"I managed to get myself onto the image in 3 locations whilst scribing "WPPD" in the air with a hand held lamp. Exposure time ~3 minutes. The images were blended in-camera onto photopaper using a double pinhole home-made camera. The double image pops into 3D when viewed with eyes crossed."
"The camera was made from a discarded lozenge tin; focal length ~20mm; f~100."
