We rented a Blackmagic Pocket 4K, a colour chart and a gold light reflector from the kit room. We also later realised we needed a Ronin to stabilize the shot as it was such a tight shot that any small movement was noticeable.
then found a random assortment of shiny jewellery to use in the shot, as well as some stones, that I cleaned up. I also found some flint.
