Is it best to use natural light instead of flash when taking pictures?

Natural light can shoot some special environmental atmosphere, which is suitable for artistic photography. However, if the light ratio is too strong, it is easy to appear dead white or dead black areas, so it is usually necessary to use a reflector to make up the light properly. The built-in flash of a small digital camera flashes directly, and the light is very flat, so it is easy to make people's faces lose their three-dimensional sense and have shadows. SLR camera external flash, 45-degree diffuse reflection, can increase the three-dimensional sense and remove shadows. Nice complexion, too. If you are recording meetings or taking photos of leaders participating in some activities, it is better to add an external flash. Many people don't like dark photos.
