Question

Terrance is trying to find the correct setting for his photograph, so he uses a light meter. Which type of metering is he using?

Terrance is taking a photograph of a subject in a room with a window. He decides to use his new light meter. First, he performs
metering by aiming the meter at the key light source, a softbox to the subject’s right. Next, he aims the meter toward the window to measure the reflected light. This type of metering is
metering.

Answer 1

Terrance is using incident metering followed by reflected metering with his light meter to measure light for correct photograph exposure, highlighting the importance of responsive materials in the design of light meters.

Step-by-step explanation:

Terrance is utilizing a light meter for photography to measure the intensity of light in his environment, which is a critical step in achieving the correct exposure for his photographs. The first type of metering he is using involves aiming the meter at the key light source, in this case, a softbox to the subject’s right, which is known as incident metering. This measures the light falling onto the subject. Then, he measures the light coming from the window, which is reflected metering. This type of metering is used to measure the brightness of the light that is reflected off the scene and through the lens (through-the-lens, or TTL metering).

Considering the material when designing a light meter is important because the material must be sensitive and responsive to the specific frequencies of light it will measure. For photography, materials that exhibit a photoelectric effect and can respond to varying intensities and frequencies of light are crucial for accurate readings.
