Control exposure and motion
Choose aperture, shutter speed, and ISO based on the visual result rather than leaving every tradeoff to automatic mode.

During the course primer, listen for ideas that change how you approach “Control exposure and motion.” Pause once to capture a useful point, then apply it while producing an exposure comparison grid with settings, predicted effect, actual result, and chosen working ranges.What this lesson is really solving.
Choose aperture, shutter speed, and ISO based on the visual result rather than leaving every tradeoff to automatic mode. This is lesson 2 because later decisions depend on an exposure comparison grid with settings, predicted effect, actual result, and chosen working ranges. Exposure is a triangle of tradeoffs: light, motion, depth, and image quality move together. Use your own numbers, files, environment, and constraints so the result survives outside the course.
Understand the idea before touching the steps.
Exposure is a triangle of tradeoffs: light, motion, depth, and image quality move together.
Follow these steps in order.
Take the action in each step; then use the deliverable below to prove the lesson is finished.
- 1
Photograph one stable subject while changing one variable at a time to see depth, motion, and noise differences.
- 2
Choose shutter speed first when motion rendering matters and aperture first when depth of field matters.
- 3
Raise ISO only as needed to reach the required shutter and aperture in available light.
- 4
Use the meter, histogram, highlights, and test images to protect important detail rather than chasing a centered meter blindly.
See the standard in context.
Ava freezes flying flour at 1/1000 second, opens the lens, and accepts a higher ISO because sharp motion matters more than perfectly clean shadows. The learner saves an exposure comparison grid with settings, predicted effect, actual result, and chosen working ranges and notes the evidence or assumption behind the choice so it can be reviewed and improved later.
Inspect before you move on.
- The finished work visibly includes an exposure comparison grid with settings, predicted effect, actual result, and chosen working ranges.
- You tested the work against this common failure: Using a low ISO at all costs and accepting motion blur or camera shake that destroys the intended subject.
- Another person could verify this mastery standard: For a new scene, you can name the creative priority and choose a defensible starting shutter, aperture, and ISO.

Watch for this
Using a low ISO at all costs and accepting motion blur or camera shake that destroys the intended subject.
Prove it—don’t just recognize it.
For a new scene, you can name the creative priority and choose a defensible starting shutter, aperture, and ISO.
