What is the viewfinder?

[ Pacific Security Network News ]

Do you know what the viewfinder is? Do you know what the viewfinder is for? Do you know the advantages of the viewfinder? For these questions, Xiaobian will answer you here one by one.

What is the viewfinder?

The viewfinder, that is, the portion of the digital video camera that monitors the image through the eyepiece, is the "window" for the photographer to observe the scene to be photographed.

The viewfinder can be easily divided into a black and white viewfinder and a color viewfinder, but it is a black and white viewfinder for professional digital cameras, because the black and white viewfinder is more advantageous for photographers to properly compose the picture. The structure of the digital camera viewfinder is the same as that of its liquid crystal display. Both use TFT liquid crystal, and the difference lies in the size and power consumption of the two.

What is the use of the viewfinder?

The main function of the viewfinder is to compose the picture, which is to determine the range and layout of the picture, and to monitor the important factors such as light, composition and true color in the framing. In addition, some of the viewfinder functions include displaying the parameters of the shooting and predicting the depth of field, etc. A good viewfinder allows us to have a more intuitive understanding of the final effect of the photo, so that we can take a more perfect photo.

What are the advantages of the viewfinder?

The viewfinder can be said to be designed for professional photography. Therefore, its advantage lies in the professional operation. The viewfinder of the digital camera can generally rotate in the vertical direction, and the rotation angle can reach 90 degrees, which is more convenient for the photographer to shoot in the standing position. Moreover, most of the viewfinders can change the distance of the eyepieces, making it easier for photographers who wear glasses with myopia. In addition, the viewfinder has another advantage, that is, power saving. Generally speaking, when the liquid crystal display is turned off, only the viewfinder can be used, at least one quarter of the time can be saved.
