Atlas demonstration: the free source photo and the computed Pincushion Distortion. A portrait of a young woman with freckles is framed against a green chain-link fence. The straight lines of the fence wire and the overlaid white grid curve dramatically inward toward her face.Image: Alex Lambley alexscottlambley · CC0 (via Wikimedia Commons), processed for the AtlasView source ↗
Prompt
Apply Pincushion Distortion to create a centrally pinched appearance, bowing straight lines near the perimeter inward toward the middle. Increase the curvature toward the corners while keeping central details relatively stable. Retain natural colors, lighting, and continuous textures without folds or tears. Preserve the original subject and composition.
The image appears [pinched in the center], causing straight lines1near the edges to [curve inward]toward the middle.
Principle
The algorithm shifts pixels inward2toward the center point. Pixels further from the center are [pulled in more strongly].
Try it out
Adjust the distortion strength to see the inward bending increase.
Classification
Calculated image processing result.

02Pincushion Distortion, applied to “City Hall Station BSL (Unsplash)”A low-angle shot captures a historic clock tower flanked by modern office buildings. The vertical architectural lines of the skyscrapers are pulled toward the central spire, creating a distinct hourglass silhouette.Khürt Williams khurtwilliams (photo); processed for the Atlas · CC0 · Wikimedia Commons03Pincushion Distortion, applied to “Man with skyscrapers and river (Unsplash)”A young man wearing orange sunglasses and a blue shirt stands before a modern urban backdrop. The background architecture and the superimposed grid show a significant inward bow towards the center of the frame.chuttersnap chuttersnap (photo); processed for the Atlas · CC0 · Wikimedia Commons04Pincushion Distortion, applied to “Night city traffic (Unsplash)”A night time city scape shows illuminated skyscrapers and winding highways. The buildings on the periphery appear to lean inward as the transformation compresses the scene toward the center point.Vanessa Bumbeers vansbumbeers (photo); processed for the Atlas · CC0 · Wikimedia Commons05Pincushion Distortion, applied to “Walking Through The Desert (Unsplash)”A vast desert landscape features a lone figure standing near a calm body of water beneath a blue sky. The horizon line and the edges of the terrain are warped, curving toward the center of the composition.Diego Jimenez diegojimenez (photo); processed for the Atlas · CC0 · Wikimedia Commons06Pincushion Distortion, applied to “Young man at Palm Beach (Unsplash)”A man in a striped red shirt is positioned in the center of a lush green pathway. The surrounding foliage and the white reference grid are pinched significantly, drawing the eye toward the subject.Mohammad Faruque primitivestudios (photo); processed for the Atlas · CC0 · Wikimedia Commons07Pincushion Distortion, applied to “Forest gateway (Unsplash)”A dense forest path leads toward a traditional Japanese torii gate nestled among the trees. The overlaid grid bends sharply toward the center, illustrating how the scene is pulled inward away from the edges.Thomas Rohlfs taeks (photo); processed for the Atlas · CC0 · Wikimedia Commons08Pincushion Distortion, applied to “Snowy Brooklyn Bridge (Unsplash)”Two figures walk along the symmetrical expanse of a suspension bridge under a pale sky. The vertical cables of the bridge are warped into deep curves that converge toward the central figures.Emanuel Hahn hahnbo (photo); processed for the Atlas · CC0 · Wikimedia Commons09Pincushion Distortion, applied to “Hidden Baby Bird (Unsplash)”A young bird looks upward from its hiding place within a patch of tall green grass. The blades of grass at the periphery curve dramatically toward the bird's head, creating a tunnel-like perspective.Joy Stamp joyfulphotos (photo); processed for the Atlas · CC0 · Wikimedia Commons
