In this solo show Bart answers friend of the show Allison Sheridan's deceptively simple listener question – 'why 35mm?'. This takes us on a journey from Thomas Edison and the Eastman Kodak company to Leica, Henri Cartier-Bression, Nikon, and eventually DSLRs, Micro Four-Thirds, and full frame sensors. Along the way we demystify some photographic jargon like 'crop factor' and EFL.
