So, I'm photographing the RNC for Silicon Alley radio. Wednesday night, George H. W. Bush is in the presidential box with Barbara and Zell Miller. I knew it would probably be my photo of the night. Problem was, they were sitting down and I could only see them from the nose up. I cleverly realized that at the end of the Ronald Reagan tribute video, they would all stand up and applaud, so I staked out a great spot on the floor and waited. At the end of the video, the lights came on and sure enough, Zell, President Bush and Mrs. Bush all stand up to applaud! I frame my shot, but, what the heck! There's this white blob covering the bottom of the picture! What could it be that ruined my photo??
