The question whether to shoot in JPEG or RAW has been bantered around since the advent of digital photography.
Lets start by looking at what main differences are.
A RAW file captures all the image data recorded by the sensor when an image is taken.
A JPEG file is a compressed file and a lot of data is lost when taking an image.
Most new camera's offer you the choice of shooting in RAW or JPEG or both at the same time.
