Shutter speed bracketing 
The shutter is a controller of light and motion.

Example of Exposure values-normal exposure

Fuji Provia 100
Normal Exposure - 
1/125 @ F16
 
Known Exposure: 
Sunny 16 Rule 

Example of exposure-one stop over exposure

One Stop over Exposure - 
1/60 @ F16  

Example of exposure-one stop under exposure

One stop under exposure - 
1/250 @ F16

The shutter has the ability to create motion or to freeze it as in the photographs below.

Example of slow shutter speed

Example of fast shutter speed

Slow Shutter Speed
1/30 to 1/8 of a second
Using slower shutter speeds help to 
create a nice soft effect to the water.

Fast Shutter Speed
1/125 to 1/500 of a second.
Using faster type shutter speeds, you 
have the ability to freeze or stop motion.


Below are some common shutter speeds found on most cameras.
1/1000 -1/500 -1/250 -1/125 -1/60 -1/30 -1/15 -1/4 -1/8 -1 second

Just remember, if you only create one image in the camera, that will be your only image.

One known exposure - Sunny Sixteen.

Your exposure is the reciprocal of your film speed.
From about 10 AM in the morning to around 4 PM in the 
afternoon, a front- lit subject can be exposed by using this setting. 
If your film speed is 100 ISO, your shutter speed would
be 1/ 125th of a second and your aperture would be F-16.
If your ISO were 50, your camera setting would be – 1/60th 
of a second and your aperture would be set at F-16.
