Black and white photo of the speed calibration strobe on homelesstaco's Technics SL-1210MK2 turntable. I've watched (and sometimes helped) him use his turntable so many times and I'm always fascinated by the engineering that went into such a seemingly simple device.
Shot with a Canon PowerShot SX120 IS, f/8, 4 sec, ISO 80, 12mm focus.
