Choose Digicam Shutter Speed
After you’ve chosen a specific exposure mode, you may then need to make additional changes to either the f-stop or shutter speed. If you have chosen one of the automatic modes that selects all the settings for you, you may not be able to make any changes. If you have selected one of the creative modes, an automatic mode that allows changes, or the manual setting, now is the time to make changes to the f-stop or shutter speed to get the results you want.
One of the common mistakes made by those new to photography is to use one of the creative modes, such as aperture priority mode or shutter priority mode, and simply shoot without considering what the current setting is! Although these modes are automatic— meaning, for example, that the aperture priority mode automatically sets the shutter speed based upon the
aperture setting — you have to first select an appropriate aperture setting! The same thing applies to the shutter priority mode.You set the shutter speed to be what you want and then the camera sets the aperture to get the right exposure. If you don’t choose these settings, you will simply be using the setting that the camera was last set on.
