Light modifiers are tools used in photography and videography to alter the quality, direction, and intensity of light. They can soften harsh light, create shadows, or enhance colors, helping to achieve the desired mood or effect in an image. Common types of light modifiers include softboxes, umbrellas, and reflectors. These modifiers work by diffusing or bouncing light, which can reduce glare and create a more flattering illumination. For instance, a softbox spreads light evenly, while a reflector redirects light to fill in shadows. Using light modifiers effectively can significantly improve the overall quality of visual content.
