It was an amazing place to be when the bats were leaving or returning to the roost, the sound of thousands of bats whistling past your ears and the occasional one crashing into your ears. I filmed much of this on and infrared converted Red Dragon, and I'm still amazed how well it coped at high frame rates in the infra red light. The bats' wings were translucent under the right lighting and looked stunning.
But for me, the highlight was filming the bats emerging at a famous cave called Frio, in Texas. It is vast. The first entrance is so big you could fit a 737 plane in there, it was perfect for our filming. There are estimated to be several million bats in that cave and the emergence is spectular. I had an Arri Amira and a canon 30-300 for the job and they didn't let me down. From where I was filming inside the cave I could see the huge number of bats congregating in the cavernous chamber before moving out to forage for insects. It was incredible, the sound of that many wings rushing around you and the moment they decide to leave the cave, the next spectacle starts as they snake across the landscape for miles.
It was a great team to be involved with and needed all the hands we had to get the logistics, planning, Vast amounts of equipment, and the shear determination against the odds to make it a successful sequence, oh and the enormous amount of gatorade to keep us going!!! So special thanks to the amazing team : Giles Badger, Rachael Norman, Jo Stead, Nickolay Hristov, Lou allen, Isaac Banks, and Chris.
