Blackwrap is an thick foil used to shape and control light. It is made by various manufacturers and comes in different sizes. While it is most commonly anodized black to prevent reflections, there are black and white combinations available. As you can see below, a popular brand of blackwrap is Cinefoil made by Rosco.
Blackwrap is chosen instead of fabric or paper because it’s metal and less likely to combust when placed in front of a hot light source.
Some other uses for Blackwrap:
- Altering the shape of your light source.
- Blocking light from where you don’t want it to go.
- Blocking daylight from entering windows.
- Used as a makeshift gobo (go between) to cast a shadow in a certain shape onto your background. With a sharp knife you can cut a patten that you want projected.
- Used as a lens hood to prevent flare from entering your camera lens.
Due to it’s durability, and since it can be a bit pricey, it is often reused over and over again. Anybody who has been in the business long enough will have a piece of black wrap that has the texture of a raisin!
