Question 1

What is the inverse square law's practical implication for studio lighting?

Accepted Answer

Doubling the distance from the light to the subject quarters the light intensity

Answer

The inverse square law states that light intensity falls off proportionally to the square of the distance, so doubling the subject-to-light distance reduces the light reaching the subject to one quarter.

Question 2

When using colored gels on background lights in a studio, what is the best practice to prevent the gel color from contaminating the subject?

Accepted Answer

Place a gobo or flag between the background light and the subject

Answer

Placing a gobo or black flag between the gelled background light and the subject physically blocks spill from the colored light, preventing unwanted color contamination on the subject.

Question 3

What is the primary difference between a monolight and a pack-and-head studio strobe system?

Accepted Answer

Monolights have the power supply built into the head, while pack-and-head systems use a separate external power pack

Answer

A monolight integrates the power supply, controls, and flash head into a single self-contained unit, while a pack-and-head system uses a separate power pack connected to one or more flash heads.

Question 4

What is 'painting with light' in a studio context?

Accepted Answer

Using a moving continuous light source during a long exposure to illuminate different parts of the scene

Answer

Painting with light involves using a handheld continuous light source—such as a flashlight or LED panel—and moving it across a subject during a long exposure to selectively illuminate areas.

Question 5

In split lighting for portraits, how is the key light positioned relative to the subject's face?

Accepted Answer

To the side at a 90-degree angle, illuminating exactly half the face

Answer

Split lighting positions the key light 90 degrees to the side of the subject so that exactly half the face is illuminated and the other half falls into shadow, creating a dramatic, high-contrast look.
