Correcting Fisheye Distortion

Fisheye lenses create a distinctive wide-angle effect with noticeable barrel distortion — straight lines appear curved outward, especially near the image edges. While this effect can be creative, many photographers prefer corrected images with straight lines, particularly for architectural and real estate photography.

Our fisheye correction tool straightens curved lines by applying an inverse distortion transformation. The adjustable correction strength lets you control how much of the fisheye effect is removed. Full correction produces standard perspective, while partial correction retains some wide-angle character.

  • Architectural photos benefit most from fisheye correction — straight lines matter
  • Full correction loses the wide field of view — use partial correction often
  • Crop the corrected image to remove distorted edges
  • For artistic shots, keep the fisheye effect — for documentation, correct it
