Please help! Photo crisis D7000

Hello My name is Jesse . Ihave a big problem with my photos being really pixelated

in the black and darker shade areas of my photo . even happens at low iso"s of 200-400

In the middle of the day i get this tacky pixelation in the shaded or black areas of my photos. Yes ther shot in j peg . My D70 never had this issue . i was stoked to get the 7000 but now im starting to wonder and disapointed after all the hype about this camera .

Im hoping its just my pc resolution or a simple setting . or could this be a bad censor??

Please give me any idea possible . this does not look good for my customers .thank you

Hi Jesse it would be better if you post a 100 percent crop of the raw file with the exif data for evaluation in the area you see the pixelation.

According to the EXIF data, 1/13 sec., f/3.5, ISO 2000 (two thousand, not two hundred), 18 mm, exposure comp -0.333333, no flash, sRGB.

It must have been pretty dark when the image was taken. The histogram is jammed against the left edge.

One of the local pros says "bright pixels are sharp pixels". Another one, who's blog was linked recently suggested that having a right weighted histogram provided a lot more data than a left weighted histogram. You have a left weighted histogram, in a JPEG, worst of both worlds according to some.

You could get the same look by shooting a brighter image as a raw file then reducing the exposure in the raw conversion. This would let you keep the detail in the dark areas as there is much more control on the computer. When you take a JPEG, you are allowing the camera to grab a slice of data from the middle of the sensor data, and throw away the rest. It throws away much more than it keeps for your photo.

There may be differences between the D70 and D7000. If you still have the D70, set up a scene where you have control over the lighting. With all the same settings on both bodies, take a picture with the D70, then the D7000. Compare the images. If the D7000 is obviously off, send it for repair.

Jesse

CameraClicker has given you the correct answer.

Nikon has one huge problem when using the camera higher than ISO 1600. If you set the camera with exposure comp set at -3 exposure compensation, you will get "NOISE" in the photograph. With Nikon when using high ISO always meter correctly and leave the exposure compensation at "0" that way the sensor and "Expeed 2" will give you a shot that is relatively clean but there will always be some noise in the shot because of the high ISO.

Jesse,

as i now reloaded my exif viewer into Firefox i can see the 2000 ISO which will give you noise to some degree period..

One thing you should know about the D7000 is that it's advisable to shoot Raw as in most cases it'll expose to the right. Which in itself is not a bad thing, but unwise when shooting Jpeg (especially with 'Matrix metering') as there's not much you can do with the 'cooked' result.

Noise is comparable to any other camera in that price bracket:

I dunno what the mix up is with your iSO in the above image, did you leave both exp comp and Auto ISO on from a previous shot?

It would be better to upload an example where as you say, you are seeing noise at 200 - 400 ISO

If you have active D lighting on you will get more noise is shadow and under exposed areas.

Adding more sharpness will make it noisier, if you want the image to look sharper then turn of the noise reduction.

As for noise in the image, I'll say that it looks about right, if you had the image exposed properly then it would have not looked that bad.

And Fred.

Nikon has the lowest noise at high iso then any other brand.

Totally agree with you Anatoliy,

nothing betters the Nikon D3s in low light shooting..

To reduce noise switch off the sharpening in camera and apply later as the last editing step on your .tiff file.

Shooting in Jpeg will not help you in the noise department.

I have just downloaded the picture and had a good look at it. I will start with the EXIF Data

1/160, f/8, ISO 500, Lens length 27mm, Matrix metering, No flash, White Balance unknown, Scene Capture Type = Standard, Gain Control - Hard-2, Subject distance= UNKNOWN

A few problems

1. All the white around the window in the top left is overexposed, no detail.

2. The shadow areas are under exposed (where the noise is)

3. White spots in the shadows, this could be caused by dead cells on the sensor, easily mapped out or it was light shining through the holes.

4. SUBJECT DISTANCE= UNKNOWN. This means the camera fired even though the lens was not focused correctly. You cna help stop the problem by carrying little LED torches. Aim one on the closed eye, Focus the lens, drop the torch, get the eye open and press the button. I always carry about six torches for low level light work.

So I am sorry to say a bad exposure.

See what the others say about this.

I have tried to recover some of the shadows and highlights but it is not very good

i understand .... In my photography i dont aim for proper xposure most the time . i prefer blown out whites for more artistic look in back grounds . intentional under and over most the time . at iso 500 i dont think i should get this kind of noise . would you call that noise? or pixelated ? i noticed i only get this were my debth of field is blured heavy . it does the same with the video . really disappointed with this camers rt now . or could it be a memory card ? im going to compare shots with my d 70 and d 7000 same settings and go from there . this is bull . been shooting 3 yrs and my 70 never had this issue . c mon nikon wtf . no need to respond im gonna go to nikon if my comparison between the 2 is off . Iwant to thank you all for your time and info . i did learn alot still. : ) thank you
