Not getting the best from my D7000 as far as noise is concerned and wondered what others settings and workflow was. Always shoot raw and currently Adobe camera raw with noise on default setting. Shooting lossless raw 14 bit without in camera noise reduction. Noise evident even at ISO 200. Previously shot Pentax K20D with similar workflow and no noise evident. Please help :'(
 
definate some problem here. iso 200 on my D7K i can't see any noise at all ........
 
Okay, will do a straight raw tonight and post a crop. Viewing below 100%, so not really pixel peeping. Also had a secondary issue with my tamron front and back focusing randomly which I now believe is the VC ...

you may need to AF fine tune the lens on your D7000

I had this lens in Pentax mount and ut front focused but consistently, therefor afbfine tune as you say. This is spot on using focus test chart (tripod, so VC off), but I saw instances of both front and back focus in the studio on Saturday. Next test will be with VC off, Ken Rockwell suggests the VC takes time to stabilize, causing this.
Okay, think I have managed to put a sample in my dropbox folder, you can see the focus issue here, spot focus on left eye ... If you also zoom to around 100% you can faintly see what I am calling noise, this is not a great sample as I have done my best to correct this but all I have with me at the moment...

Found an iso200 sample and put it in dropbox folder as per above link. Look at the babys left foot, the "speckling" ...
 
i say that because i have a smimular issue with my 18-125 sigma, give a small amount of noise in my shots but my better quality glass doesn't so hopefully this is your issue too :)

The sample of the group is horrendous. I wouldn't worry about the baby's foot when there is so much noise visible in the blue shirt of the guy in the middle (and in the shadows on his face).
Have you processed that shot in any way and if so, how?
What does it look like SOOC?

Thanks, thought I was going nuts. Raw conversion with minimal fill, small sharpen ... Not good
 
I shoot professionally with the D7000 and have no concerns using iso 1600 when needed. I used to shoot exclusively raw with the D300 but have found jpegs from the 7000 so good only now use raw when I know extensive post editing will be needed. Has to be an in camera set up or lens problem.
 
Just how much fill did you add? Fill adjustment is an absolute nightmare for bringing out noise, possibly worse than using the exposure sliders. Plus, it looks about half a stop underexposed on the skin, which won't help matters.

You need to put the original raw file up so we can see it sooc....

OK, stuck up a couple of straight raw conversions, one at iso200 and one from a few months back with the same lens at iso4000. The ISO4000 one I printed as is at A3 and it was passable...
Going to have a play with the IS theory to see if this is a factor as many from this shoot definately lacked focus.
 
Cool :thumbs:

On the group shot, the SOOC one has a massive amount of flare wrapping the subjects. That's down to too much light on the background. Plus, it's quite underexposed - that background should be white, but in areas it's not. The noise is non-existent at this exposure but once you change the levels (to bring out the skin), it's going to bring the noise out, as in the original shot you posted.

The shot looks soft too. Might be the lens, might be the VC kicking in. I'd turn VC off in the studio - absolutely no need for it with flash.

The ailse shot doesn't look too bad - I don't have ISO 400 on my camera so can't comment :D

Sorry to say but this is probably user error in the first case regarding the noise, not kit error. :)

Agree, lights were set up bad at this stage, teach me yo forget light Meyer ! Also agree that no need for VC in this situation so definately need to try with it switched off.
Thanks, hopefully it is user error :-)

Just checked lens on focus chart again and ut is now backfocusing, need to keep an eye on it as it was perfect a couple of weeks ago. Anyway, suppose that's what the fine adjust is there for !

Fine adjust - I don't have that either. My camera is showing its age :lol:

Thats not an issue if you dont have to skimp on the glass ! Seriously, it is a handy tool ... one of the reasons I did not consider a 60D
 
I have the D7000 with the stock 18-105 lens and also the Nikon Fisheye....both are absolutely fine without any noise showing like you describe but I'm not using any studio lights etc.
