FREE Photography Exposure Triangle Mastery Questions and Answers Flashcards

What is the primary visual effect of using f/22 versus f/2.8 in landscape photography?

Answer: Much greater depth of field with everything in focus

f/22 is a very small aperture that produces extensive depth of field, keeping both foreground and distant elements sharp in landscapes.

A photographer's light meter reads a correct exposure at f/5.6, 1/500s, ISO 400. Which alternative setting gives the same exposure?

Answer: f/8, 1/250s, ISO 400

Closing from f/5.6 to f/8 loses one stop of light, and slowing from 1/500s to 1/250s gains one stop back, keeping exposure identical.

Why might a photographer choose ISO 100 over ISO 1600 when both produce acceptable exposure with different aperture/shutter combinations?

Answer: ISO 100 produces less digital noise and greater dynamic range

Lower ISO values produce cleaner images with less digital noise and preserve more highlight and shadow detail through greater dynamic range.

Which scenario best demonstrates why understanding all three exposure triangle elements together is essential?

Answer: Shooting sports indoors under artificial lighting

Indoor sports require balancing fast shutter speed (freeze action), wide aperture (gather light), and high ISO (compensate for dim lighting) simultaneously.

A photographer using Aperture Priority mode selects f/2.0 in a bright scene. What will the camera most likely do automatically?

Answer: Select a very fast shutter speed to prevent overexposure

In Aperture Priority mode, the camera compensates for the wide aperture in bright light by selecting a very fast shutter speed to avoid overexposure.

What is the 'Sunny 16 Rule' and how does it relate to the exposure triangle?

Answer: On a sunny day, use f/16 with shutter speed matching ISO for correct exposure

The Sunny 16 Rule states that on a bright sunny day, setting aperture to f/16 and shutter speed to the reciprocal of ISO (e.g., 1/100s at ISO 100) yields correct exposure.
