Lens correction in Photopea¶

Before cropping a photo, you might want to perform lens correction. Especially if a fisheye lens was used, the straight lines in the photo might be deformed. This would emphasize the center of the photo much more than was actually the case in-situ.

In Photopea:

1. Go to menu Filter, Lens Correction....
2. Move the Amount slider until the lines in the photo are straight again.
3. Confirm by clicking OK.
