brought up the exposure in post?

 

[cigarguy]

In the posted image yes and it exaggerated the noise significantly

 

[W.Fovall]

yah.. that's normal for all cameras at that high of a iso.. adjusting up afterwards will always create more noise as noise is white so when you try and brighten the image you brighten the noise. when you shoot use the cameras light meter and shoot for slightly over exposed. its cleaner to darken a image then brighten in post
