How to avoid specular reflection in product shooting

The methods to avoid specular reflection in product shooting are as follows:

1, adjust the light source; The light source is placed outside the angle system, the light source is placed outside the angle system, the light source is placed outside the angle system, and the light always reflects from the reflecting surface at the same angle as the incident angle, so that the angle system of the camera and the light source can be easily determined.

2. Add a polarizer in front of the lens. When parallel incident light hits this reflecting surface, it will still be reflected in one direction in parallel to eliminate the reflection.

3. Pay attention to the angle system; There must be a telephoto lens, followed by a macro lens. The telephoto can compress the space, and the product will be larger than the wide angle, because the wide angle amplification needs screenshots, which will lose pixels; It is easier to obtain a small angle system by using telephoto, and the requirement for the position of light source is weakened.

4, the use of polarized lenses, it should be noted that the aperture size needs to match the lens.

5. Adjust the shooting angle. If there is no soft box for indoor photography, try to find a place with shadows and not very dark light. For example, shooting in the corner of the balcony at home at noon or shooting outdoors on cloudy days can avoid specular reflection.

Precautions to avoid specular reflection:

Specular reflection follows the law of light reflection;

The essence of specular reflection imaging is upright and equal, and the virtual image is located on the opposite side of the object;

Specular reflection means that when the incident light is parallel light, it is reflected on a smooth mirror and emitted as parallel light;

Specular reflection and diffuse reflection have the same reflection angle and incident angle. The only difference is that the mirror reflection surface is relatively flat, so the light beam is relatively uniform and the reflection direction is relatively consistent. The non-uniform reflecting surface of diffuse reflection leads to the disordered beam of reflected light. Mirror reflection can be avoided by adjusting the shooting angle.
