Another day, another exhibition.  Today I dropped in to the Tate Modern to see the latest commission for the turbine hall: Tacita Dean's FILM, shot and edited on celluloid, unsurprisingly, then projected 42 feet high, sprocket holes left unmasked to enhance the allusion.  Some photographers hold on to a nostalgia for flammable plastic and I do occasionally miss the element of surprise that working in a darkroom involved, but for me, digital acquisition, processing and publishing (eg to here) continues to open up possibilities that can never exist in the analogue world.
