I love photographing silhouettes. There is something about dark figures against a colorful background. Second best are shadows and this video starts out simply enough with the violinist’s shadow projected on a board behind her. Everything is fine until the shadow decides to do its own thing! The change happens at around the 0:34 mark but even at 0:17, observant eyes would have noticed a lag, indicating it is not really her shadow (or it is, but filmed separately and edited back together). Beautifully played!
