A mobile phone fill light is an accessory designed to enhance photography and videography by providing supplementary lighting. It typically attaches to smartphones and offers various brightness levels to illuminate subjects in low-light environments or to enhance the overall lighting quality of images and videos [4]. These fill lights often come with features like adjustable brightness levels, rechargeable batteries, clip-on designs, and different color temperatures to suit diverse shooting conditions. The primary purpose is to improve the quality of photos and videos taken with a smartphone, especially in settings with insufficient lighting.
Different models might offer additional functionalities like built-in lenses, such as macro lenses, to capture close-up details or other specialized effects [2]. Furthermore, some fill lights are compatible with accessories like phone clamps, allowing users to attach them to stabilizers or gimbals for smoother shooting experiences [6].
These fill lights cater to users seeking better illumination for their smartphone photography and videography, providing a portable and versatile lighting solution.
