SHUTTER SPEED

I am using the Panasonic-FZ8.
I am also in my initial stage still what ever I learnt from the book/web , I tested those things and hope helps to every one.

ToDay- Lesson is Stutter Speed.

The shutter is a mechanism that controls the exposure time of an image. This time can be manually set by using the shutter priority shooting mode from your digital camera. The numbers you'll use will look probably like this:

8, 6, 5, 4, 3.2, 2.5, 2, 1.6, 1.3, 1, 0.8, 0.6, 0.5, 0.4, 0.3, 1/4, 1/5, 1/6, 1/8, 1/10, 1/13, 1/15, 1/20, 1/25, 1/30, 1/40, 1/50, 1/60, 1/80, 1/100, 1/125, 1/160, 1/200, 1/250, 1/320, 1/400, 1/500, 1/640, 1/800, 1/1000, 1/1250, 1/1600, 1/2000 sec.

These numbers represent how long the light will be allowed to hit the digital sensor in order to capture the image.

The shutter is the device that controls the exposure time of the photo. The exposure time usually begins at 1/2000 sec. and goes up to 30 sec.

At 1/250 sec. exposure time, the shutter will let in 2 times more light than at 1/500 sec. and 2 times less than at 1/125 sec.

The exposure time determines how a photo will look, if it will be "shaken" or crystal clear.

Below is some example , you can also try this.
There are two picture of moving fan. Its on full speed but due to the difference of stutter speed in one pic you can easily see the wings of the fan and in other there is only a impression of wings.


Shutter Speed=1/2000 sec


Shutter speed= 1.0 sec

Similarly You can see these two (below) also. A short exposure (of 1/2000 sec.) will "freeze" the water droplets in mid air; the detail of every droplet will be clearly visible in the photo. A long exposure time (of 1/25 sec.) will create a special effect where the falling droplets traces unite to create streams of water.


Shutter Speed=1/2000 sec


Shutter speed =1/25 sec
