The camera flash is mostly used for instant lighting in low-light situations, and it is also used in brightly-lit situations to partially fill light in the subject.
It can emit strong light in a short period of time, and it is a photographic accessory for photosensitivity. It is mostly used for instantaneous lighting in low-light situations, and also used in brightly-lit situations to partially fill light in the subject. Small size, safe to use, easy to carry and stable performance.
After the flash is fully charged, the flash sync contact on the camera turns on the flash circuit. During the flash firing period, the light emitted from the flash illuminates the subject, reflects off the subject and enters the camera (for exposure) and the flash metering element. This photometric element quickly converts the light energy into an electric signal and inputs it to the integrating circuit, and then the integrating circuit outputs an electric signal proportional to the amount of flash light; when the amount of flash light reaches the requirement of appropriate exposure, the integral circuit’s The output of the electrical signal causes the control circuit to trigger the flash stop circuit, thereby extinguishing the flashlight.
