Camera Shutter
As a result of something known as your camera shutter, the shutter speed exists. Until the camera fires this, in front of the camera sensor simply put a curtain that stays closed. When the camera fires the camera sensor is fully exposed to the light passing through the lens.
After the opening of the shutter stopping the light from hitting the sensor, the shutter closes immediately after the sensor is done collecting the light. As it triggers the shutter to open and close, the button that fires the versatile camera trigger is also called “shutter button,” or “shutter”.
Shutter Speed
Exposing light onto the camera sensor shutter speed is the length of time your camera shutter is open. Essentially, it’s the span for which your camera takes a photo. In how your images will appear this has a few important effects.
For a significant period of time, you end up exposing your sensor when you use a long shutter speed. Motion blur is the first big effect of shutter speed. Along the direction of motion moving subjects in your photo will appear blurred if your shutter speed is long. In advertisements of cars and motorbikes, this effect is used quite often. Hereby intentionally blurring the moving wheels a sense of speed and motion is communicated to the viewer.
In dim environments with a tripod or to photograph the Milky Way or other objects at night, slow shutter speeds are also used. While keeping everything else completely sharp to create a sense of motion on waterfalls and rivers landscape photographers may intentionally use long shutter speeds.
On the other hand, to do just the opposite – freeze motion shutter speed can also be used. Even from fast-moving objects, you can eliminate motion, like cars driving past, birds in flight if you use an especially fast shutter speed.
Each droplet will hang in the air completely sharp if you use a fast shutter speed while taking pictures of water. To our own eyes, this might not even be visible.
By simply controlling the shutter speed all of the above is achieved. In brief, when you photograph moving objects long shutter speeds create an effect of motion, quick shutter speeds freeze action.
Wired triggers
The ability to extend the shooting capabilities of the camera remote for timelapse itself is one thing missing from the current crop of Wi-Fi remote viewfinder apps. None go beyond the camera's own capabilities full control over camera settings is offered by some apps, while basic control is offered by others.
Demonstrating how much more can be done other app-controlled products is available. Via its headphone socket and via its wired remote input the camera is connected to the tablet or smartphone.
For intervalometer and remote triggers, remote inputs are designed. At set intervals, an intervalometer takes a photo, and it has two main uses.
Capturing unpredictable events such as a wildlife or lightning trigger strike is one. In this hundreds of photos are taken at regular intervals and you'll eventually get the shot you want with any luck. Another is creating time lapses, where to form a fast-motion video a series of photos is strung together.
