There is a feature that helps you to take a picture, the LCD screen on the back of the camera as a viewfinder so you can see the composition and shoot photos while viewing the LCD. Live View is defined as a facility where a user can perform camera shooting easier .this feature seems not very attractive, but with this feature you can see the view on the LCD screen, you can directly set the white balance and see the results of the current settings at once. This feature allows us to adjust the white balance. If you’ve tried it, you will definitely continue to use it while shooting.
In addition, the live view is also very useful when you are photographing object such as scenery, food, portrait, etc. When you want to take pictures of objects (eg food), you do not have to be bothered by peeking at the viewfinder. Just look at the LCD. So your camera is placed on a tripod and you just adjust the set meals that look good on camera. If you do not use live view, believe me, you will feel more tired of having to commute regulate food set then saw in the viewfinder. So … we just make it easier right..?
There are two ways to implement system of Live View on a DSLR. The first way is by a single sensor, and the second way is with double sensor. Ideally, Live View on a DSLR is run with the help of additional sensors (dual sensor), so the task of the main sensor for taking pictures are not burdened with the additional task to display the Live View display. But the problem, Live View with multiple sensors is more complicated to be setted than the single sensorof Live View system. Eventually almost all DSLR brands competing in the market applying a single sensor Live View system, which is using one main sensor which also work to take pictures
