Filming in Summer House in the evening

We left college at 4 o'clock in the hope of getting to the location in Lilleshall at sunset but not too dark to film. But as it gets dark so quickly at this time of year we didn't get there and start filming in time, so it was too dark. We tried using a torch to shine on me whilst i ran through the door, but it still wasn't enough and we'd have continuity issues and couldn't see the effect of it being a dusty room. Also the green screen footage we'd got earlier in the day wouldn't fit, because the lighting wouldn't be the same. But this did give me chance to introduce this location to the person I'm working with and she agreed that it was the right location for our video.
