When I take a photo with my digital camera - witout zoom - the pictures have so much grain. This only happens in closed places when the lights are on.

Is there any way to treat these images or solve this problem ?

1-what kind of cam is it?

3-Are there different settings for daylight, moon, etc?

Insufficient light will make a pic look grainy

Without seeing your photos, most likely you are seeing 'noise'. Digital photos have no grain. When in a less than ideal situation light-wise, cameras set to 'Auto' will adjust their ISO to a higher rating, (gain, not grain) usually incorporating some noise. Some camera are better at this than others. There are several programs that will reduce this noise, usually accompanied by a slight 'softness'. One such program is Noise Ninja. A comparison of various 'anti-noise' apps can be found at: http://www.michaelalmond.com/Articl...

Thanks for your messages. Actually my camera is Sony HandyCam (CamCoder). There is an auto settings for moon, light.. etc.

But, when taking photos under the light of any kind of light bulbs or white lights the photo has that noise or grain.

In case of taking Video with same cam the picture has that noise but, fewer than photos.

Alphawave is exactly right. The camera compenstaes for low lighting without a flash. Making the exposure too long will blur the pic, so it must set the ISO higher, resulting in the grainy look.

Thanks very much for help, I usually reduce that noise by using Adobe Photoshop CS2, and it cause some softness but, it's okay.

One more question:
Why the grain or the noise is fewer when I record Videos with that camera ?
