How to keep water spots off your port

This is the question I get asked more than any other. More than settings, more than housings, more than how to not get pounded on a bigger day. Someone buys a housing, swims out, shoots a great session, comes home, and every second frame has a fat water drop sitting right on the surfer's face. Then they search for the answer and find forum threads from 2011.

So here's the actual answer, the one I use on every swim, plus the honest alternatives, because my way isn't the only way.

Why spots ruin frames

A water drop on the front of your port is a lens in front of your lens. It shows up as a soft blurry blob in the frame, and a single one sitting over your subject can wreck an otherwise perfect shot. Water will always be on your port. You're in the ocean. The game is controlling when the port is clear, and that turns out to be a timing skill more than a gear problem.

What I do: the palm rub, and the timing

The short answer is I rub the palm of my hand across the front element while it's still underwater, before I need the port to be dry.

I anticipate the moment I'm going to need a clean port, so I start by wiping my palm across the front of it underwater, then lift the housing out right before I need to gain focus on the surfer. When I lift it after that wipe, I can watch the water bead right off the front. That's the whole trick.

It sounds simple, and the technique is simple, but the real skill is the anticipation: knowing when the port needs to be clear and doing the wipe a beat before that, not after. Get the timing right and you're lifting a clean port into the exact second your subject stands up and starts riding. It doesn't always work out perfectly, but the more you anticipate, the better your timing gets.

Notice what this method requires: knowing when the shot is coming. If you're reacting to moments, there's no time to prep the port and you're shooting through whatever happens to be on the glass. If you're reading the surfer paddling in and you know where their moment will happen, the wipe slots naturally into the beat before you raise the camera. That anticipation skill is the spine of everything I teach, and the port trick just rides along on it. If you want the bigger picture it lives inside, start with how I shoot from the water.

The other ways that work

That's my way. Not everyone will like it or prefer it, and that's fine. There are other good options, so pick the one that works for you.

A squeegee. Aquatech makes small squeegees, and some come on a little leash so they stay attached to your wrist. You wipe the water off whenever you need to. If the palm rub isn't clicking for you, this is a great option to try.

Candle wax. Some people rub candle wax on the front element. Take a small tea candle and draw a big tic tac toe pattern across the front of the port, then buff it off with your rashguard or whatever you've got on. That leaves a thin film that makes water bead off really fast. It usually lasts about 20 to 30 minutes before you have to reapply. Worth experimenting with if it sounds like your kind of thing.

Saliva. Some people just spit on the port and rub it in, and water beads off pretty easily. Simple, free, always with you.

Nose oil. I've heard of people using the oils from their nose on the front of the port. It's not something I do, but some folks swear by it.

Flat ports and domes behave differently

Worth knowing as you pick your method: on a flat port, droplets show up hard as blobs in the frame, so the clearing habit matters most there. On a dome, droplets matter less optically, but scratches matter more, so whatever you rub across a dome, make sure your hand is free of sand first. A sandy wipe is how you buy a new port, and a scratched front element ends a session real fast. If you're still choosing between flat and dome, my water housing article covers the tradeoff.

The habit, start to finish

Wipe your palm across the front element underwater before you need it clear. Lift the housing out right before you gain focus. Watch the water bead off, and shoot into the clean window. Rinse the housing in fresh water after every session so the glass stays clean at home. And build the anticipation that gives you the beat of warning the whole trick depends on.

For me it comes down to three things: the palm rub, the timing of when you do it, and being ready the moment your subject is up and riding. Nail those and water spots stop being the thing that ruins your best frames.

Nobody wrote this up properly because it's not a product and there's nothing to sell in a palm. But it's the difference between a session of keepers and a session of blobs, and it's yours now.

If you want the method this habit lives inside, the In-Water Technique Guide has the full chapter this article is drawn from, plus the anticipation and timing skills that make it work: reading the wave, picking your seat, the settings chapter, all of it. The port trick is a free taste. The guide is the meal.
