pentimentoRepentir is an augmented reality iPhone app that allows gallery visitors to reveal hidden layers of a painting. Using the app, you can take a photo of an area of a painting to browse previous versions of that area of the painting, which the artist captured over the course of its creation.

The aim of the project is to explore notions of authenticity and originality, by exposing the skillful, complex and prolonged creative process of the contemporary realist painter Nathan Walsh to gallery visitors who would otherwise only see his finished paintings.

Repentir is being developed as part of the EPSRC Digital Originals Project, in collaboration with Jo Briggs (Northumbria University), Nathan Walsh (Artist), Mark Blythe (Northumbria University) and Patrick Olivier.
