How to Reduce the Fisheye Effect in Photos and Videos

Reduce the wide-angle, curved nature of pictures and videos.

  • All cameras

Fisheye. Barrel distortion. Wide-angle...

It's that immersive GoPro 'feel' you get every time you look at your footage--be it a single photo or video clip, we want your camera's wide-angle lens to capture as much of your experience as possible. GoPro footage is known for its crisp image quality, coupled with a slight fisheye effect. We don't want you to worry about if you're getting something in the shot--point your GoPro in the general direction of a subject, and we want whoever's watching to feel like they were right there with you.

That said, there are certain instances where you want to minimize the barrel distortion. So how do you go about doing that? We've got two options for you: 

1. On the Camera
Shoot in a resolution that allows you to record using Linear FOV or (if your resolution/frame rate combination does not offer Linear) reduce the camera's Field of View (FOV) by zooming (or selecting Medium or Narrow on earlier model cameras). The level of barrel distortion increases as you move from the center of an image to the extremities. Shooting in a narrower FOV is akin to cropping the camera's image without the need to use editing software, cutting out the portions of the image that have the highest levels of distortion all by changing the FOV setting on the camera.

It's important to note that not all photo and video resolutions offer all FOV settings. Available settings are Narrow, Linear, Medium, Wide, and Superview.

2. Using GoPro Studio
GoPro Studio has a great, built-in Fisheye Removal Tool (learn more here). It's similar to changing your camera's FOV, but with two key benefits: 
  • It uses software to help straighten your footage out. There will still be slight cropping of your footage, but not to the same degree that you'll see when changing the camera's FOV.
  • You can choose whether or not you want to utilize the tool after you've taken the video or photo. This gives you a bit more freedom in editing; you can shoot using a Wide FOV to make sure you capture as much of the scene as possible, and then determine if you want to keep the wide-angle or straighten things out a bit.
