I was shooting a video with a dancer, and between takes, she sat down to adjust her shoes. My eye immediately saw the wonderful play of light on her form, and I asked her to wait for a moment while I grabbed a still camera. We shot just five frames, and then we went back to shooting video.
One of the keys to successful imaging is watching for how light creates volume, shows texture, and affects color. So always be observant in experiencing the world, and of course, always have a camera ready when you see something special.
