SOFT EDGE OF REALITY
Definition: ‘Photogrammetry is the science of making measurements and 3D models from photographs.’

During his time as a researcher at Forensic Architecture, Stefan Laxness used photogrammetry as an operative tool to recreate accurate 3D models of locations where human rights abuse had been committed. In other instances, Forensic Architecture has used photogrammetry to reconstruct site models from drone footage and to archive destroyed heritage sites.

In ‘Soft Edge of Reality’, Stefan Laxness inverts the gaze of the camera, to explore how the same process can capture, present and archiving questions of domesticity, intimacy, memory and the passing of time.
Photogrammetry offers yet another tool for recording and archiving every bit of data produced by our day to day lives. However, unlike the single frame of the photograph, the photogrammetry model allows the viewer to explore a plurality of frames, revealing the edges of a scene - its underside, its vulnerability.
The photogrammetric process creates an accurate reconstruction of the scene, capturing scale, form, texture and environmental conditions, but the process is also incomplete. Areas hidden to the lenses of the camera, complex textures and reflections, produce voids and distortion left for the algorithm to interpret which in turn create distortions.
Like memory, the model registers distortions that prevent the full reconstruction of an incident. The accumulation of models produces a digital library of soft memories. It interrogates how these technologies accelerate rates of spatial preservation and the role new digitised realities play as objects of mediation between people, space, past and present.
