Sorry for entering Very late in this Section. The basic difference b/e RAW and Jpeg i based on the Algorithm which is written and RAW will come close to 2 billion Colors if it's being converted to .tif. And Jpeg algorthim is based on 1 miliion true color to a certain extent. This makes the .cr2 and Jpeg Diffs
Sorry if I am posting in the wrong section but here's a list of tips for ensuring better photos everytime.
Top Ten Techniques For Better Pictures
1. Move close to your subject: Whether it is The Taj Mahal or your little daughter, get close enough so that you see only the 10 techniques for better photographymost important elements in the view finder. Failure to observe this simple guideline accounts for more unsuccessful pictures than any other photo mistake.
2. Correct Exposure: Make sure that your automatic or adjustable camera is set to give a correct exposure. If your pictures are too light(overexposure) or too dark (underexposure), check the camera manual and set accordingly your exposure criteria.
3. Background: Carefully observe both background and foreground in your viewfinder/display screen before you take the picture. Clutter or confusing elements detract from the main subject. Keep your pictures as simple as possible.
4. Flash: You must make flash pictures within flash-to-subject distance range for correct exposure. There are various flash option available in cameras, check before shoot.
5. Hold your camera steady: Shaky hands or pushing the shutter-release button too abruptly may give you fuzzy pictures. Brace the camera with both hands against your forehead and gently press the shutter-release button.
6. Read your camera manual thoroughly: Become thoroughly familiar with your camera, so that you'll be comfortable making adjustments under a wide variety of conditions.
7. Framing: Place your subject slightly off-center. When shown dead-center in a picture, your subject may appear static and rather dull. Experiment to see where different subjects look best.
8. Keep people occupied: Rather than posing people in a starchy, uncomfortable manner, engage them in a natural, absorbing activity to take their eyes off you and the camera. When people are doing something familiar, their bodies and faces will relax.
9. Direction of Light: Watch the direction of light in your scene. Picture taken in the shade or overcast day may be better than direct bright sun light. Direct light and dark shadows are often unattractive.
10. Take plenty of pictures: Every professional knows that the potential for success increase when more pictures are taken. The more you take photos, your probabilities of getting better pictures will increase.

Modern sensors used in DSLR have a very high Dynamic Range, varying from 12EV to nearly 15EV. That coupled with better A-D converters gives us 12/14 bits of colour data for each R,B,G channel. In contrast jpeg data is limited to 8 bits of colour data per channel.
RAW image gives you the full Dynamic Range from the sensor. For 12 bit RAW there are 1024 gradations per colour so on the whole there will be 1K x 1K x 1K = 1 billion shades. For 14 bit RAW there are 8 billion shades. In contrast jpeg has only 256 x 256 x 256 = 16 million shades.
That means that the data available in the shadows can be made visible, as between 4 and 6 bits of data per colour is available but not visible due to the limitation of jpeg or display. What is done is remap of 12/14 bits of data to 8 bits. Some thing similar to what HDR used to do.
Apart from DR there are other advantages of shooting RAW
. You can switch off the scene modes, distortion control, noise reduction and white balance. These can be applied in RAW post processing.
. Switching off the above results in lesser load to the CPU, which translates to faster burst mode shooting (look up on the net, there are plenty of reviews for this).
. The algorithms for the above functions are basic in the camera, while they are more advanced and more comprehensive in the post processing software. So you get a better image than if you shot jpeg.
. You cab play with exposure to a certain extent and in most cases recover bot shadows as well as blown highlights (highlights only upto +1EV in most cases).
. If colour matching is of importance then you can choose your white balance to perfectly match colours only in post processing.
. You can also use colour shade card image to correct colours automatically.
Both Canon and Nikon have post processing software, and at least in case of Nikon it is free, so there is no reason to shoot RAW, especially if you have a computer and the time.
