Understanding Shutter Speed

What is shutter speed? Well...

Shutter speed is the amount of time the shutter is open while taking a photo. When shutter speed is measured, it is measured in seconds. If you take a photo that is more than 1/60th of a second long, then you should use a tripod or some sort of stabilizer like a table or a flat surface. The longer you have the shutter speed open, the more light is let in to the photo. Also when on a faster shutter speed, it captures the moment faster. When on a slower shutter speed, the picture becomes blurry because it does not capture movement easily. 

This photo was taken with a fast shutter speed because the movement is captured very well. 

 This photo was taken with a slow shutter speed because the movement is blurry and the object is not on focus. 

The shutter speed is a very important part in the exposure triangle. The exposure triangle contains of 3 items, aperture, shutter speed, and ISO. If you change one thing, then everything else changes also.  If you change the shutter speed, but don't change your the aperture or ISO, then there won't be the right amount of light coming in through the camera. If there is not enough light/ too much light coming through the camera, then the picture will not turn out the way you want. Everything works together to make the perfect photo.
