Contributions do not have to be cash. They can include wardrobe, makeup, styling, props, location access, materials, tools, equipment, transportation, creative direction, or other resources used to support the shoot.
Selecting a boundary level only indicates what you are open to discussing. It does not confirm that the project will include that direction. All boundaries, wardrobe, usage, and release terms are reviewed before confirmation.
Please describe the concept, tone, boundaries, intended usage, and what you are comfortable with. This does not guarantee acceptance.
