Exposure Triangle
The three camera settings that together determine a photograph's exposure: aperture (light opening size), shutter speed (duration of exposure), and ISO (sensor sensitivity to light).
What is Exposure Triangle?
The exposure triangle describes how aperture, shutter speed, and ISO interact: aperture controls depth of field AND light intake; shutter speed controls motion blur AND light duration; ISO controls brightness AND noise level. For product photography, typical settings prioritize: low ISO (100–400) for minimum noise, small aperture (f/8–f/11) for front-to-back sharpness, and shutter speed set to achieve proper exposure (1/100–1/250 with studio lights, slower with natural light). Understanding the exposure triangle allows photographers to achieve consistent, quality exposures across a product catalog.
E-Commerce Relevance
Mastering the exposure triangle is the foundation of consistent product photography — inconsistent exposures across a catalog look unprofessional and signal poor quality to marketplace buyers.
