"If it looks overlit, you pull the audience out of what they're looking at. Light coming from below is not normal. It's not natural," shares underwater DP Ian Seabrook CSC on capturing The Rescue and why getting the light wrong underwater is easier than most people think.
One of the most common mistakes people starting out? Overlighting out of fear of not seeing anything at all. And getting the color right is another challenge: "If you simulate the color of the water in the light, it doesn't look lit. It kind of blends in together."
For the cave sequences, Ian wrapped Helios Tubes in chocolate and coral gel filters with strips of black 2-inch gaffer tape cut into thin slits to shape the beam. Running around 3200K, they threw just enough light to reveal the cave walls without ever feeling artificial.
