First image - the musician and background are lit is such a way that it makes sense.
Second image - at first glance, this image looks like it could be a musician on a stage with stage lighting hitting him. If we look a couple of seconds longer, we realize the light reflecting off him looks like natural light, not the harsh stage lighting and we start to wonder if the photographer is trying to fool us.
Third image - the lighting looks implausible. The musician is lit far too brightly for the background to be that dark.
