How to avoid lens glare?

Specular glare backlight photography shows that flare, light and even fog are a problem. Although it should be used to do some lighting effects, it is always said that mirror glare affects the quality of photos.

Use the aperture to shoot the lighting effect with glare. Backlight photo. Now that the photos are atomized, the clarity of the photos is reduced. Where's the glare? Speaking of the optical structure of the mirror, the lens group has two mirrors and ten mirrors, and the surface reflection of the lens is about 5%. The more incident light enters the mirror, the more reflection diffusion number, and the more complicated the mirror, which affects the imaging quality. In particular, high-intensity light sources enter the mirrors, so that the mirrors interfere with each other. Glare is easy to form unless you want to create a glare effect. It is highly recommended that 3 prevent mirror glare and let Glare Master 1. Use high-quality coated mirrors. Nowadays, all lenses are made of resin or glass, which are influenced by their own physical elements. 100% of the light enters the camera, and the lens reflects to produce glare. The antireflection film technology is used to improve the light transmittance of the lens and reduce the reflection of more light by the lens.

At present, more than a dozen lenses of zoom lens should be coated with antireflection films with the same characteristics according to the absorption degree of the same light color, so as to effectively improve the transmittance and balance the colors, which depends on the reflective colors of the lenses.

Glare can be completely eliminated by coating, and the selected high-quality coated mirror can reduce glare to a greater extent. When cleaning the mirror, we must pay attention to the coating, destroy the fog and blur the photo exposure. I like to try a style. 2. Using the hood, the optical system of the mirror is widely used to prevent the glare of the mirror. See cylindrical petal-shaped materials: metal, plastic, rubber. Choose a hood that matches the mirror.

After heavy extinction treatment, the reflectivity of the inner wall of high-quality range hood is only about 10%. The use of the hood is only used to suppress the glare of the picture, prevent stray light from entering the mirror, prevent rain and snow from splashing, and protect the camera mirror from accidental collision.

When the light source is too close to the hood, glare will still appear. Cover the side of the light source with your hand or hat to unfold the hood.

3, adjust the angle, since we know the source of glare, we should try to avoid adjusting the mirror or light source, prevent the light source mirror or viewfinder from being too close to the mirror to observe the glare change until we are satisfied, and then press the shutter to adjust the appropriate angle. Glare reflection plays a decorative role, and glare should be used as a style to express my intention to shoot.
