Techniques and Process 1A – Evaluation of Shutter Speed

(Research in Outcome 1, Page 2,3,5)

From my research sources i now know that…

Shutter Speed has developed drastically over the years. When photography was first invented exposure times of days and hours were required where as now, we have exposure times of minutes and seconds.
Shutter speed controls the duration of the exposure/light. Slower the shutter speed more light is let in.  They are measured similarity to apertures in whole stops. However shutter speeds use time…
1/15th, 1/30th, 1/60th, 1/125th, 1/150th, 1/100th, 1/1000th, 1/2000th
Shutter speed is used for numerous things. Firstly is works along side the apertures in order to create a correct exposure of an image so that it is not over or under exposed. However it has other uses. It if often used to freeze or blur motion and also stop camera shake. Faster the shutter speed shorter the exposure time.
High shutters are used to free motion and capture sharper images. These speeds would usually consist of 1/125th or 1/200th. These speeds also help with camera shake, as they are quick you do not have to worry as much if you are unsteady, just keep your body tense and your image should be in focus. However slow shutters are used to create effects. However these shutter speeds consist of 1 second exposure to 1/15th. This will only work if the camera is kept still, the slightest movement can blur an image, for slower shutter speeds it is always best to use a tripod to stop camera shake.
Different lenses require different shutter speeds however. This Is because depending on the lens you are using a telephoto lens or a zoom lens the exposure is completely different therefore slightest amount of movement may affect your image. So each lens length has minimal hand held shutter speeds. These are not exact but just a rough outline.
There are two main types of shutters. Leaf Shutters and Focal-plane Shutters. The leaf shutter is a number of metal blades which form a lightproof disc when the shutter is closed. It is built in to the camera lens and when the shutter button is pressed the blades rotate to form an opening and then they swing shut. A Focal-plane shutter however is built in to the camera. It is two blinds which travel across the film. There are two blinds. The primary blind which contains a rectangular opening  which is slightly larger than the picture frame travels first. Then the second blind starts moving a little bit after which makes the two blinds form a slit that moves the film across. When a short exposure is set a narrower slit is formed.
