Prompt
Apply Barrel Lens Warp, introducing moderate outward bowing of straight lines toward the frame edges. Gently expand central forms and compress peripheral spacing, producing smooth convex lens geometry rather than waves or a spiral. Retain original colors, sharpness, and natural lighting. Keep the original subject and composition.
02Sendlinger Tor - Fisheye LensA fisheye photograph of an archway. The brick structures at the edges exhibit significant outward curvature, illustrating the non-linear scaling of radial coordinates common in barrel distortion effects.lester289 · CC BY-SA 4.0 · Wikimedia Commons03Fisheye lenses - Canon 8-15 "Sheikh Lotfollah Mosque" لنز فیش آی (چشم ماهی) 8-20 کانن، مسجد شیخ لطف الله اصفهانA circular fisheye view of a mosque interior. The geometry is mapped onto a sphere, resulting in extreme outward bowing of architectural lines as a manifestation of extreme barrel warp.Mostafameraji · CC BY-SA 4.0 · Wikimedia Commons04Fisheye lenses - Canon 8-15 "Sheikh Lotfollah Mosque" لنز فیش آی (چشم ماهی) 8-17 کانن، مسجد شیخ لطف الله اصفهانInterior shot with a fisheye lens. Straight walls and floor tiles appear curved due to the lens's radial mapping, providing a clear visual example of barrel lens warp.Mostafameraji · CC BY-SA 4.0 · Wikimedia Commons05Fisheye lenses - Canon 8-15 "Sheikh Lotfollah Mosque" لنز فیش آی (چشم ماهی) 8-16 کانن، مسجد شیخ لطف الله اصفهانA circular fisheye exterior view. The long, straight building facade across the center is heavily warped into a curve, characteristic of high-magnitude positive radial distortion.Mostafameraji · CC BY-SA 4.0 · Wikimedia Commons06Fisheye lenses - Canon 8-15 "Sheikh Lotfollah Mosque" لنز فیش آی (چشم ماهی) 8-18 کانن، مسجد شیخ لطف الله اصفهانA fisheye view of a tiled corridor. The vertical walls curve sharply outwards towards the center of the frame, showing how barrel warp alters the perception of rectilinear spaces.Mostafameraji · CC BY-SA 4.0 · Wikimedia Commons07Fisheye lenses - Canon 8-15 "Sheikh Lotfollah Mosque" لنز فیش آی (چشم ماهی) 8-15 کانن، مسجد شیخ لطف الله اصفهانA circular fisheye photograph of a courtyard. The horizon and surrounding buildings are compressed into a hemispherical projection, demonstrating extreme radial scaling.Mostafameraji · CC BY-SA 4.0 · Wikimedia Commons08Fisheye lenses - Canon 8-15 "Sheikh Lotfollah Mosque" لنز فیش آی (چشم ماهی) 8-21 کانن، مسجد شیخ لطف الله اصفهانLooking up at a decorated ceiling through a fisheye lens. The radial distortion makes the straight architectural elements appear as concentric arcs, a hallmark of barrel lens warp.Mostafameraji · CC BY-SA 4.0 · Wikimedia Commons09Sprinkenhof (Hamburg-Altstadt).Innenhof.2.29135.ajbThe internal courtyard of the building is captured with an extreme wide-angle lens. The brick walls and window rows exhibit pronounced outward curvature towards the edges, demonstrating significant barrel distortion.Ajepbah · CC BY-SA 3.0 de · Wikimedia Commons10Hamburg town hallThis architectural photograph shows the town hall facade curving away from the center. The ground tiles and roofline display the typical radial geometric bending associated with barrel lens warp.Medvedev · CC BY-SA 3.0 · Wikimedia Commons
