Which is more practical, flash or fill light

Flash and fill lights each have their own advantages and applicable scenarios, and their practicality depends on the specific needs of the user. Here is a detailed introduction:

Flash can release strong light in a short period of time, making it suitable for use in low light environments. It can provide high brightness and contrast photos, and is suitable for taking static photos because it can provide instantaneous high-power lighting, achieving the highest level of sharpness in photos without color deviation.
A fill light is used to provide continuous lighting and is suitable for use in natural light conditions or scenes that require additional ambient light. The light it emits is usually soft and uniform, making it suitable for shooting videos and long-term activities because it can provide continuous light sources and consume relatively little power.
Overall, if users need to take static photos or take photos in low light environments, flash may be more practical; If users need to shoot videos or have a continuous need for lighting, fill lights may be more suitable for their needs.
