If the camera has a "shutter priority mode", usually called "S mode", then the shutter speed is controlled directly by the user when the camera is in this mode, by moving a dial or pressing a button (or both).
If the camera has a "manual" mode, usually called "M mode", then the shutter speed and aperture are both controlled directly by the user by moving dials or pressing buttons (or both).
Some cameras have automatic modes which allow the user to control the minimum and maximum shutter speeds that will be selected by the camera when considering all other factors. If the minimum shutter speed is reached, the camera will increase the ISO or aperture size to compensate for under-exposure. If the maximum shutter speed is reached, the camera will decrease the ISO or aperture size to compensate for over-exposure.
All cameras have multiple shutter speeds and depending the mode your camera is (Manual, Auto, etc...) the camera will choose what shutter speed it thinks will be appropriate for the picture. And most cameras will also not tell you the shutter speed you used, while some will.
Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.

For Canon cameras 'IS' refers to "Image Stabilisation". Nikon have the same technology but they call it "VR" - "Vibration Reduction" and other manufacturers have different names for it but they all amount to the same thing. With some SLR camera manufactures the image stabilisation is built into the body of the camera but generally the IS is built into the lens. It reduces the effect of "camera shake" which can make your images blurry at lower shutter speeds.
in manual mode press trash button. then press left or right on the kew pad for shutter speeds. note: functions will high light in RED

Shutter speed can also be refered to as exposure on some cameras.. the lower the # the longer the shutter stays open... Usually slowing shutter speeds is done for effects photos or low light conditions.. It's crucial that the camera remain still when using a slow shutter speed.
In top cameras, from about 30 seconds to about one ten thousandth of second. Less range in cheaper cameras.

1/4000 - 30sec
The DX2 has a wide range of shutter speeds from ISO 100 to 800, with an ISO boost from 1,600 to 3,200. It has 12.4 megapixels for high quality images.
Shutter speeds determine the length of time that the shutter is open, and that the film or sensor receives light. If I wanted to freeze the motion of a speeding car for example, I would need to have the shutter open for a very short period of time. If I wanted to show that the car is moving, I would leave the shutter open for a bit longer. Many different effects can be achieved by changing the shutter speed.
Focal plane shutter with speeds from 30 seconds to 1/4,000 of a second.
Most companies call these shutters "leaf shutters." It's a shutter that's built into the camera lens. It has two advantages and three disadvantages over a focal plane shutter.The advantages are every shutter speed is a flash sync speed, and every lens contains a shutter of its own so if the shutter on your 80mm lens breaks you can mount your 150mm lens and finish the job. The disadvantages are slower shutter speeds than focal plane shutters will give (Hasselblad 500-series cameras go to 1/500 second and Hasselblad H-series go to 1/800; my Nikon F4 goes to 1/8000), having the shutter in the lens means you have to buy a new shutter with every lens and they are NOT cheap; and at the same shutter speed a focal plane shutter will allow more light to pass, so if you have a handheld meter you have to adjust your exposure to accommodate this.

This is something that can happen with any camera and is not specific just to Olympus. To understand the relationship between camera shake when using a camera with or without flash, you first need to understand the basics of shutter speed, camera metering and flash. The shutter speed in how fast your camera closes the shutter when snapping a picture. Fast shutter speeds of 1/160th of a second and higher are usually required for freezing action. Even at 1/160th, you may get some blurry images depending on what is being photographed. Also, a faster shutter speed allows less light in through the lens and slower more light. This speed needs to be adjusted to capture the proper balance of light for the photograph called Exposure. Most people that use a point and shoot camera are using the automatic modes, such as P(Program). In these modes, the camera is using it's internal meter to control how fast the shutter needs to be for a proper exposure. In a low light situation, the shutter will be slow. Since the shutter is open longer, this will cause camera shake due to the small variations and shakes you are making with your hands. It may not be noticeable to you, but it is to your camera's sensor. So why does it go away when using flash? The answer is simple. Flash happens a fractions of a second... much faster than your camera's shutter. This instant light pulse reaches your subject before the ambient light has time to register on your camera's sensor. Since this light information is seen immediately a so briefly, it freezes your subject in place. Even with a longer exposure, the illuminated subject should stay frozen while ambient light fills the rest of the frame. A trick you can try is setting your camera to a manual exposure and set the shutter speed to 2 or 3 seconds. Take a flash photo of someone, but move the camera around after the flash. Your subject should be relatively frozen while the rest of the frame is blurry or shaky.
