When diving with underwater camera housings, one common issue many photographers encounter is fogging in underwater housings. This problem occurs due to the temperature difference between the housing, which is exposed to sunlight, and the cooler water.

The Science Behind Fogging

Fogging occurs due to basic physics. When the housing is left in the sun, it heats up. Upon entering the cooler water, the sudden drop in temperature causes condensation to form inside the housing. This is because warm air holds more moisture than cool air. As the temperature drops, the moisture in the air inside the housing condenses on the cooler surfaces, including the camera lens, leading to fogging that obstructs the view and ruins your shots.

How to Prevent Fogging

To minimize fogging, it’s crucial to manage the environment around the housing. One of the golden rules is to avoid exposing the housing to direct sunlight before the dive. Always keep it in the shade or cover it with a towel when you’re on the beach. Additionally, it’s important to load your camera into the housing in a dry environment, away from the humid beach air, as moisture trapped inside can exacerbate the fogging problem.

While fogging can occur in all types of housings, acrylic housings are particularly prone to it due to their insulating properties. Aluminum housings perform slightly better, as metal dissipates heat more effectively, but the same principles apply.

Additional Solutions

One of the most effective ways to prevent fogging is to use silica gel packs inside the housing. These small packets absorb moisture from the air, keeping the internal environment dry. Most divers use this solution to ensure their housings remain fog-free throughout the dive.

By taking these precautions, you can prevent fogging and ensure a clearer, more enjoyable underwater photography experience.

In this guide, we’ll go over basic steps to your maintaining underwater photography equipment, including daily cleaning and long-term storage. You’ll find practical tips to prevent corrosion, avoid damage, and keep your camera and accessories in good condition for clear, consistent images.

Introduction to Underwater Photography Gear

For underwater photography, you need some pretty specific gear to capture clear images in the water. This usually includes things like waterproof camera housings, special lenses, strobes or underwater lights, and other add-ons like wet lenses and port covers. Each part needs regular care and attention to handle underwater conditions, like exposure to saltwater and the pressure changes that come with diving.

Why Maintenance is Important

It takes some of your precious time to maintain your gear underwater, but the results will pay off in better shots and a longer-lasting setup. Easy routines to get into at the end of every dive include rinsing, lubricating O-rings, and storing correctly to ensure that your equipment is always ready for the next dive. Being consistent with them will provide years with your gadget at peak performance.

Basic Tools for Maintenance

To maintain your underwater photography equipment effectively, you’ll need a set of basic tools and cleaning materials. Here’s a quick list:

• Freshwater rinse container: Large enough to soak and rinse equipment post-dive.
• Soft microfiber cloths: For gently wiping lenses and screens.
• Air blower: Handy for drying hard-to-reach areas without scratching surfaces.
• Lens cleaning solution: Alcohol-free to prevent residue on optics.
• Silicone grease: Essential for lubricating O-rings without damaging rubber.
• Protective case: For safe storage and transport of delicate parts.

Having these on hand will simplify maintenance, ensuring you can clean, dry, and inspect your gear after every dive.

Pre-Dive Preparation

Before heading out on a dive, it’s essential to inspect and prepare your gear meticulously.

Inspect and Assemble
Check for any apparent damage to your housing, the ports, and other parts. Pay extra attention to the O-rings; those are your main seals and guards against leakage. When everything seems okay, begin to assemble your camera and equipment, following instructions from the manufacturer closely.

Test Waterproof Seals
Make sure every latch is closed and tightly fastened. You can even dunk the housing (without a camera inside) in freshwater to check that everything is waterproof. This small test generally gives one confidence in confirmation that seals work right, so you will be diving confidently.

Daily Cleaning Routine

After each dive, cleaning your equipment is the most important step in maintaining it. Salt, sand, and other particles can build up and damage your gear if left unattended.

Rinse with Freshwater
Freshwater rinse your gear immediately after a dive. If time allows, let it soak for several minutes as this will allow any remaining salt to dissolve. The longer the dive, or the saltier the environment, the longer the soak will be to more adequately remove all of the particulate.

Clean Optical Components
After rinsing, gently wipe down lenses, ports, and screens with a microfiber cloth. Steer clear of abrasive materials, as they can scratch the glass or damage any coatings.

Preventing and Managing Corrosion

Saltwater exposure is the most common cause of corrosion, which can quickly degrade even the best underwater photography gear. To prevent this, follow these practices:

• Regular freshwater rinsing: Never allow saltwater to dry on your equipment.
• Dry thoroughly: Use an air blower to dry crevices and joints.
• Avoid harsh cleaners: Chemicals may damage coatings and O-rings.

Lens and Port Maintenance

Lenses and ports are critical to image quality, so extra care is needed.

Cleaning Lenses and Ports
Use a soft microfiber cloth to clean the lens and port surfaces, ensuring they remain free from smudges and residue. Avoid direct handling with bare hands to prevent fingerprints.

Protecting Glass and Acrylic Ports
If you are not using your equipment, a port cover can be set on the port. In terms of cleaning, for glass ports special cleaning solutions are appropriate while acrylic ports should be treated more carefully to avoid scratches.

Handling Seals and O-Rings

O-rings are the linchpin of underwater equipment. A faulty or dry O-ring can lead to catastrophic leaks.

Inspecting and Lubricating O-Rings
Before every dive, check the O-rings for nicks or debris. Apply a small amount of silicone grease to keep them supple and effective, but avoid over-greasing as this can attract particles.

Avoiding Common O-Ring Mistakes
Using the wrong grease or neglecting to clean O-rings properly are common mistakes. Follow your gear’s specific guidelines to avoid these errors and keep your O-rings in top condition.

Battery Care and Management

Battery care is essential for reliable performance underwater.

Choosing the Right Battery Type
Use manufacturer-recommended batteries to ensure optimal performance and battery life. Avoid low-quality batteries that might swell or leak under pressure.

Battery Compartment Maintenance
Keep battery compartments clean and dry. Before inserting, wipe down batteries to remove any particles, and always check for a tight seal after closing the compartment.

Storage Practices for Longevity

Proper storage can significantly extend the life of your underwater photography equipment.

Store in Cool, Dry Places
Humidity can damage electronic components, so store your gear in a cool, dry place. A desiccant packet inside the storage container can help manage moisture.

Avoiding Extreme Temperatures
Extreme heat can affect battery life and damage seals, while extreme cold may cause condensation. Try to maintain moderate storage conditions.

Travel Tips for Underwater Gear

Traveling with underwater equipment requires special care.

Packing Tips for Safe Travel
Padded cases are for sensitive components. Separate batteries and other sensitive parts against the impact caused by bad roads and vibrations when packing.

Flying with Batteries
Airlines may have restrictions in terms of type and number of batteries in carry-on baggage. Always verify ahead of time if there are any new regulations. Lithium-ion batteries are often restricted and must be properly packaged to prevent short circuits.

Troubleshooting Common Issues

Knowing how to troubleshoot issues can save time and prevent permanent damage to your equipment.

Leaks and Condensation
If you notice leaks, stop using the equipment immediately. Remove the camera, dry it thoroughly, and inspect all seals. For condensation, check for any temperature differences or humid environments in your setup.

Fixing Fogged Lenses
Fogged lenses are usually due to temperature differences. Try using anti-fog inserts inside the housing to prevent this issue from affecting your photos.

Conclusion and Final Tips

Keeping your underwater photography gear in good shape may take some time, but it’s worth it for better shots and a longer-lasting setup. Simple routines like rinsing after each dive, lubricating O-rings, and storing everything properly help make sure your equipment is always ready for the next dive. Sticking with these habits will help you get the most out of your gear for years.

On ships, Zinc coating is being used as an efficient solution against Marine and Offshore corrosion.
The hull of a ship is the watertight body that is exposed to water, just like your housing is to your camera.

To protect the hulls, the shipbuilders put pieces of Zinc on these hulls. The Zinc components used on ships are called “Sacrificial Anodes”.
They are made of metals that are more reactive than the material used for the ship’s body and systems. So as such, they shield the ship’s body and systems while the ship stays protected.

Why does this happen?
Zinc is used because it has a higher voltage in the water so the current is more inclined to flow from it than from the propeller. To complete the electrical circuit, Zinc components are connected to the items they are intended to protect. Zinc is bolted right to the shaft of the ships hull – and the same way it needs to be mounted directly on your underwater housing.

So to help prevent galvanic corrosion of the housing simply install in onto a part of your housing that is exposed to water.

Most housings already have these anodes mounted.

Remember, the Zinc material will erode sacrificially over time during deployment.
So you might need to exchange it after some years.

1) The flexarm system (often made by Locline units) and…
2) The alu-arm system (made by aluminum pieces with arm balls at the end.

How flexible??
It is a clear misconception that flexarms are more flexible than the aluarmes.
Aluarme is far more reliable and it is possible to attach e.g. a lensholder to them and you can trim them with floaters (StiX).
When you just get used to the use of clamps and how hard they are to be tightened, you discover how good a system alu-arms really are.

Especially on a camera that needs to do macro, a flexible and reliable arm system is evident.
Here you really need to be able to put the light as you like – and wouldexpect it to stay in place.

Float arms
The metal arms are more heavy, so it is a good idea to mount some floats on them.The StiX floats are the easiest and cheapest way to get your entire system buoyant.

But it is also possible to add an arm with “build in floats”
Those arms come from different brands and in different size depending on the amount of lift you need them to give.Always remember that alu-arms are put together with a clamp and that thick float arms should have a long clamp in order for the arms to bens together.
It is the price and weightFlexarms have the advantage that they are a cheaper investment overall and that they weigh much less, which can be important for someone who wants to go on a diving trip and have limited weight capacity.

Note:
Almost all experienced underwater photographers use aluminium-arms.

Underwater photography relies heavily on specialized equipment, and one of the most critical components is the glass lens. These lenses, crafted from low-dispersion optical-grade glass, offer exceptional clarity and performance when diving with them in front of your camera lens. Enhanced with anti-reflective coatings, these wet-lenses minimize optical challenges such as chromatic aberrations, spherical aberration, and field deformation, ensuring good underwater macro photography results. Housed in rugged, anodized aluminum casings and nitrogen-purged to prevent fogging, these lenses are built to withstand the harsh underwater environment. However, proper maintenance is essential to preserve their performance and lifespan.

Why Proper Maintenance Matters

Despite their robust design, underwater lenses are vulnerable to staining if not cared for correctly. When water – even fresh water – dries on the glass surface, it can leave mineral deposits and stains that are difficult to remove. These deposits can interfere with the lens coatings, compromising the image quality and potentially damaging the glass over time. To keep your lenses in pristine condition, it’s crucial to adopt an effective cleaning routine.

If your glass lens has been stained, it is unlikely you can clean the glass again.
You then need to get the front lens changed.

Best Practices for Cleaning Underwater Glass Lenses

1. Rinse Immediately After Use
   After completing your dive, rinse the lens thoroughly with fresh water. This step removes salt, sand, and other debris that could scratch or stain the lens. Using lukewarm water is particularly effective in dissolving salt crystals. (not too warm, and NO soap must be used)
2. Dry Completely with a Synthetic Fiber Cloth
   Drying is as critical as rinsing. Use a synthetic microfiber cloth, which is both soft and absorbent, to gently remove all water from the lens. This step ensures no water remains to evaporate and leave behind mineral stains.
3. Avoid Air Drying
   Never allow water to dry naturally on the lens. As it evaporates, minerals in the water can crystallize on the surface, causing stains and potentially harming the delicate coatings.
4. Inspect for Streaks or Residues
   Once dry, inspect the lens under light to ensure no streaks or water spots remain. If you notice any, re-clean with a damp microfiber cloth and dry thoroughly.

Pro Tips for Long-Term Lens Care

• Invest in a Lens Cap
  Protect your lens when it’s not in use by always securing a lens cap. This simple step prevents accidental scratches and keeps debris away from the glass.
• Store in a Safe Environment
  Store your lens in a cool, dry place, ideally in a protective case. This minimizes exposure to humidity and physical damage.
• Avoid Abrasive Materials
  Never use abrasive cloths, tissues, or cleaning agents that could scratch or degrade the glass surface.

The Impact of Good Maintenance

By following these straightforward yet effective cleaning practices, you ensure your underwater glass lens remains free of stains and scratches, allowing you to capture clear and vibrant images dive after dive. Proper maintenance not only preserves the performance of the lens but also extends its lifespan, saving you the cost of premature glass replacements. Remember, the key to great underwater photography starts with pristine optics. Take care of your lens, and it will take care of your memories.

If you still get a faulty lens it is possible to exchange the glass. But it is not cheap as the lens is full of nitrogen and needs to get refilled under completely dry conditions.
