... Solargraphy involves using a pinhole camera to shoot extremely long exposures of scenes. Photographers who engage in it often leave their cameras fixed to outdoor locations for months or years in order to capture the path of the sun across the sky.
Waiting until the whole exposure is complete before seeing if an image turned out is painful enough, but there’s another major difficulty that can cause practitioners pain: the cameras are sometimes mistaken for bombs.
That’s what happened last Thursday over in Virginia. The Roanoke Police department received a report of a suspicious device strapped to one of the metal support beams of the Martin Luther King Jr. Memorial Bridge with zip ties.
By sheer coincidence, there was a memorial and prayer service for Martin Luther King scheduled to be held nearby later in the day, so the police didn’t want to take any chances. Thus, they treated the device as an extremely dangerous bomb.
