Shadowing
As a shading device , flag or outdated Negro is called in studios for a picture shields for blocking light. In the theater area, they serve to maintain the visual unity of a backdrop .
Shadowing in photo technology
In studio photography as well as in film and television , shading or flag is the common name for any dark screen that is positioned between a subject and the surrounding light sources in order to control the incidence of light on the subject or local reflections on the subject surface. Interfering external light incidence on the lens can also be prevented by such shading. In principle, any material that is opaque, non-reflective, preferably light and can be brought into the required shape is suitable for use as a shade. Usually black cardboard or foam boards are used, for larger areas also black strips of fabric, for small areas (also directly on the lamp or flash unit) foils made of black matt anodized aluminum foil .
In particular, the control of reflections on reflective motif surfaces (for example car paint) often requires great precision when using shading, which must be individually tailored to the respective motif and precisely positioned.
The counterpart to the shadow or flag can be seen as the brightener , a bright surface that reflects the exposure light onto otherwise insufficiently illuminated areas of the subject.
"Negroes" on the theater stage
Similar to the area of photo studios, small black fabric walls stretched on wooden frames that can be set up are or have been called “negroes” on theater stages , which serve to prevent the audience from looking into the back or side stage when leaving the backdrop. In this way, the backdrop is optically preserved as a unity. In contrast to the studio area, light-colored blind walls are or were considered to be “negroes”.
