    You're using an ISO of 1600, try lowering it to around 400. My 10D also has a lot of noise or "graining" above 400 ISO so it could be the same problem.

    yeah me either. noise comes from long exposures and high ISO's. there is a noise reduction option on the d50, use it it might help.

    PS. How do you view exif data on firefox?

    Im going to say its your monitors - because those definitely are rocking some noise. I'd say its because of the close crop on the last two, but he's using a 50MM, and definitely the first one doesn't look like its been cropped that much. I'd check the ISO setting as was recommended and try and keep it 300 or below. Hell with a 50MM you should be able to just drop it to 200 and leave it there.

    I keep my D50 on 200 almost always and rarely to 400... although these don't look too noisy.

    The last picture:

    File name: DSC_0359-1.jpg
    File size: 366800 bytes (3008x2000, 0.5bpp, 49x)
    EXIF Summary: 1/1250s f/2.8 ISO1600 50mm (35mm eq:75mm)


    Drop your ISO, noise goes away.

    And then use the Opanda Firefox plugin :p

    Asside from the mentioned high ISO problem the other thing is noise is typically buried in the shadows. Think of the analogy of a really quiet tape recording (you do remember tapes don't you?), and turning up the volume brings out more noise than a loud one. Well if a photograph is dark and you bump up the shadows by decreasing contrast or increasing brightness you amplify the noise.

    Welcome to the world of shooting indoors. Get a tripod, shoot at f/1.4 at ISO100/200, or use a flash :(

    Not only are the images noisy but Nikon is spelled backwards/reversed on your camera. Can't believe Nikon let it out of the factory badged that way.

    Acutally, the Nikon spelled backwards is a problem that is largely ignored by the company... I see a lot of it in their "Stunning Nikon" ads... a whole bunch of people holding up cameras, shooting and the Nikon name is backwards.

    Perhaps this is a new effort by the company to insure backwards compatibility?
