A light modifier is a tool used in photography and videography to change the quality, direction, and intensity of light. Common types include softboxes, umbrellas, and reflectors. These modifiers help create different lighting effects, such as softening harsh shadows or directing light to specific areas, enhancing the overall look of the image. Using light modifiers can significantly improve the aesthetic of portraits, product shots, and other visual content. By controlling how light interacts with the subject, photographers can achieve desired moods and highlights, making modifiers essential for both amateur and professional work in the field of photography and videography.
