Exposure Triangle
Visualise how aperture, shutter speed, and ISO work together. Adjust one setting and see equivalent combinations that produce the same exposure.

Exposure contribution
How each setting affects overall brightness
Mid-range — good all-round sharpness
Fast — stops most movement
Medium — slight grain, versatile
Equivalent exposures
Same brightness, different trade-offs
Aperture
Wide apertures (f/1.4–2.8) let in more light and create shallow depth of field. Narrow apertures (f/11–22) let in less light but keep more in focus.
Shutter Speed
Fast speeds (1/500+) freeze motion. Slow speeds (1/30 and below) can cause motion blur or camera shake without a tripod.
ISO
Low ISO (100–200) gives the finest grain. Higher ISO (800+) allows shooting in lower light but increases visible grain.
Understanding the exposure triangle
The exposure triangle represents the three settings that control how much light reaches your film or sensor. Each setting affects exposure by one stop when doubled or halved.
One stop = doubling or halving the light. Going from f/4 to f/5.6 is one stop less light. Going from 1/125s to 1/60s is one stop more light. Going from ISO 200 to ISO 400 is one stop more sensitivity.
When you change one setting, you can compensate with another to maintain the same exposure. This lets you make creative choices: shallow depth of field, frozen motion, or minimal grain — pick your priority.
