Returned to the location late afternoon the next day for more shots of the completed work. Short window in which to shoot, from the moment the sun dips behind the mountain, removing the direct rays of light falling through the tree cover onto the work, to the moment when the light becomes insufficient for the sensor. Also did some test shots with a small drone to assess whether shooting with a larger drone equipped with a higher-quality camera at a later stage could potentially add to our portrayal of the work and the meaning and impact of this sequence in the film.
