Shutter Speed

In a dictionary, there are two types of shutters. The shutter that is a hinged blind for a window or a shutter that is a mechanism that opens and closes to control the time of a photographic  exposure. As you can guess, we are interested in the shutter for a camera. A shutter controls the length of time light is let in to the sensor. Shutter speed is the measurement of the length of time the shutter is open. The longer the shutter speed, the more light that is recorded and the brighter the image. The shorter the shutter speed, the less light that is let in and the darker the image. A short shutter speed captures motion while a longer shutter speed blurs it. Many will say, “the  faster the shutter speed, the better.” However, a slower shutter speed allows you to add some cool effects. Try experimenting with longer shutter speeds. Maybe just blur the movement of a couple objects by setting your camera on a tripod and using a long shutter speed. Or, blur the whole image by moving your camera. If you don't want a moving object in your image, try to get a slow shutter speed in order to make that object invisible. If you  want a long shutter speed in broad daylight, this can be accomplished by using a filter. For this, you will need a Neutral Density Filter.
