Reasons for Shooting in RAW

File size
- If you look at the OOC JPEGs vs the RAW files, you will see the RAW files are much larger (on my A57 I get 16MB RAW files and about 4 MB JPEGs. This means that the RAW file contain much more information from the camera that you can use to process the shot. It means you have the info that the camera has for the shot, but you can also ignore that info and apply any settings that you desire. It means you can apply as much or as little sharping, noise reduction, or colour correction as you wish to achieve the results that you desire.

The OOC JPEG however, is a file which has been processed by the camera and compressed. You dont have all the data from the camera. This means that processing a OOC JPEG becomes more difficult, you have less data to work with as much of the extra data has been either compressed or removed from the file. For minor adjustments this isnt too much of a problem, however, for major adjustments you run in to the issue of posterization (http://en.wikipedia.org/wiki/Posterization)
