chosen time of day
For our OTS we had decided to film it in late afternoon in relatively well shaded areas. this meant, given that it was winter, it had already began to darken down and the shaded area's provided a bit more darkness to each scene. However due to the OTS being non-linear, it was acceptable to film at a slightly different time for some of the shots which may seem to be in a higher key of light. Most of the lighting effects were dealt with in post regardless of the lighting conditions on the day of film to provide a darkened atmosphere.
