Curiously Fourth’: As can be seen from the wrist watch the young lady is wearing I took this photo at around half past five in the evening. One of a group of people who appeared to be working on some kind of art installation – a carefully positioned and constructed shiny cube with blue LED patterns embedded into it and about the size of small fridge – began assembling a drone on a mini helipad. After photographs and video of their object were taken out came the drone for aerial imaging. Out of curiosity, I watched and waited until the third rotor was fitted and then pressed the shutter. A simple though attractive study in concentration.
