Wireless flash trigger for indoor photography

In indoor photography, a flash trigger is an absolutely indispensable tool. It emits a flash light source to the photography light through the hot shoe of the SLR camera. This part of the flash trigger is divided into active and passive. First, the active receiver needs to be connected to the power supply and connected to the photography lamp, while the passive receiver uses AA batteries. There are some flash triggers on the market that use wired flash triggers and work at high voltage. If not operated properly, the motherboard of the SLR camera will be burned out through the hot shoe, so it is not recommended to use them.
