Peterson equates ISO to a "worker bee" analogy. If you have a low ISO (like 100), you have fewer bees gathering light, requiring a wider aperture or slower shutter speed. If you raise the ISO (like 3200), you enlist thousands of bees to gather light quickly, allowing for faster shutter speeds in low-light environments, though at the expense of introducing digital noise or grain. Mastering "Seeing" and Composition
Peterson argues that while many settings might be technically correct, only one or two are "creatively correct" for the story you want to tell.
Bryan Peterson's teaching philosophy focuses on a single core mission: . Peterson advocates for a "get it right in the camera" approach. He encourages photographers to spend less time clicking a computer mouse in post-processing and more time perfecting their settings in the field. 1. Mastering the Exposure Triangle

A small f-number (like f/2.8) represents a wide-open lens aperture, letting in a lot of light. A large f-number (like f/22) represents a tiny lens opening, letting in very little light.
