In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.the shutter speed is the unit of measurement which determines how long shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor. Shutter speeds are expressed in seconds or fractions of a second. For example 2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000. Each speed increment halves the amount of light.
Examples:
Slow shutter speed:
Fast shutter speed:
Best image
Worst image
I think this is my best image because water is in focus as it is dropping because I have taken the picture with a fast shutter speed.
I think this is my worst image because nothing is in focus because I have taken the image with a slow shutter speed. I also could have taken the image with a different background to make the image more interesting.
