But due to the fact that “it was so suturing dark,” Watson had to wait till dawn to take it photos.

“We sat about there till dawn, and valve Norman, chief engineer for bill Mulholland, came up v a truck and also said that take us up come the dam,” Watson said. “So we got in this truck and went increase there. We might barely watch it. I put my camera on a tripod, opened up mine lens wide to f4.5 and gave the 2-3 secs exposure.”
