What is the effect of tilting a net off perpendicular in relation to how the beam travels?

• A. The amount of light passing through is reduced
• B. The color rendering improves
• C. The exposure increases
• D. The beam becomes more diffuse

Answer: (A)

When the net is tilted away from being perpendicular to the beam, the effective opening the light can pass through gets smaller. The beam sees a reduced projected clear area, so transmitted light decreases roughly with the cosine of the tilt angle. With less light getting through, exposure would drop rather than rise. Tilting doesn’t inherently improve color rendering—color fidelity depends on the light’s spectrum and diffusion characteristics, not the angle of the net. It also doesn’t make the beam more diffuse; diffusion comes from scattering, not this geometric tilt.
