Avoiding light leaks
The long exposures needed with a Big Stopper can mean light leaking in places that you don’t usually expect. Jeremy has found that the focus distance window on some lenses can even leak in light. To cover everything, Jeremy now uses a custom-made dark cloth – a piece of leather with Velcro fastening, which he can wrap around the lens and camera. Not only does this stop light leaks, it protects the setup from salt spray.
