So, if you are not a professional photographer, how do you take and save your photos?  Do you use JPG, RAW or both?  My camera will take photos and save them as both JPG and RAW, so sometimes I use this function to take both in order to have the most editing flexibility.

Mine are always done in jpg I dont even know if my camera does RAW, what is RAW? Is it better or any different than a jpg?

I've done only JPG.  I don't think I'd do RAW because of (1) the size of the files,  but more importantly, (2) there's a concern that RAW technology may not be accessible in the future.

While I like the idea of having what amounts to negatives for my digital pictures, I sure wouldn't want to go the route of the VHS video... almost obsolete.

I always take my photos in JPG. My camera does not even have the function of taking RAW pictures. I actually don't know what is a RAW picture though. But I think JPG is better.

I actually take the shots depending on the kind of clarity I want ultimately. I always keep a few data cards with me. Shots which require greater detail, I like to take them in the RAW format. For eg Close ups, portraits (to bring out the finer details of the face). Long shots and shots taken outdoors (for example shots of human activity or traffic) I use JPG. If I have to take several shots of the subject, I always use JPG.

When I upload my pictures into the computer, they are always in the JPG format. I don't really know how RAW's look like. How do you take a RAW picture? Does the canon ixus have that feature?

most in jpeg cos raw files tend to take up more space than those of other formats like JPEG, but of cos you'll be compromising a bit on the quality, but in normal cases that shouldn't matter

usually in jpg the reason being that raw files tend to take up more space than compressed files such as jpg or gif

Always RAW, always. Much more flexibility for editing, and you always have your original files as "negatives" to go back to. JPGs are compressed and every edit and save degrades the quality. I don't like starting off with a compressed file, it means some of the image data has already been scrapped by the camera.
