How to Avoid Water Droplets on Your Dome Port
Hey everyone,
Water droplets on your dome port are one of the most common frustrations in underwater photography. They are especially annoying when shooting split-level (over/under) images or working in surf and waves. A single bead of water can ruin an otherwise perfect frame with blurry spots, distortions, or unwanted reflections.
The good news is that this problem is very manageable. With the right preparation and a few proven techniques, water will sheet off your dome port evenly, leaving it almost invisible in your photos and videos.
Here is a practical guide based on methods that experienced underwater and surf photographers use successfully with their Salted Line waterproof camera housings.

1. The Classic “Wet Port” Method - Your Most Reliable Solution
The simplest and most common way to keep a Dome port droplet-free is to create a thin hydrophilic layer that turns beading water into a smooth sheet. The best solution? Your own saliva.
How to do it step by step:
- Before entering the water, spit generously on the dome and spread it evenly with your tongue (never use your fingers-skin oils can make things worse).
- Let the layer semi-dry for 5-10 minutes while you finish gearing up. Some photographers even apply a base coat the night before for better results.
- Once in the water, give the housing a quick dunk and lightly lick the port again to remove any thick spots.
- Keep your Salted Line waterproof camera housing fully submerged until the exact moment you are ready to shoot. Lift it smoothly, take the shot or burst, and dunk it straight back under.
This technique works because saliva reduces surface tension, so water clings as a uniform film instead of forming visible droplets. It is free, always available, and works extremely well with Salted Line camera housings during split shots or wave action.
2. Alternative Treatments When Saliva Isn’t Ideal
Not everyone likes the saliva method. Here are excellent alternatives that many divers and surf photographers recommend:
- A tiny drop of baby shampoo, mild eco-friendly dish soap, or a dedicated anti-fog solution such as Sea Drops.
- Specialized hydrophilic gels designed specifically for underwater ports.
Apply them in a thin, even layer, let them set briefly, then rinse lightly. Reapply during long sessions because these coatings can gradually wash off. A quick fresh-water rinse right before entering the ocean also helps remove any dust or residue that could cause streaking.
3. Smart Shooting Techniques That Make a Big Difference
Even with perfect preparation, your technique in the water plays a huge role:
- Dunk-and-shoot: Fully submerge the dome right before pressing the shutter, then lift it steadily into position.
- Move with the waves instead of fighting them - natural motion helps water run off instead of pooling.
- When possible, use a larger-diameter dome. Bigger domes make any remaining droplets smaller and far less noticeable in the frame.
- Shoot in bursts during the “sheeting” moment - you will often capture beautiful light refractions as a bonus.
4. Quick Fixes and After-Use Care
- If a rogue droplet appears, a quick dunk and light lick usually fixes it instantly.
- After every dive, rinse your Salted Line waterproof camera housing thoroughly in fresh water and let it dry completely in a shaded area. This prevents hard-water spots from forming over time.
Clear Ports Mean Better Shots
Dealing with water droplets on a dome port does not have to be a constant battle. A clean port combined with the wet-port method and smart timing will dramatically improve your results - whether you are capturing epic surf splits, colorful reef scenes, or dynamic wave action.
Salted Line waterproof camera housings are built with high-clarity dome ports precisely for this kind of creative shooting. Pair them with these simple habits and you will spend less time fighting droplets and more time creating the images you love.
Next time you head out with your Salted Line setup, try these steps and watch your keeper rate improve.
Keep This in Mind
Please keep in mind that there is no single technique that can guarantee 100% elimination of water droplets in every situation. The best approach is to experiment with the methods above and discover what works best for your particular setup.
