Ccd camera about flash adjustment?

The color temperature of the flash used by any camera is fixed and cannot be adjusted. When the smart camera is equipped with a smart flash. Only the output of flash power will be controlled according to the lighting conditions at the scene and the shutter speed, aperture value and ISO setting of your camera. To put it bluntly, some scenes need flash, and some scenes need flash to be darker. Instead of finding that the flash will emit cold light to compensate for warm light, it is found that the flash will emit warm light to compensate for cold light. Only the automatic white balance function can make this compensation.

What you said is rare. Generally, the color of the flash is much colder (referring to portrait photography). Yellow is warmer, which proves that your flash is of little effect and the picture is greatly affected by ambient light. You can try to customize the white balance function and set the color temperature of the scene lower (warmer, lower K value), which should be improved.
