Widjaja blindfolded digital cameras to perform photography of muons - invisible, extraterrestrial radioactive particles that pass through matter and bodies. CMOS image sensors, common in smartphones, detect visible light as well as ionising radiation photons such as muons that collide into the sensor plates. To record the muon traces, Widjaja blindfolded a CMOS device to block off light - turning it momentarily into an unseeing sensing instrument - and applied a code to filter muonic signals on the sensor. The muon signals are then transformed through a photographic technique that Widjaja had developed - through an analogue manipulation of an inverted camera lens - to produce a series of muonic marks that bear his micro movements and his imagination of a vast cosmic distance.
