Shutter Speed research

A shutter speed is aperture diaphragum of a lens and it is also the timing of the camera shutter. These both determine the amount of light which enters the camera and how much light exposes on to the film. On the camera the shutter speed scales will be engraved on the shutter speed dial on most camera bodies. These are mainly labeled on the LCD screen as : 1/8000, 1/4000, 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1 or -1, -2 etc. These are very important as they are the main indicators of the timing of the shutter opening and closing during an exposure process. Most camera have a shutter speed dial located on the top panel of the camera body.  When the shutter speed is set to 1/125 it allows the shutter to open and close within one hundred and twenty fifth of a second whereas 1 is a one full second where the shutter is open , allowing the light to be absorbed and exposed onto the film. When a photographer pairs a slow shutter speed with a panning motion of the camera this achieves a motion blur of objects in the frame. This technique is mostly used for images of travel, most photographers use a busy road as the passing cars are useful to photograph as they are moving at a fast speed.  Apply different shutter speeds can have different effects , you can either create a motion blur on the image or freeze frame an object.
