The digital age of photography has brought with it a huge amount of control in the way an image can be enhanced post process. Shooting RAW means that you will need to edit your photos in a software bitmap graphics editor like Adobe Lightroom or Adobe Photoshop. If you don't, then these RAW images will come out flat and fuzzy. When shooting RAW you will basically be able to process the image yourself, however when shooting in a format like JPEG, the image information is compressed and lost. .JPG is the extension you will most likely see on your image file name and is an acronym for Joint Photographic Experts Group who formulated the process. Because no information is compressed with RAW you're able to produce higher quality images, as well as correct problem images that would be unrecoverable if shot in the JPEG format. I have often come across individuals who pride themselves on relying solely on the camera settings. These are purists who's photos will be few and far between amazing unless its a bright sunny day. This is because they have decided to let the built in function of the camera process the resultant image automatically. Now don't get me wrong, you can take a very good photo in standard .JPG and I would do that if I were on holiday when I take hundreds of photo's and really don't want to process manually myself. However if I shot an event or a wedding as a professional, it would be irresponsible of me not to afford myself the best chance of producing the best result for my client in RAW. By the way, once a RAW image is processed in a bitmap graphics editor, it is usually saved as .JPG but can be saved as .TIFF or .PNG or any format of your choice. Also you can edit a JPG file in a graphics editor, but with limited options.
