high and low comparison of exposure triangle elements.
The exposure triangle—ISO, aperture, and shutter speed—is the foundation of every photo. But what happens when you push these settings to their limits? High ISO boosts brightness but adds noise. Wide apertures create dreamy blur, while narrow ones sharpen everything. Fast shutter speeds freeze motion; slow ones paint with light.
This post breaks down how high and low settings affect your image—and how to balance them for creative control
ISO: Controls your camera’s sensitivity to light.
HIGH ISO:(eg:6400) Brighter image in low light—but more grain/noise.
LOW ISO:(eg:100) Cleaner image, less noise—ideal for bright conditions
APERTURE: The size of the lens opening that lets light in.
LOW/WIDE APERTURE:(e.g., f/2.2): More light, shallow depth of field.
HIGH/Narrow aperture (e.g., f/16): Less light, deep focus
photo specs: shutter speed 1/30 sec. aperture: f/13 ISO:6400
SHUTTER SPEED: How long the sensor is exposed to light.
HIGH/Fast shutter (e.g., 1/3200s): Freezes motion—perfect for action shots
photo specs: shutter speed 1/3200 sec. aperture: f/2.2 ISO:200
LOW/Slow shutter (e.g., 1/50s): Blurs motion—great for light trails or waterfalls
photo specs: shutter speed 1/50 sec. aperture: f/14 ISO:200
