SUMMARY
In photography, a 'stop' is a fundamental unit representing a doubling or halving of light. This concept provides a universal language to understand and adjust exposure across aperture, shutter speed, and ISO. By using stops, photographers can intuitively compensate for changes in one setting by adjusting another, maintaining the same overall exposure. Understanding stops is crucial for mastering the exposure triangle and achieving desired photographic results.
TAKEAWAYS
A 'stop' in photography signifies a doubling or halving of light intensity.
Stops translate aperture, shutter speed, and ISO into a common, understandable scale.
Adjusting settings by an equal number of stops in opposite directions maintains exposure.
This universal measurement is key to understanding and manipulating the exposure triangle.
