Went to the Union county OH Balloon Fest last weekend. It did not start well with bumper-to-bumper traffic on a 2-way road. By the time I reached there, most balloons had taken off. To make matters worse, my new used lens turned out to be a lemon; missed a few good shots.
I did manage to get some shots later in the evening but it was technically very challenging. The balloons would lit up randomly in otherwise a pitch dark scene thus making obtaining a good exposure extremely difficult.
