Can ttl still be used in flash?

The essence of flash jump is to measure the intensity of ambient light through the pre-flash of flash, and adjust the output power of flash, so as to achieve better exposure effect. TTL (Through The Lens) technology is a kind of lighting measurement technology, which measures the brightness of the scene through the photometric device inside the camera lens, and adjusts the output power of the flash according to the photometric result. Therefore, TTL technology can be used to measure the intensity of ambient light more accurately, so as to better control the output power of the flash and obtain better photo-taking effect.

In flash shooting, TTL technology can better control the output power of the flash, so as to obtain better exposure effect. Using TTL technology to shoot flash photos can better avoid overexposure or underexposure and ensure the brightness and color reproduction of photos. Therefore, we can use TTL technology in flash photography to get better photo effects.

It should be noted that TTL technology requires information transmission between camera and flash, so camera and flash need to support TTL function before they can be used. In addition, different cameras and flashlights may have compatibility problems and need to be selected and set according to specific equipment.
