FISHEYE VIEW OF THE BOTANIC GARDENS
MY HALLOWEEN VISIT TO THE BOTANIC GARDENS IN GLASNEVIN FORCED ME TO RETHINK MY APPROACH TO USING A FISHEYE LENS
It is going to take a long time for me to develop the necessary skills but I will keep trying.
One unexpected occupational hazard of pairing an extreme 180-degree field of view with the low Dublin autumn sun is that virtually every frame taken with the light behind me captured my own shadow. With the late-October sun hovering barely twenty degrees above the horizon, the fisheye optics stretched my silhouette into an absurdly elongated, gaunt figure creeping across the Victorian gravel and curling over granite kerbs.
At first, my instinct was to curse the optical intrusion; yet on Halloween, between the harvest squashes and the quiet borders near Glasnevin Cemetery, the exaggerated, cape-like shadow assumed an unmistakably vampiric presence. Rather than fight the lens geometry or attempt generative cloning across radial paving textures, I opted to leave the "vampire" intact—a theatrical, if accidental, nod to Samhain that firmly anchors the observer within the frame.
Escaping the Glasshouse Grid
The initial plan had been to exploit the vast interior volume of Glasnevin’s iconic Victorian glasshouses. In practice, the experiment unraveled quickly. The rigid architectural geometry—an intricate web of cast-iron ribs, vertical mullions, and rectilinear glazing—amplified the lens’s barrel distortion into visual noise. Every straight line twisted aggressively, producing a disorienting, warped caricature rather than an expansive portrait of the space.
Stepping away from the glasshouses, I retreated into the garden's wooded arboretum to reset my approach. Free from the constraints of engineered symmetry, I began testing how curvilinear optics interact with unrestrained organic forms—a shift that revealed an entirely different way to harness the lens.
Organic Geometry: Taming the Fisheye in Natural Landscapes
The principal obstacle when working with a curvilinear fisheye is psychological rather than optical. The human eye easily tolerates wide fields of view, but the subconscious recoils when familiar rectilinear references—lampposts, masonry lintels, and vertical window mullions—bend into pronounced arcs across the periphery.
In the natural landscape, that reference frame dissolves. Nature deals in gestures, rolling contours, and organic asymmetry rather than Cartesian grids:
Eliminating Structural Cues:
By deliberately framing to exclude man-made artefacts—fence lines, signposts, railings, and overhead cables—the barrel distortion loses its disruptive giveaway. Because an observer expects mature oak and beech trunks to twist, fork, and lean, curvilinear bending integrates seamlessly into the woodland's native character.
The Optical Axis Anchor: A fisheye renders any straight line intersecting the exact optical centre without curvature. Placing a dominant trunk dead-centre keeps it vertically true, allowing peripheral boughs to fan outward like the vaulted ribs of a Gothic nave.
The Canopy Dome: Tilting the lens slightly upward within dense woodland harnesses perimeter compression to draw the treetops inward. Rather than reading as optical warp, the composition replicates the immersive sensory experience of standing beneath a soaring forest canopy.
Proximity Without Corner Smear: Standard rectilinear ultra-wides (such as a 14mm or 16mm) preserve straight lines at the expense of severe anamorphic stretching near the margins. The fisheye’s equi-solid projection avoids this corner elongation entirely, allowing you to work centimetres from moss-covered roots or carpeted leaf litter with deep focus and consistent texture from edge to edge.
When stripped of artificial vertical cues, the fisheye ceases to be a novelty optic and functions instead as a serious environmental tool—capturing organic volume and atmosphere without betraying its extreme geometry.
