- Factual relationship
Aperture affects Exposure
A wider opening increases the light reaching the sensor during the exposure.
Conditions: Scene illumination, shutter time and lens transmission are held fixed.
- Factual relationship
Shutter speed affects Exposure
A longer shutter time collects light for longer.
Conditions: The illumination is continuous and other light controls are unchanged.
- Factual relationship
ISO contrasts with Exposure
ISO changes camera response; light exposure describes what the sensor collects.
This comparison works in both directions.
- Factual relationship
Stops used for Exposure
Stops express light changes as doubling or halving rather than unrelated setting numbers.
- Factual relationship
Metering used for Exposure
Meter readings provide a starting point for exposure choices.
- Factual relationship
Exposure affects Highlight clipping
Increasing captured light can push bright regions beyond the sensor recording limit.
Conditions: Scene brightness and sensor limit are fixed.
- Factual relationship
Exposure affects Image noise
More collected light can improve the signal relative to noise.
Conditions: Compare similar scene areas and rendering; avoid saturation of important highlights.
- Factual relationship
Continuous light affects Exposure
Scene illumination contributes light for the duration of capture.
