RAW vs JPEG

Most modern cameras allow you to shoot in either Raw or JPEG. This site describes in detail the difference between RAW images and JPEGS. Check it out HERE. It is recommended that JPEG format is used for web pictures. RAW format is recommended for professional shooting and higher quality details. RAW format requires post-production editing while JPEG requires hardly nothing.
