Night time noise query for landscape pics

    Hi all,
    I'm getting alot of noise in my nikon d300 pics at dusk or in twilight conditions. even with noise reduction turned on in the camera.

    is the noise level that high compared to weak light coming into the sensor?

    does anyone cope better with noise at this time of evening and get sharp pictures?

    or is using film better??

    Thanks

    Yeah, lower your ISO and use a tripod would be the first things to look at I reckon. If you're in a mode like 'night time' or something like that, the ISO might be set automatically by the camera! SO set to shutter speed, or aperture or better yet manual.

    I would imagine, as has been said, that ISO is your problem. From what I remember the D300 is pretty good for keeping the noise down so it's probably at a fairly high ISO. Drop the ISO and pop it on a tripod is your best bet.

    Although bear in mind that long exposures also introduce extra noise, but very little compared to having to whack the ISO up.

    The D300 does not have any scene modes like that. It is PASM only.

    I use a D300 and have no noise problems at night as long as I keep the ISO below about 800. I would hazard a guess that you may have the Auto ISO on and that will ramp up the sensitivity to try to maintain a specified shutter speed.

    Can you advise which mode you are shooting?

    What ISO is selected?

    Is Auto ISO on?

    Are you using a Tripod?

    Thanks for the advice guys.
    I was using tripod for the shots at dusk and ISO setting of 200.
    I didn't know that the high ISO contrubuted to the noise.

    I typically was using 10 second exposures and it was coming out very pixilated/grainey with the noise that was coming through the image.

    Will use differing ISO settings and see what comes out...

    Double check that long exposure noise reduction is set to on, on Canon its in the custom functions

    Another thing is if you underexpose the scene, especially in long exposure shots then when you are editing it afterwards the noise is much worse.

    Also you said the pics aren't sharp?? Make sure you have OS/IS/VR turned off on the lens when using it on a tripod. And if you are using a tripod then reduce the ISO to it's lowest setting, usually 100.
