I have read many reviews and I keep seeing the description relating to "noise"...at first I thought it meant the noise of the camera operating, then I thought it meant the noise level when recording video, and now I am getting the impression that noise means the grainyness of a photo when enlarged?

Can someone help me with this?

thank you!

A picture is worth a thousand words. Check out this glossary:

It has very nice example pictures that show you exactly what it is.

Thank you so much for the info!

I never knew that buying a digicam could be sooo confusing and full of so many terms to know! Yikes!

But, I am still going to buy one!

Yes, I agree there is a lot to learn when researching digital cameras, and then once you've got one you've gotta learn how to use it and get good pictures. But its nice to have a good, active brain. Keeps ya young.

If you ever shot film, then you actually had to deal with exactly the same thing, called Film Grain. It works exactly the same way... the higher the ISO film the more grain you'll see.
