SHUTTER SPEED

Shutter speed is a photography term that indicates the length of time the shutter is open to allow light exposure to the film or image sensor. Used in conjunction with aperture size (f-stops), shutter speed determines total exposure and can be changed to create different effects. Shutter speed is measured in seconds, typically fractions of seconds. In other meaning, Shutter speed is what you want to change when you want to show movement in your picture or when you want to take an incredibly clear shot, a moment in time, without any blur of movement at all. The slower the shutter speed is, the more movement the camera will capture.

It is adjusted automatically when a camera is being used in automatic mode. However, shutter speed can be adjusted manually on most SLR film and digital cameras. Conditions that typically account for determining shutter speed include lighting and movement. A slower shutter speed is used in low lighting, while a short, or quick, shutter speed is typically used to capture moving objects. To create dramatic effects, such as intentional blurring or other artistic effects, the shutter speed may be adjusted to atypical speeds for the given conditions.

The three main adjustable parts of your camera are ISO, aperture, and shutter speed. Aperture and shutter speed together are what determines exposure because they both affect how much light is taken in while the picture is being taken. The most basic definition of shutter speed is how long the shutter takes to open and close.

Fast Shutter Speed

• There are some rules of thumb for setting shutter speed, such as slower settings in low light and quicker settings for fast-moving subjects, but determining shutter speed for the desired effects is more a matter of trial and error.
• The length of exposure can also be more controlled and much faster with focal-plane camera shutters than with central shutters, allowing for high speed photography. Central shutters are generally more able to synchronize exposure time with the use of flash than focal-plane shutters.

Slow Shutter Speed:

• Conditions that typically account for determining shutter speed include lighting and movement. A slower shutter speed is used in low lighting, while a short, or quick, shutter speed is typically used to capture moving objects.
• Play around with these settings to get creative shots from what could be run-of-the-mill subjects. Most cameras allow for photography techniques such as slower shutter speeds and smaller amounts of light coming in. These small changes can make a big difference.
