Lens distortion is an optical defect that many photography and video users fear. It manifests when light does not travel in a straight line to the sensor, generating distortions at the edges of the frame. Although it is an inevitable physical phenomenon under certain conditions, understanding it helps to correct it. It is not a manufacturer's error, but rather a characteristic of optics.
How to correct distortion in post-production 🛠️
Digital correction has become standard in programs like Lightroom or DaVinci Resolve. These tools apply lens profiles that adjust the geometry of the image. The process maps pixels to compensate for curvature, but it can reduce sharpness at the edges. Some manufacturers integrate automatic correction into the camera body, which streamlines the workflow. However, the quality of the result depends on the accuracy of the profile.
The ironic side of lens distortion 😏
It is curious that we spend fortunes on lenses with high-purity glass only to later apply an Instagram filter that simulates distortion. So you can buy a 2000 euro lens, shoot perfectly straight, and then add a vintage preset that warps everything. In the end, the optical error has become an aesthetic effect. Coherence, like light, sometimes deviates.
