Focus Peaking explained simply
What is “Focus Peaking”?
A display aid that highlights high-contrast edges which may be in focus, often during manual focusing.
- 01Adjust focus
- 02Edge highlights
- 03Magnify to confirm
How do you use Focus Peaking practically?
A small exercise
Turn peaking on and adjust focus across a textured object. Confirm with a magnified preview and a captured frame.
- Make a starting version and keep it so you can compare fairly.
- Try the change in the exercise. Keep unrelated choices steady where the exercise allows.
- Compare the result at the size your viewer will actually see. Write down what changed and whether it helped.
How does Focus Peaking solve a problem?
It can make manual focusing faster when an ordinary screen makes sharp edges difficult to judge.
What can go wrong?
Peaking is a guide, not proof. Strong edges can show a highlight even when exact focus is imperfect.
How do you turn the idea into a useful solution?
Start with the specific problem in your image or brief, try the exercise, and keep the version that meets that need. If the result is worse, return to the starting version and change one choice at a time.
Quick check: can you explain the three ideas in the diagram?
Adjust focus → Edge highlights → Magnify to confirm. Explain how each relates to the exercise. Then compare the starting version with your result and choose the one that meets your brief.
