I have seen this before from my Z10, but never from my D3000. The picture was taken at iso 200, 1/60 F4.5 I think.
I had my flash mounted and was aiming at a light part of the wall close to the ceiling.

Look at the woman to the left. There are redish stripes running up her dress and the shot was very noisy. Other shots were taken in the same conditons only moments before and after--in the same spot. But they were fine.

Looks to me like her dress has red woven stripes in the material with a lot of texture. Check with her to see if that is the case and go from there. There may not be anything wrong with your camera.

There may not be anything wrong with the camera. Our eyes are amassing they can correct color, focus and adjust for difference in exposure and may more things. The camera cant. When they say a camera dont lie, there is some truth in it. These red stripes may be in the material but we cant see it with our eyes. Try taking another picture with similar light of her dressed the same. I would be interesting to see if it does it again.

When I enlarge the full-sice image, I see the red in the woman's hair, the wall above her, and in man's shirt (collar on the left side) as well, though it is not as prominent. Im wondering if it is simply noise.

Are you shooting raw or JPEG? What was your workflow?

A close look at the man's collar shows the same discoloration. Interesting problem. Let us know if you find the problem.

ironically, there is another thread with this same problem but with a d-40. poster is from the uk.

You have what could be color banding in the color of the dress and the man's shirt. That's usually a result of overly-compressed images. Try re-opening the file, and Save As with a lower compression. It's a processing problem, not a camera problem if it is color banding.

Wow, just imagine if photography were just about the camera.....I was born too late....

The problem is present in the NEF as well. For some reason it looks a little better in PSP than ASP for some reason.

I compared the EXIF data from a shot that was taken seconds later. The bad shot was taken at 42mm 1/60 f4.5 ISO 200. The good shot was taken at 18 mm 1/60 f3.5 ISO 200. A Nissin DI622 MK 2 was used in both shots and was aimed to my right. The ceiling of the porch area is wood, but there are arches that are light--I usually aim for those.

Zooming into the bad shot shows that the entire image is full of hot pixels. Seems like I really under exposed and the light wasn't strong enough to light my subjects. Funny that I didn't shoot in manual mode--I was screwing around with portrait mode.

Looks like Moire to me.

Had a problem similar to this many years ago never figured it out until the problem occurred again and found that it was a red striped table cloth that was the culprit, the flash was reflecting those red stripes onto black surfaces, did the same shot both without the cloth and bouncing the light off the ceiling and results was no stripes put the table cloth back and yup there was my red stripes.

Not in the fabric: red bands are straight, not following the flow of the material over the body. Banding would make sense if it were all in JPEG. But in NEF too?

I think the TTL metering was fooled because of the large % of white in the wall behind them, which tends to under expose white to a more gray. That would under expose the whole image. Were you on spot meter, or evaluative?

Underexposed would esplain all the noise. As far as the banding, I would tend to believe that it is in the processing of the underexposed image. I've gotten wierd flare type results when my SB600 doesn't cycle fast enough to fire, and the shot is underexposed, once I try to lighten, even in Raw, I get some funky things going on with noise and other stuff. Yours just isn't quite that underexposed.

I sure hope my guess helps.

Just reread my post.... did I mention that I think you are underexposed? :oops:

I have never had the color banding but I have had the intense noise on occasion. Similar shots before and after were OK. No good reason for the noise. My computer does unexplainable things frequently, since my 50D is just a computer with some glass I guess it will do the same thing. Fortunately it doesn't happen often. I am interested in others experiences.
