How does file size affect my digital camera's image quality?

Mark Comon (Vice President, Paul's Photo, Torrance, CA) gives expert video advice on: How does my digital camera turn my picture into a file?; How do various types of memory cards differ?; How much memory do I need for my digital camera? and more...

One of the basic settings you need to make on your digital camera is to adjust the number of megapixels and the type of file you make on the camera. Most of your cameras come with the camera set at less than highest quality, so you need to go into the menu on your digital camera and adjust to set the camera to the highest megapixel and to the highest picture quality, or what I call fine JPEG. Some cameras actually call it fine JPEG, some call it high-quality or super-quality, but you want to set on your digital camera in the setup menu first when you get it out of the box, or if you come to Paul's Photo or a camera store like mine, we always do that for our customers to make sure that you're getting the best quality.
