In the context of lighting accessories employed in film versus theater, a reflector board is more commonly used in film production to manipulate natural light for desired effects, while theater settings rely less on this tool due to controlled and fixed lighting conditions.
The question pertains to which lighting accessories might be used more commonly in film than in theater. Among the options given, a reflector board is more commonly utilized in film production compared to theater. Gobos and lighting boards are widely used in both realms, but the nature of film, which often requires manipulating natural light and shooting in various locations, makes the use of reflector boards more prevalent to achieve the desired lighting effects. In contrast, theater productions are typically fixed in one location with controlled lighting conditions, making the use of a reflector board less common.
