Fionnbharr Ó Súilleabháin’s photography techniques hark all the way back to the 19th century. He makes calotypes (paper negatives) using 100-year-old lenses on large box cameras. Together we made “Human Mist”, Fionnbharr’s book of landscapes and architectural pictures, including his pithy commentaries on how the photos were taken. Despite the fact he lives in Mozambique and I in Dublin, we worked together just fine over email, file transfer and Twitter, the most modern of electronic communications.
