A camera requires a specific amount of light to produce the perfect exposure. The exact same amount of light every time.
In the daytime, their is an abundance of light available. The camera can make adjustments to reduce this light to the right amount.
In low light situations, there is not enough light available.
The camera must open the lens aperture to its maximum setting (f2.8 on your camera).
Then the camera can also raise the ISO setting to as high as it can go (ISO-250 on your camera).
If their is still not enough light, the camera must lower the shutter speed to collect enough light.
If the camera must select a shutter speed of less than 1/60th of a second, the camera shake icon comes on to warn you.
That icon means the camera is going to select a shutter speed between 1/30th to 1/4th of a second (1/4th is your cameras slowest setting).
If you handhold the camera at those speeds, you will likely get a blurred photo.
You can do several things to prevent camera movement:
1. Use a tripod to support the camera.
2. Set the camera on a solid surface.
If you must handhold the camera you can reduce camera shake by:
1. Use the viewfinder instead of the LCD to frame you shots.
2. While using the viewfinder, lean your shoulder against a wall, post, doorway, or other solid object
I am having fits with my digital camera that I am thinking about trashing it and getting a new one. It takes really nice pics in the daytime outside. But in low light or at night the pics are always blurry no matter what I do. The camera shake icon is always on. but the pics are ok if it is the daytime. I am not sure if there is a setting I can set it to that would eliminate this problem. The flash sometimes helps the blur but then it sometimes gets too much light. The camera is the Fuji FinPix S3100.
