There were 204 photo printing labs in and around London in 2006, printing images from film stock to paper. By 2009, only six remained.
In each of these labs’ darkrooms were photo enlargers, themselves quite large, that projected the images from film negatives onto a piece of photo paper. Richard Nicholson’s series Analog — The Last One Out, Please Turn On the Light is a requiem for these hulking machines, now gradually wending their way to obscurity and landfill.
