How to install the diffuser and how to open the diffuser

Diffuser: A translucent plastic plate mounted on the front of the flash that changes the color temperature of the light emitted by the flash.

It is suitable for use when the color temperature of the light source is inconsistent.

For example, if the photographic room is illuminated with multiple incandescent lamps, the color of the whole room will look yellow, and when the flash is not on, the automatic white balance will set the color temperature in the incandescent range to ensure that the color of the person you shoot is closest to the color you see.

But if you use a flash, you can use the automatic gear to try, the **usually background** is insufficient, the face is purple, the reason is that you use multiple light sources when shooting, the color temperature of these light sources is different, no matter how the white balance of the camera is adjusted, the best solution is to unify the color temperature of each light source (at least let them get close) The incandescent lamp in the room can not be changed, the flash can be changed, the flash is an instantaneous light source with a fixed color temperature, if you want to change its color temperature, just add a filter to the lamp head, this is what we call a diffuser, diffuser function:

1. Divergent light, so that the dazzling straight light emitted by the flash is diverged, so that the irradiated object receives light evenly.

2. Change the color temperature of the flash, and install white, blue, and orange diffusers as needed.

The diffuser is also called the flash diffuser cover, which can soften the light from the flash and make it look more natural. Its principle is to convert the stiff flash direct light through the high-temperature resistant translucent plastic into soft diffused light, eliminating the nasty highlight spots on portraits and other shooting objects, and making your ** as beautiful and natural as the one shot in the studio.

In fact, you can make your own diffuser, and there is no need to use any special brand.

The operation of the diffuser opening is as follows:1. Take the diffuser out of the package and lay it flat.

2. Find the steel ring or support frame inside the hood and pull it out from the inside.

3. Stretch the drawn steel ring or support frame to the full length to form a circle or frame.

4. Next, gently insert the stretched steel ring or support frame into the crease of the diffuser, taking care not to damage the fabric or corners of the diffuser.

5. Gradually stretch the entire steel ring or support frame until the cover forms a certain tension according to its own knotted envy structure, and then the entire diffuser can be placed on the abrasive photographic lamp and ready to use.

The diffuser is also called the flash diffuser cover, which can soften the light from the flash and make it look more natural, and it is a device installed on the flash to soften the strong light. Its principle is to convert the stiff flash direct light through the high-temperature resistant translucent plastic into soft diffused light, eliminating the nasty highlight spots on portraits and other shooting objects, and making the scum pie** as beautiful and natural as the one shot in the studio.

A lens hood is a device used in front of the camera lens to block Hungrya's excess light and prevent lens flare. Most of them are made of metal, plastic and other materials. The shape is mostly flower and cylindrical.

The lens hood can effectively prevent the interference light around the lens from entering the lens, and improve the clarity and color reproduction of the imaging. It is mainly used for backlit shooting.

The principle of the diffuser is to change the two light characteristics. First, the larger the area of the light source, the softer the light will be to grip and disassemble; The second is that the greater the angle of diffusion of the light source, the softer the light. Sometimes, of course, if the environment allows (the ceiling is not too high and is white), you can use a jumping light to achieve soft light.

Diffusers are generally divided into direct diffusers, reflective diffusers and diffuse diffusers. Direct diffuser refers to adding a white cloth in front of the flash to increase the area of the light source (this is called a softbox), and this kind of diffuser can be made by yourself; The reflective diffuser generally has the head facing upwards, and uses a 45-degree inclined white cover to reflect the light; A diffuser diffuser uses a protruding white plastic box to diffuse light!
