Example Concept: Reflectors work by bouncing existing light onto the subject, which can be particularly useful in outdoor settings where the sun creates strong directional light. By positioning a reflector opposite the light source, you can fill in shadows on the subject's face, creating a more even and flattering light. Reflectors come in various colors (white, silver, gold) to modify the light's quality and warmth, allowing photographers to control the mood and tone of the portrait.
