I wanted to know if some of you know how it is possible to reduce or even remove the ISO Noise of Digital Photos. Because my cam is'n the best at low light capturing due to fast Iso noise creation. Would be great if you could tell me a few tricks or programs with that you can reduce or remove the noise but still don't need to photograph with ISO 50.
Please no Photoshop tips, tricks or tutorials because I don't have PS and it's currently not an option to buy it, don't have the money for that.
I prefer GIMP Tutorials and Tricks if you know some.

If you don't want noise, you need more light. Anything over ISO 400 is going to give you lots of noise. Use a flash, or a tripod. That's about it. Sorry. :(

Well you're right, but my cam is over ISO 100 already not-very-good anymore T.T and using a flash isn't always an opinion for example if I want to photograph at night some driving cars, it's dangerous if I would use a flash then because the driver could get shocked and build a crash. but thanks anyways for your help.

Looks like you're stuck with a tripod and a long exposure then. Without a high ISO, you're going to get grain. But without a high ISO, you're going to need a slow exposure. Photography has been this way forever. Unless you can design a new type of CCD, you're pretty much stuck with what you've got.
However, with slow shutter speeds at night, you get pretty cool light trails. Some very interesting things happen with long exposures. I've got some long-exposure dance pictures if anyone wants to see them. 1/2 to 3 second shutter speeds. nathansblogforclass.blogspot.com

Well thats right but I'm just jealous of the people who have a DSLR Camera because they have bigger lenses they can catch more light and make better pictures but I deceided to keep my cute black S500 and try to become a better photographer.
And the trick to take more shots of exact the same point to lay them together is a good idea, and it would be simple with my cam too because it gots a shooting setting where it shoots with +-0 brightness, -0,5 brightness and with +0,5 brightness and there you got 3 photos that could be layed together.
Thanks again, maybe I find someday a way to reduce the iso noise of my old pics without Photoshop, I hope.

It would be ideal if you can post more information about your camera and your photograph setting - ie what your camera is, what ISO, shutter speed, any tripods, etc.
But to answer your question - I use NeatImage to reduce the noise. I do a handful of night photography using ISO 200 on a Canon 350D at f/8 30seconds shutter speed - the noise is quite visible at 100%. What I do is to run through Neat Image and let it calculate the noise level.
There is another popular one called Noise Ninja that you can use to reduce noise. Both these programmes have a trial period (I think), and they are camera specific - ie for different cameras at different ISOs, they have different settings at reducing the noise. Also, these programmes are pretty simple to use.
Hope that helps. FYI - I don't know what GIMP means. Thanks.

I just tried Neat Image and it crashed but the result looked good for ISO400, maybe I buy it someday from the earnings from myLot :D I hope I find more to post to so I get the money needed...

Well, I think you can increase your megapixel. These days, most (not all) digicam come with the option to choose the quality of the picture produced. Maybe you can do that to see if it helps.

Thanks, but I have a 5MP Cam and I already use Maximum. But you're right, if I would have for example a 10MP Cam I could compact it to 5 or 6MP and then the Noise would be compacted, too. But I think I found another way.

very funny, I expected everything as first response but not something like that.
