Dawn and I had WAY too much fun tonight doing nighttime photography. The top picture was done by exposing for the dome/sky and then off camera flash to get the flowers and path lit up. Super easy. The macro flowers were done in the dark, with the 320EX flash LED light turned on and held on the opposite side of the leaf. The bottom picture was taken with the 1D and 20-35L lens.....I am very pleased with how it turned out - considering that the only thing that you can review is the histogram!
