Rain. How we’d love to go inside and have a cup of tea when the old British precipitation interrupts a shoot, but quite often the schedule demands that we carry on regardless. Here are a few tips for filming in the wet stuff.

Cover the Camera

If you don’t have a proper rain cover, a transparent recycling bag with a couple of holes cut in it will usually do the job, but have someone hold an umbrella over the camera at all times as added protection. If you have them, put on a matte box and top flag to keep rain off the lens.

Check the Lens

Condensation may well be an issue. Have an assistant with a ready supply of dry lens tissues (in a ziplock bag), because a cloth will quickly get too damp to be of any use.

Look After the Lighting

Transparent recycling bags are perfect for covering LED panels, which don’t get hot.

Tungsten lamps get so hot that they burn off any water before it can do any damage, so as long as they’re switched on you don’t need to worry about them getting wet, but you should wrap the switch in a plastic bag.

The same goes for HMIs, though you’ll need to put a bin bag over the ballast. Make sure the bag is loose at the top, so that the heat from the ballast can inflate it and then dissipate through the bag; if you wrap the bag on tightly, the ballast will overheat and cut out.

People can be understandably concerned about mixing water with electricity, but honestly, I’ve run tungsten and HMI lamps in the pouring rain for hours without covering them, and never had any problems. If you’re really worried, clip a sheet of gel over the lamphead to make a little hood.

Use Outdoor Cabling

Ideally you should use only 16A (and above) cabling with C-form sockets (the round blue ones); these are rainproof. If you have to use domestic 13A extensions, wrap all the connections in plastic bags.

Seeing the Rain

The key to making rain show up on camera is backlight. If you want it to look like a real downpour, get your biggest HMI at the back of shot and blast it towards camera. Or maybe you don’t want to see the rain, maybe it’s bad for continuity, in which case you should avoid backlight at all costs.
