Teach you to deal with glare in photography

Glare is easy to appear when you shoot at the sun. Although glare is usually unpleasant, sometimes photographers want to highlight the dazzling brilliance of light, and they often deliberately produce glare in their photos. The glare on the top and right is deliberately made by the photographer to highlight the dazzling brilliance of the light.

What is dazzling light?

All lenses will be affected by some non-ideal factors in the process of transmitting images. One kind of aberration is called glare.

Camera lenses are assembled by many individual glass lenses. These individual glass lenses are called lens units. When bright light passes through camera lenses, part of the light will be reflected by the surfaces of these lens units. This internal reflection will create an illusion and appear in the final photo like an image. For example, a small light spot similar to a heptagon that appears near the upper right corner of the picture is glare.

In order to reduce glare, almost all modern lenses are coated with a very thin chemical film on each surface of each unit to reduce the reflectivity of these surfaces. Although coating can reduce glare, it can't completely eliminate glare; This is especially true when the lens is aimed directly at a very bright light source, such as the sun or floodlight. Since we know that the front and back of the camera lens may be coated, we should be extra careful when cleaning both ends of the lens. A rough wipe will remove the coating.

When installing a filter in front of the camera, you should be especially careful to dazzle. Because two additional surfaces are added, they may reflect strong light and produce glare.

Glare seen in the viewfinder of a SLR camera will be recorded on the film. Therefore, we must be alert to any light spots and glare in the viewfinder and avoid the lens facing the sun directly.

How to eliminate glare?

If glare has been found, how to eliminate it? Here are some ways to deal with glare:

Use a hood. If the light is just at the edge of the image, installing a hood on the lens can eliminate this glare (but if the light is just in front, the hood can't do anything).

Adjust the aiming direction of the lens. Find a shooting direction that can eliminate glare. Sometimes, the glare at some points may be eliminated as long as it deviates slightly from the direction of the light source. However, what if the subject does not allow the camera to move or rotate?

Block the light. Block the direction of the light source with your hand (or hat or cardboard) at a certain position in front of the camera. Make sure the obstacles are high enough, otherwise they will appear in the viewfinder.

If these measures still don't work, it seems that we will have to put up with these dazzling lights. However, this annoying guy can sometimes cooperate with our creation and shoot some particularly beautiful pictures.
