It is entitled "ages of life". The 4 photographs represent women of different ages who walk or run in the same direction: a little girl walking with her mother (the photo is taken in the morning); a young woman walking and listening to music (the photo is taken later in the morning); a mature woman running at full speed (the photo is taken during the day) and an elderly woman who keeps running (the picture is taken when the shadow wins the picture). This is the first photo of the series.
