Aperture- The opening of the lens when the shutter release button is hit.  Aperture is how wide the lens opens when the picture is taken and how much light enters the frame. The wider the opening, the more light and smaller the opening, less light.  Measured in f-steps, aperture is referred to as f/2.8, f/4 etc.

Shutter-  the amount of time the lens is open during a picture.  Shutter speed is measured in seconds, mostly fractions of seconds.  If the shutter is too slow, a moving picture will be blury due to the lack of quickness to catch the picture.

The Olympus FE310 has over 17 different shooting modes.  Also it has high iso sensitivity and faster shutter speeds allowing blur free photos.
