You can reduce fisheye distortion on a GoPro in post by applying lens correction, using the camera’s own correction setting when available, and cropping slightly. The trade-off is that straightening the image also reduces the field of view, so you lose some of the wide look.
Why the Distortion Appears
Action cameras use a very wide lens that bends straight lines near the edges of the frame. That bend gives the familiar rounded look, and it is strongest in the widest field of view settings. Fixing it means mapping the image back to a flatter shape, which stretches the corners and trims part of the picture.
Reduce It at the Source First
- Choose a narrower field of view setting, if your model offers one, before you record.
- Use the camera’s built-in lens correction option when available, as it can apply a similar adjustment automatically. Check your manual for the exact menu name.
- Keep the horizon level and the subject toward the center, where distortion is lower.
- Avoid placing straight lines, such as buildings, near the frame edges.
Fixing Photos in Post
- Open the image in an editor with lens correction, such as Lightroom or similar software.
- Look for a profile for your camera model and turn it on. If none exists, use the manual Distortion slider.
- Move the slider until horizons and vertical lines look straight; avoid over-correcting, which creates a pinched look.
- Use Upright, Transform or guided perspective tools to level lines if needed.
- Crop to remove curved empty corners that appear after correction.
Fixing Video in Post
- Import the clip into your video editor.
- Apply a lens distortion or lens correction effect and use a profile for the camera if one is available.
- Adjust the amount while watching the edges of the frame.
- Scale the clip up a little, typically a few percent, to remove blank edges.
- Check stabilized clips carefully, since stabilization crops further.
Options Compared
| Method | Benefit | Trade-off |
|---|---|---|
| Narrower field of view | Less distortion from the outset | Less of the scene captured |
| In-camera correction | Fast and automatic | Less control, some cropping |
| Post-production profile | Precise and adjustable | Requires editing time |
| Manual slider | Works without a profile | Easy to overdo |
FAQ
Can I remove fisheye completely?
Not entirely, since the wide field of view is part of the optics. You can make lines look much straighter, but extreme edges will always show some stretching.
Should I correct every clip?
No. In action footage the fisheye look is often part of the style and adds a sense of speed. Correct only when straight lines or architecture look distracting.
The Short Version
Shoot at a narrower field of view when you can, then use a lens profile or distortion slider in post and crop the edges. Correct gently so the result looks natural.
