Aaron Park, May 14, 2014 (welders glass experiment #2)

This is a 310 second exposure (five minutes, 10 seconds). To get a exposure time this long I used a piece of welders glass for a 13 stop ND filter.

I turned it into a black and white photo as the edges of the photo was turning purple. I assume this was caused by the sensor getting too hot during such a long exposure. The photo also suffered from hot pixels.

310.0 seconds at F4.0 with an ISO of 1250. Canon 5D mkIII, Canon EF24-105mm f/4L IS USM lens.
