What is the function of the honeycomb board in the attachment of film and television flash?

The honeycomb panel is used as a light beam to make the light directional and prevent it from running to other places, so it can be used to prevent glare.

The honeycomb panel in the video flash attachment is black, and the qualified honeycomb panel will not affect the color temperature.

Beehives enhance the light. The soft box is equipped with a beehive. Control the distance, the light is soft and will not soften the light. Most of them will harden.

Almost all modifiers, including soft boxes, umbrellas, reflective umbrellas, reflectors, etc. , will lose some light, so the light will definitely weaken, not soft light. Light bright spots and dark spots will not affect the hardness.

Extended data

There is also a honeycomb cover used with honeycomb board in the video flash attachment.

The honeycomb cover is actually a black square cover installed in front of a flashlight or lamp, and its external image is a neat beehive or grid, hence its name.

When the flash light source passes through the grid of the honeycomb panel, it will become directional light, so that the irradiation range of the flash line is limited in an area, forming the effect of gradually losing light from the center to the periphery.

The smaller and denser the mesh of the honeycomb cover, the more obvious the light loss effect and the more concentrated the light irradiation range. The light emitted through the honeycomb cover often has a rich and obvious gradual change because of its good directivity, bright and dark.

There are more than one device (such as beam tube) to limit the irradiation range of flash lamp, but honeycomb cover can find the best balance between controlling light, providing pleasant effect and gradual attenuation of light.
