Picture compression qualiti in digital cameras by huitzilopochtli2006-06-17 12:09:47
  Text probably isn't the best thing to test on. by Scirocco 2006-06-17 13:58:07
Try taking pictures of something a bit more colourful, like church windows or a sunset.

Depending on what you are going to do with your pictures it might not matter much to you. For example, if you will shrink all your pictures before using them, it might not be much of a noticeable difference, but if you intend to print them large you may have surviving JPEG artefacts on the printed version.

The RAW versions are larger because they save a lot of extra information normally tossed. I'm guessing the 17.8MB one was a RAW. Cameras normally do some white balancing after a picture is taken, but not if it's a RAW image, letting you adjust them yourself (using the extra information) in something like Photoshop. The pictures are probably stores using lossless compression as well to ensure top quality.

Find the quality setting that fits your needs and use that one.
