Estella, don't confuse the quality of an image to the color temperature of the light source. Light that we perceive as white actually is often shaded to some degree. While noontime light on a sunny day ("daylight") is pretty white, incandescent bulbs tend to be reddish by comparison, and flourescents are all over the map (but usually blue-ish or greenish). Thanks to the workings of your eye/brain combination, though, you don't really notice these differences. The camera (digital or film), however, will. This is why if you take shots in your living room without a flash unit everything comes out looking "warm". Flashes are balanced to reproduce daylight, so that eliminates that issue normally, but I hope you get the idea. Meanwhile, quality settings usualy have to do with the amount of compression you want the camera to perform when it saves the image as a JPEG file. More compression means more images will fit on a memaory card, but also means that you sacrifice some of the image data that may well affect the final picture quality. I hope that helps...you can probably search this site for all kinds of discussions on both of these topics.
