Vignetting explained simply
What is “Vignetting”?
The corners of an image becoming darker than the centre, either from optics, obstruction or an editing effect.
- 01Bright centre
- 02Darker corners
- 03Check the cause
How do you use Vignetting practically?
A small exercise
Photograph an evenly lit wall with a wide aperture. Compare the corners before and after a lens-profile correction.
- 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 Vignetting solve a problem?
It can explain uneven brightness or deliberately draw attention towards the middle of a picture.
What can go wrong?
Strong correction can reveal corner noise. Check whether a filter or lens hood is causing an obstruction.
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?
Bright centre → Darker corners → Check the cause. Explain how each relates to the exercise. Then compare the starting version with your result and choose the one that meets your brief.
