There is nothing worse than an underwater camera housing that always fogs up. Luckily, there’s a few quick and simple steps to consistently keep your camera housing from fogging up.
1. Keep the Housing Dry
Keeping any amount of moisture out of your camera housing is the quickest and easiest way to maintaining a fog free underwater housing. Any time you are opening up or closing the housing, or even just cleaning the o-ring, you need to be particularly aware of every single drop of water. If you close the housing up with just a drop of water inside that water will quickly turn to into water vapor once the inside of the housing heats up as you being shooting underwater.
2. Keep the Housing Cool
Since it is quite likely that there will be a small droplet of water hiding in the housing somewhere, it’s always a good idea to keep the housing in a shady place any time your are in between snorkels. Also, any time you are aren’t using it underwater, try and keep the camera turned off so that the heat the camera emits when it’s constantly on wont’ vaporize any water droplets inside.
3. Be Careful with Air Conditioning
If you leave your housing sitting in an air conditioned environment, like your bungalow, then take it outside into the tropical heat, you are going to notice the housing will fog up immediately. It’s always a good idea to give your camera and hosing a few minutes to acclimatize to the tropical heat before closing everything up. Of course, don’t just hold it in the sun, but find a nice shady place for everything to adjust to the different temperatures.
4. Silica Packets
These little silica packets are handy, but if you aren’t following the first three rules I mentioned then they just aren’t powerful enough or fast enough to battle larger amounts of fog. If you follow rules one through three before and after every snorkel then there is really not much need for the little packets of silica gel.0
