Control exposure and focus
Want more background?
The idea in everyday life
Choose exposure based on motion, depth of field, noise tolerance, and highlight protection. In manual mode, set the creative constraints first, then balance remaining variables. Choose focus mode and point based on whether the subject is still or moving.
Shutter controls motion, aperture controls depth and light, ISO amplifies the signal, and focus chooses the sharp plane.
One step at a time.
Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.
- 1
Set shutter speed first when motion blur or camera shake is the main risk.
- 2
Choose the aperture, the lens opening, for how much of the scene you want sharp. Also check how the lens performs at that setting.
- 3
Raise ISO only as needed for the shutter and aperture decision, checking noise and highlight headroom.
- 4
Select the correct focus mode and point behavior, then verify critical sharpness at useful magnification.
See how it works.
For still hands, Kai uses 1/250 second to freeze motion, f/2.8 for separation, and raises ISO until the histogram protects highlights. For video at 24 fps, shutter stays near 1/50 while aperture, light, ISO, and neutral-density filtration manage exposure.
Did you cover these?
- Shutter renders motion as intended and focus is on the meaningful plane.
- Critical highlights are not accidentally clipped.
- Settings are tested at full magnification, not trusted from a small preview.
What to finish
A controlled series showing frozen motion, intentional blur, shallow depth, and deep focus.
Watch for this
Using the lowest ISO at the cost of a shutter speed that creates an unusably blurred image.
How can I tell I understand it?
You can choose which technical compromise best protects the creative priority.

Follow the manual-exposure demonstration by predicting what will change before each adjustment; verify motion, depth, and noise rather than chasing a centered meter.Tools, templates, and lesson sources
