Recognize Shutter Speed ​​or Speed ​​Shutter

a.k.a Shutter Speed​​. Shutter is a sort of layer that covers the sensor. At the time we snap the shutter will be open for some time so that sensors can record light coming through the lens. Duration of the shutter opening is known as Shutter Speed ​​Logically the longer the shutter is opened the more incoming light. And conversely the faster the shutter is opened then the less light is recorded.

The unit is second. Units are easier to understand than Aperture unit. To reduce the amount of light entering a half earlier (-1 stop), shutter speed while staying at the 2. And conversely, to add 
The unit is second. Units are easier to understand than Aperture unit. To reduce the amount of light entering a half earlier (-1 stop), shutter speed while staying at the 2. And conversely, to add light to the previous 2x (+1 stop) living in multiply 2. On a Nikon D50 camera, shutter speed values ​​that can be used on the camera are 60, 32, 16, 8, 4, 2, 1s, 1/2, 1/4, 1/8, 1/16, 1/32, 1 / 64, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000. 1/4000. Shutter Speed ​​Range value on the camera type / brand other more or less the same. On a pro camera, the speed can be up to 1/8000s. Fast enough to photograph the bullet that shot!!

Slow Shutter Speed

Technically using a low shutter speed (great value). Commonly used in low light conditions, the shutter open long lebiiih so the camera can gather enough light to produce an image that we want. If we shoot a scene with multiple moving objects, will produce a cool new effects.

Eg traffic photographing at night effect "light path" / lightrail light of the milling mobil2 recorded in the sensor.

Slow speed can also give the impression of dynamic in our pictures. Like the water in the photo below. This photo was taken on a somewhat tricky because where noon is still plenty of light. The trick is that we reduce the light entering the sensor with a pair or several (stack) ND filter (Neutral Density). This filter will reduce the light several times of the original (depending on the level of ND filter) so many light conditions will look like night.

Or more extreem using BULB mode in which the shutter will remain open as long as you press the shutter button. Usually there cuman in DSLR cameras (bought it now hehehe). In a dark night, we can still capture the moments that exist, such as the track record of the stars in the sky (star trail). Photo below was taken with a shutter speed = 16 minutes.

Slow Shutter Speed ​​and Tripod

Tripod is one that is absolutely necessary if we want the photos experimented with slow speed. The reason is because the camera should be supported by other objects during the shutter open. If not, then the resulting image will blur due to camera shake slide. Normal humans would not stand still holding strong for a few seconds without camera shake. Also not rely on the tripod, objects objects that can sustain kmera with sturdy can also be used as a substitute for a tripod.

High Shutter Speed

This technique produces images with a high shutter speed (low value). If this one does not need a tripod. Enough is held manually by us and the resulting image is guaranteed tokcer. This technique is useful for capturing a moment that happens. Just let him go where we want. Typically used for sports, wildlife.

Or by adding our voice sensor can capture the moment when the balloon burst.

Normal Speed

Shutter speed commonly daily used. In photography there is a rule that states that the ideal shutter speed to produce a sharp pictures (no blur) is at least equal to the Focal length of the lens that we use. For example, we want to photograph an object with Focal length 200mm then shutter speed is 1/200sec ideally. For DSLR with a 1.5x crop factor (Nikon), the focal length should be multiplied by 1.5 first .. means a minimum shutter speed is 1/300sec. Setting the shutter speed 1/300sec readily available during the day and not necessarily in the evening .. so careful to look for the conditions and understand the camera settings so that we get the ideal shutter speed. that's the point. in order not to blur photos

But a blurry photo does not mean the image is bad, not sharp and also not always good. it all depends on taste photographer who took the picture.

Linkages with Exposure

As I've previously pillowcase in Learning Understanding Aperture, exposure is the camera's ability to collect the incoming light. This light is like food for the camera .. Too many images produced will be bright, too little will be darkness. In general, we prefer the middle. Shutter Speed ​​is one of the 3 element determinant of exposure. Others are Aperture and ISO / ASA. Aperture and ISO-could also be set in the camera, determining the amount of light that enters the camera.

Suppose we want to capture the moments of a rocker artists who are performing at night. as His name is just rocker like jump up and down, now we want to capture when he again jump. Because the night, light deprivation cameras to record the moment. In my opinion, a minimum speed 1/500sec .. To achieve the speed so we can change the settings of other elements that Aperture 2 and ISO. Aperture, we are setting the value as small as possible (large aperture) and ISO as possible. Pray and be thankful to be able to speed that we want. If not, find another angle that might give you a lot more light .. or replace the camera / lens. Camera / professional lenses with large aperture would normally drain the pocket deeper. Important in the light of the photographer. Can be referred to a photographer is a light hunter hahaha: D
