If you tilt the net off of perpendicular, what happens to the light?

• A. The amount of light passing through is reduced
• B. The color temperature shifts
• C. The light becomes brighter
• D. The beam narrows but quantity stays the same

Answer: (A)

When light passes through a net or mask, the amount that gets through depends on the angle at which the light hits the openings. If the net is perpendicular, the openings align best with the light and more light passes. Tilt it off perpendicular, and the projected openings become effectively smaller from the light’s view, so more of the light is blocked by the net fibers. This reduces the transmitted light, even though the light source’s color spectrum hasn’t changed, so color temperature remains the same. It also won’t get brighter; the total light exiting is reduced, not increased. While the beam’s shape can shift with angle, the overall quantity of light coming through decreases.
