"How do I get rid of noise with my D40?"


US
          

I've noticed that my pictures come out with 'noise' or 'grain.' I'm not sure what the proper term is, but they definitley are poor quality. I don't remember my camera ever having this problem. If anyone could help me out I'd appreciate it! My pictures look so gross now I don't even have the will power to go out and photograph

You say you do not remember having this problem..so has anything chnaged? A new lens..shooting style( as in you used to shoot all landscapes now you are shooting macro) You checked your exif and you do not have some setting changed from 'before'? Also would help if you posted some examples..We need a little more info

I have the regular lens that came with it. And I have a 70-300mm f/4.5-5.6. I don't think anything in particular has changed. I've recently started to change the settings on my camera. I'll post some photos in a bit.

Hi Megan,

Noise is usually a result of shooting at high ISO settings.
Is the ISO set higher than 800?
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

It's set at 200. Could it be that my camera sensor needs cleaned?

Hi Megan,

Dust on the sensor shouldn't look like noise or grain.
To check the sensor for dust, stop down the aperture to f/16 or f/22 and aim the camera at a blue sky and capture an image. Dust and dirt on the sensor will show up as black dots or dark blotches.

Under exposure can also cause noise. Is the noise in the darker areas of the image or across the entire frame.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Tell us a little about subject matter, shooting conditions, post processing etc.
Are you shooting in a very dark atmosphere, or conditions where you're underexposing photos then correcting in post processing?
Even at low/native iso, dark shadow areas in a photo can show noise when exposure is corrected a large amount.
How many actuations has the camera taken? If its a huge amount, say over at least 50K while not likely, it could be a problem within the camera itself.
Does the problem occur with a single lens or with any lens mounted?
Dirty sensors don't usually show up as noise over an entire image, more so as ugly blotchy spots on a photo or specks of dirt showing as dark or miscolored spots, so while your sensor may well benefit from cleaning, a dirty sensor isn't likely to be the cause, or at least sole cause.
As mentioned, some sample images would be a big help in a diagnosis.

I guess a dirty sensor isn't the case, I can see the blotches.

How would I find out how many actuations it has taken? (I'm using the ViewNX2 if that helps)

And I would say it happens all the time, unless it's a gorgeous sunny day.

It's really quite depressing, I don't bother to pick up my camera anymore because my photographs are always very poor quality now! I really need to get this problem fixed

Post and example picture with all the EXIF data so that we can see what you are seeing and help diagnose the problem.

Those are the only ones I can find at the moment. To get the other one's I'll have to hook up my old computer which I'll have to do tomorrow.

To find shutter actuations, you can download the exif viewer from opanda.com and open an unedited jpg. Close to the bottom in the makernotes section there is a line referencing total shutter actuations. Lots of other data also pertaining to the individual exposure.

After using the download function to see the full size image on the bottom link you provided, what I'm seeing does appear to be noise but only in the light halo's around the street lights, a little on the rooftops in the background and dark sky.

I don't know if the D40 was plagued by this problem though the D80 had some heat related sensor issues during long exposures, and being roughly the same generation camera technology the D40 could suffer from some of the same issues.
If this were strictly an iso related noise issue it would be visible over most or all of the image and i'm not seeing that. The lit areas and even the darker areas in the foreground are quite noise free, on my monitor at least.

How about well exposed daytime shots in good light? does the same issue exist? or is it only in shots similar to the ones you posted links to?
Oh and according to opanda, the image in your second link shows your camera had 17315 actuations, so it should have alot of miles left in it.

I remember those two photos from a previous post.

Neither of those two pictures have much noise to talk about.

In general, to limit noise you want to use as low an ISO as possible to get the job done and not underexpose the shot. Often when using a higher ISO I will set an EV of +0.3 to help boost the signal to noise ratio then darken the image in post processing if necessary.

Areas of an image that are underexposed will have noise. The night images you linked to have a lot of underexposed areas, but I don't think the noise is objectionable.

Did you changed the auto iso? Try to switch it off and see if this make difference.
