RAW vs. JPG in one image

Most of our DSLR's have RAW capabilities as well as JPG.  This is one example of why using the RAW settings may be a great idea.  You may have already seen this post if you frequent Reddit.com. Here is a comparison shot of what happens in RAW vs. JPG. RAW keeps the information of every pixel on the sensor of the camera.  In JPG however, whatever is too light or too dark (highlights / low lights) will be approximated as pure white or pure black.  This means much detail is left out of the picture.  This can become hard when it comes to editing.
