Digital Camera ISO settings and Noise?
I do not know as much about digital as I do about using film. I have repeatedly read that high ISO numbers produce noise. Could someone please either describe or share an example of a photo with noise in it?

It just so happens some friends and I were curious about this very issue, and in particular the much touted high ISO capabilities of the new Nikon D300. The results of my my ad-hoc tests can be seen via the link below. Please be aware that it is not a masterpiece of web design, but it does show some comparisons at full resolution. I hope it is of some help to you.
Cheers, teef_au

Hello, as Proshoot says it is like films the faster it is the grainier it is. For noise read graininess. I kept reading this and the most fuss was made by professional/semi professionals reviewing cameras they wouldn't give house room to. I think the simple answer to these people is the higher the ISO the grainier-get over it! You can get some good effects with this 'finish'. Good luck and enjoy if you get a digital

ISO characteristics are similar to film where high ISO or fast films tended to a grainy appearance.
So a ISO increseases so does the noise.
Software can reduce noise in images.
