File Formats in Digital Cameras - JPEG

The most widely used file format and the one most people are familiar with is JPEG. It was named after the company that developed it 'Joint Photographic Experts Group'. The fascinating thing about the JPEG format is that it can shrink the size of your digital files up to 90 percent. The only disadvantage is that it greatly reduces the quality of the image.

JPEG is great for snapping every day photos just used in the home, on the computer or emailing. It's best to use the best JPEG setting as often as possible unless you are desperate for more space on your memory card.

One interesting thing I recently learned was that every time you open a JPEG file on your computer and re save it again or even send it on through email it reduces the image quality.
