Lock one parameter and generate equivalent exposure settings. Choose full-stop or third-stop rounding to match your camera.
Each stop equals a doubling/halving of light. Equivalent settings shift one parameter by N stops and compensate with the other unlocked parameter.
| Shift | Aperture | Shutter | ISO |

What is an equivalent exposure? A different combination of aperture, shutter, and ISO that yields the same brightness.
Why are values rounded? Cameras use discrete steps, so we map to common settings.
