Ok, I'm a newbie to digital cameras. I'm just a novice, and will probably always be a novice. I bought a Kodak CX7330, and like it so far. But I have some general questions. 1. What determines the file size in mega-bytes? For example, all my pictures are 2032x1524 pixels, but the file sizes vary. Why? 2. If a camera is set at a lower mega-pixel setting, will the shutter speed be faster than if the same camera was set at a higher mega-pixel setting? If so, then wouldn't it be generally best to have the camera set at the lower mega-pixel setting unless you intend on enlarging the pictures for some reason? 3. How many pixels can the typical computer moniter display? If my camera is giving me 3096768 at the highest quality setting, but if my monitor only displays less than that, shouldn't I turn the quality setting on my camera down to match my monitor? (Again, unless I'm going to enlarge the pictures for some reason).
