Why do you have to "support" in the camera when filming or advertising?

Auxiliary tools for film and television lighting. Made of tin dust removal paper, white cloth, rice pineapple and other materials. The reflector plays the role of auxiliary lighting in appearance (as an auxiliary lamp) and is sometimes used as a main lamp. Different reflective surfaces can produce different soft and hard light. Recently, reflectors have also been widely used indoors.

Commonly used is a silver reflector. Especially when the main light source such as fluorescent lamp and strongpoint is 1 lamp, it is light and effective. If it is used at close range, you can buy white lining paper in stationery store and paste silver paper or aluminum foil on its monotonous surface, which can be divided into silver reflector and white reflector. Try the silver reflector first. If the reflective effect is excessive, use the white reflector.

An important part of a single-lens reflex camera.

The incident light enters the fuselage through the lens, the light is reflected by the mirror and reaches the pentaprism or pentaprism, and the reflected or refracted light reaches the viewfinder again, so that the photographer can observe the shooting range. When the shutter is released, the mirror rises, and all light irradiates the photosensitive material or photosensitive element to complete imaging.

An important function related to it is the pre-elevation angle of the mirror. When the shutter is slow, the focal length is long, and the safety shutter is larger than the real shutter, the mechanical vibration caused by the elevation of the mirror will affect the imaging. Adjusting the height in advance can avoid image blurring caused by machine vibration.

Can be widely used in life.

For example, in the process of taking a selfie, on the backlight side, the light source is reflected on the face in pure white color (flat foam or white cardboard, etc.). ), and the face of the shooting task will be softer and more stereoscopic. You can take photos with and without reflection for comparison.

Only professional photography will be equipped with props such as reflectors, and many white reflective things can play the role of reflectors. If you don't need exquisite works, the basic effect is not much different.
