About Lens Distortion Correction

Lens Distortion Correction removes optical distortion from photographs caused by camera lens characteristics. Wide-angle lenses tend to produce barrel distortion where edges bulge outward, while telephoto lenses can cause pincushion distortion where edges are pulled inward. In architectural photography, straight lines appear curved; in real estate photos, room shapes may look different from reality.

This tool applies Brown-Conrady model-based radial distortion correction at the pixel level on Canvas, using bilinear interpolation for smooth results. Negative strength values correct barrel distortion, while positive values correct pincushion distortion.

Zoom adjustment lets you fine-tune framing after correction, and presets allow quick application of common distortion patterns. The gridline overlay helps you verify straight-line preservation, and the Before/After slider provides an intuitive side-by-side visual comparison. Useful for action camera footage (GoPro, etc.), smartphone ultra-wide shots, and archived photos taken with vintage lenses.
