Light is essential for us to be able to enjoy colors. This is a shot I took one morning during Balloons over Waikato in 2011. Some of the balloons lifted off just before dawn, using some type of gas to glow in co-ordinated patterns. It was beautiful! And really hard for me to photograph. But I think this picture can give you an idea of how it looked.
