"This image was taken with a Canon 5D Mark III digital SLR camera and a homemade 0.26mm silver pinhole mounted to the inside of a Canon body cap giving an effective "focal length" of 48mm. I had my camera mounted on a tripod and used a timer. Took three bracketed exposures at ISO 800 on aperture priority – 6 seconds @ -0.5, 2 seconds @ - 2.0, and 15 seconds @ +1. Images combined in Photomatix Pro. Final combined image edited in Adobe Camera Raw. Then used Topaz DeNoise AI and Topaz Sharpen AI plus NIK Viveza."
