What are the commonly used fill light tools for photography?

Commonly used fill light tools for photography:

1, reflector: This is a more economical and practical light supplement tool. It is not only cheap and easy to carry, but also can control the intensity and angle of light by changing the distance and reflection direction. However, when shooting in gloomy weather or dark places, its function is not obvious, and it may even lose its light supplement function.

2. Portable flash: This flash is compact, powered by the 5th battery that can be seen everywhere in the market, and it is very convenient to carry. If it is the original factory, it can also support high-speed synchronization, and the highest synchronization speed can reach 1/8000 seconds. Only with high-speed synchronization, the coverage of the flash will be greatly reduced, and the faster the shutter speed, the smaller the coverage of the flash.

3. Exterior lamp with rechargeable battery: This kind of flashlight is usually powerful, equipped with a large rechargeable battery, and has strong endurance. Its disadvantages are large size, heavy weight and inconvenient to carry, and the shutter synchronization speed is generally limited to 1/200 seconds.

When taking outdoor portraits, the light in the shed can't be called fill light, because there is no light in the shed, so it should be called "light".
