Petelko's photographic practice moves through states of transformation. Points where form
is dissolving into something else. The Shape of Undoing works by subtraction: removing detail, obscuring the recognizable, so that what remains is felt rather than described, a process informed by the artist's own experience of vision loss.
Located at the edge of landscape, where photographed form comes undone. These works ask the viewer to sit inside an unresolved moment rather than a resolved one, trusting that meaning gathers in what has been taken away, in the space between collapse and becoming.
These images are created using LiDAR technology rather than a conventional camera. LiDAR can be used by treating spatial data as image-making material. Instead of recording reflected light through a lens, LiDAR emits laser pulses and measures how long they take to return. This produces a three-dimensional “point cloud”: thousands or millions of measured points describing surfaces, distances, and forms.
