Revealing the unseen

Infrared Reflectography (IRR) is a non-invasive method of studying a painting by looking beneath the visible layers of paint, allowing you to examine the underdrawing along with any changes or pentimenti present in the work.
The modern InGaAs sensor technology used in Apollo and Osiris cameras allows us to build on these techniques with exceptionally high resolution images and improved sensitivity to reveal a painting’s secrets like never before.
