Shutter Speed

Shutter speed sometimes also referred to as ‘exposure time’ and on other occasions simply called ‘exposure’. Modern DSLRs contain a piece cloth/plastic between the sensor and the lens. This is called the ‘shutter’. When we click to take a picture the shutter (the piece of cloth/plastic I mentioned above) opens and records light for the duration we have set it to stay open. This exposure records the light on camera’s sensor. The shutter then shuts down to end the exposure and saves the picture on to your camera’s memory card.

Shutter speed

Shutter speed is one of the three pillars of photography. Shutter speed, aka exposure time, or sometimes also called just an exposure. All digital single lens reflex cameras (DSLR) have a piece of cloth, between the lens and the camera’s sensor, called ‘shutter’. When you press the ‘shutter button’ to take a picture, it opens the cloth (shutter) for certain period of time to let light in on your camera’s sensor. It will then shut back to finish the exposure and save the picture on your memory card. Depending on your camera you can set your camera’s shutter speed to:

Bulb or sometimes only denoted by letter ‘B’, 30″, 20″, 10″, 5″, 1″, 1/2, 1/5, 1/10, 1/100, 1/250, 1/500, 1/1000, 1/4000, 1/8000 

Shutter speed creates dramatic effects by either freezing action or blurring motion. If the shutter speed is fast, for example 1/500 of a sec, it can completely freeze action.
