Bayer arrays? Anti-aliasing filters? Megapixels? Sweep Panoramas? Some prefer to keep it old school with 6×6 medium format film. I came across this guy shooting the streets with his trusty Pentacon Six, a medium format Single Lens Reflex (SLR) developed in Germany in the 1950s, and manufactured till the early 1990s. He happily obliged to have a portrait taken with his camera. Just round the corner, another tourist was Instagramming away on his smart phone.
