Protecting sensitive equipment from the ravages of moisture is crucial for their longevity and functionality. One might often come across terms like ‘dry box’ and ‘dry cabinet,’ but what are they, and why do they matter crucial?
What is a camera dry box?
A camera dry box is a sealed storage container designed to protect camera equipment from moisture and humidity. It often contains desiccants, like silica gel, to absorb moisture, preventing fungal growth and corrosion on lenses and camera bodies.
A dry box is well worth it for photographers in humid climates to maintain their gear’s longevity.
What is a Dry Cabinet? What is a Camera Dry Box Used For?
A dry cabinet, also known as a camera dry box, is a storage solution designed to protect sensitive equipment from harmful environmental conditions, particularly humidity.
A dry cabinet or camera dry box is great for anyone looking to protect their sensitive equipment from the damaging effects of humidity. It provides a controlled environment that helps prolong the life and maintain the stored items’ quality.
Here’s an explanation of each term individually
A dry cabinet is designed to maintain a specific level of humidity, which is lower than the ambient humidity. This helps in preventing the growth of mold, fungus, and other harmful agents that can damage sensitive equipment.
While dry cabinets are popularly used for storing cameras and lenses, they are also used for storing other sensitive equipment like musical instruments, electronic components, and archival documents.
Most dry cabinets use a desiccant, electronic dehumidifying system, or a combination of both to maintain the desired humidity level. The user can usually set the desired humidity level, and the cabinet will work to maintain that level.
Many dry cabinets come with built-in hygrometers that display the current humidity level inside the cabinet.
Camera Dry Box
A camera dry box is a specific type of dry cabinet designed primarily for storing camera equipment.
Cameras and lenses are precision instruments that can be adversely affected by excessive humidity. Fungus can grow on the lens elements, and moisture can seep into the camera body, leading to malfunctions.
Photographers, especially those living in humid climates or those who frequently travel to such areas, use camera dry boxes to store their equipment when not in use. This increases the longevity of the equipment and maintains its performance.
How Does A Dry Cabinet Work?
A dry cabinet, often used interchangeably with the term “dry box,” works by maintaining a controlled level of humidity inside the cabinet, ensuring that the environment is not conducive to the growth of mold, fungus, or other harmful agents. It is a sealed storage container designed to maintain a low-humidity environment.
The primary goal is to keep the humidity level lower than the ambient environment, especially in regions with high humidity.
A dry cabinet works by either absorbing moisture from the air or by cooling the air to condense and remove moisture. The choice of system (desiccant, electronic, or hybrid) depends on the specific requirements of the user and the items being stored.
Here’s how a dry cabinet achieves this:
This system uses a desiccant material, such as silica gel, to absorb moisture from the air inside the cabinet.
Over time, the desiccant becomes saturated and loses its effectiveness. Depending on the type of desiccant used, it must be replaced or regenerated (by heating or other methods) to restore its moisture-absorbing properties.
Desiccant-based systems are silent and don’t require electricity, making them energy-efficient.
Electronic Dehumidifying System
This system uses a Peltier cooler (or thermoelectric cooler) to cool the air inside the cabinet. As the air cools, moisture condenses and is collected in a tray or drained.
Electronic systems require minimal maintenance, but the water collection tray does need to be emptied periodically.
Electronic systems offer more precise control over humidity levels and can quickly reduce humidity when the cabinet is opened and closed.
Some dry cabinets combine desiccant and electronic systems to guarantee optimal humidity control.
Most dry cabinets come equipped with a hygrometer, an instrument that measures the humidity level inside the cabinet.
This allows users to monitor the internal humidity and adjust settings if necessary.
Dry cabinets are designed with airtight seals so that external air doesn’t easily enter the cabinet once the desired humidity level is achieved. This helps maintain a stable environment inside.
The effectiveness of the seal is essential. A weak or compromised seal can allow external air to enter, reducing the box’s effectiveness.
Many dry cabinets allow users to set a specific humidity level based on the items being stored.
Camera equipment needs to be stored at a different humidity level than delicate paper documents or other electronic components.
Do I Need a Dry Cabinet For My Camera?
Whether you need a dry cabinet or dry box for your camera depends on several factors, including the climate you live in, how often you use your camera, and where you store it.
Not every photographer needs a dry cabinet or box, but it’s a worthwhile investment for those living in humid environments or those with valuable equipment.
Even in moderate climates, having a controlled storage environment can provide peace of mind and expand the longevity and performance of your camera gear.
Here are some considerations to help you decide.
Climate and Humidity
A dry cabinet or dry box is highly recommended if you live in a region with high humidity, mainly tropical or coastal areas.
High humidity can lead to fungus growth on the lens elements and internal parts of the camera. Fungus not only degrades image quality but can also permanently damage the lens or camera sensor.
Even if you live in an area with moderate humidity, seasonal changes can introduce periods of high humidity. In such cases, having a dry storage solution can be beneficial.
Frequency of Use
If you use your camera frequently, the constant exposure to ambient air can help prevent fungal growth to some extent. However, proper storage still matters when the camera is not in use.
Using your camera infrequently makes it more susceptible to moisture-related issues, making a dry cabinet or dry box more beneficial.
A dry storage solution is advisable if you store your camera in a basement, attic, or any place with poor ventilation and fluctuating temperatures. These areas can trap moisture, increasing the risk of fungal growth.
Value of Equipment
If you have invested in high-end camera equipment, it’s wise to protect that investment with proper storage. A dry cabinet or dry box can extend the lifespan of your gear and maintain its performance.
Type of Storage
Dry Cabinets offer more precise control over humidity level but usually aren’t very portable. It’s suitable for those with multiple camera bodies, lenses, and other sensitive equipment.
Camera Bags are more portable and don’t require electricity. It’s suitable for those with limited equipment or needing a mobile storage solution. Throw in some silica gel packets to control the moisture.
Other Sensitive Equipment
If you also have other moisture-sensitive items like vintage film, electronic components, or archival documents, a dry cabinet might be a more versatile solution.
Where Do You Put a Dry Box?
The placement of a dry box can determine its effectiveness and help to protect the items stored inside.
The ideal location for a dry box is a cool, stable environment away from direct sunlight and potential sources of moisture. Proper placement improves the longevity and effectiveness of the dry box and the protection of the items stored inside.
Here are some guidelines and considerations for placing a dry box:
- Away from Direct Sunlight: Place the dry box in a location where it won’t be exposed to direct sunlight. Prolonged exposure to sunlight can increase the internal temperature of the box, which can affect its ability to maintain a stable humidity level.
- Stable Temperature Area: Choose a location with a stable temperature. Avoid areas near heaters, radiators, or air conditioning vents, as these can cause temperature fluctuations.
- Avoid Damp Areas: Do not place the dry box in inherently damp areas like basements or bathrooms unless you’re certain that the box can handle the high humidity levels of these locations.
- Elevated Surface: If possible, place the dry box on an elevated surface or shelf. This reduces the risk of water damage from spills or flooding.
- Ventilation: While the dry box is designed to be airtight, it’s still a good idea to place it in a well-ventilated area. That way, when you open the box, the surrounding air is relatively fresh and not overly humid.
- Easy Access: If you access your camera or other equipment frequently, place the dry box in a location that’s easily accessible. This way, you won’t be discouraged from using your equipment because it’s hard to reach.
- Safe from Physical Damage: Keep the dry box is in a location where it won’t be knocked over or bumped into frequently.
- Away from Children and Pets: Continuing on from the last point, if you have children or pets, place the dry box in a location where they can’t easily access or tamper with it.
- Space Consideration: Make sure there’s enough space around the dry box for opening its door or lid without obstruction.
- Check Regularly: Regardless of where you place it, make it a habit to check the dry box regularly. Monitor the humidity level (if it has a hygrometer) and confirm the desiccant is still effective.
What Should The Dry Box Setting Be For a Camera?
When using a dry box (or dry cabinet) to store camera equipment, the primary goal is to prevent fungal growth and moisture damage. The ideal humidity setting for storing camera equipment typically falls within a specific range.
What Is The Optimum Humidity For Camera Storage?
For camera equipment, aim for a humidity level of 40% to 50% in your dry box or cabinet. Regularly monitor the humidity and make necessary adjustments to maintain this range, prolonging the longevity and performance of your gear.
Camera equipment, including lenses and bodies, is best stored at a relative humidity (RH) level of 40% to 50%. This range is considered optimal because it’s low enough to prevent fungal growth but not so low that it risks drying out the lubricants in the camera or lens mechanisms.
If your dry box or cabinet comes with a built-in hygrometer (a device that measures humidity), monitor it regularly to see that the humidity remains within the desired range.
If your dry box doesn’t have a built-in hygrometer, consider purchasing a separate digital hygrometer to place inside the box. This will allow you to monitor the humidity level accurately.
Depending on the design of your dry box or cabinet, you might have manual controls or digital settings to adjust the humidity level. If the humidity goes above the recommended range, adjust the settings or replace/regenerate the desiccant to bring it back within the desired range.
If your dry box relies on desiccants like silica gel to absorb moisture, know that these desiccants can become saturated over time. When this happens, they need to be replaced or regenerated (often by baking in an oven, depending on the manufacturer’s instructions).
Some silica gels change color (e.g., from blue to pink) when saturated, providing a visual indicator that they need to be regenerated or replaced.
If you live in an area with significant seasonal humidity changes, you might need to adjust the settings or check the dry box more frequently during particularly humid months.
How To Use A Dry Cabinet For Camera Storage
Using a dry cabinet for camera storage is an effective way to protect your camera equipment from moisture-related damage, especially in humid environments.
Here’s my step-by-step checklist on how I use a dry cabinet for camera storage
- Choose the Right Size:
Depending on the amount of equipment you have, select a dry cabinet that can accommodate all your gear with some room to spare. This allows for better air circulation and future additions to your equipment.
Place the dry cabinet in a location away from direct sunlight, heat sources, and areas with high traffic to prevent accidental bumps.
Place the cabinet is on a stable surface to avoid any risk of it tipping over.
- Initial Setup:
Plug in the dry cabinet (if it’s an electronic type) and let it run for several hours to stabilize the internal environment before placing your equipment inside.
If your cabinet has a built-in hygrometer, monitor the humidity level until it reaches the desired range (typically 40% to 50% RH for camera storage).
- Adjust Humidity Settings:
Set the desired humidity level using the cabinet’s controls.
Check the hygrometer regularly, especially in the beginning, to confirm the cabinet maintains the set humidity level.
- Storing Your Equipment:

Store lenses vertically, and if possible, use lens pouches or dividers to prevent them from touching each other.
Leave some space between items for better air circulation.
- Regular Maintenance:
Periodically check the hygrometer to ensure the humidity level remains within the desired range.
If the cabinet uses a desiccant, monitor its effectiveness. Some desiccants change color when they become saturated. Replace or regenerate the desiccant as needed.
For electronic cabinets, occasionally clean the water collection tray (if present).
- Regularly Access Your Equipment:
While the dry cabinet protects your gear from moisture, you still to use your equipment regularly. Regular use helps the moving parts remain lubricated and functional.
- Avoid Overcrowding:
While it might be tempting to store all your gear in one place, avoid overcrowding the cabinet. This creates better air circulation and reduces the risk of items scratching or damaging each other.
- Additional Tips:
If you acquire new equipment or notice a significant change in the ambient humidity, you might need to adjust the cabinet’s settings.
Consider storing other moisture-sensitive items in the cabinet, such as memory cards, film, or electronic accessories.
Can A Dry Cabinet Kill Fungus?
A dry cabinet can prevent the growth of fungus on camera equipment and other sensitive items by maintaining a low-humidity environment.
A dry cabinet prevents fungal growth by maintaining low humidity. While it halts the growth of existing fungus, it doesn’t eliminate it. Infected equipment needs cleaning to remove established fungus, but the cabinet stops further growth from occurring.
There are a few things you should consider regarding fungus and dry cabinets.
A dry cabinet is primarily a preventive measure. By keeping the humidity level between 40% to 50% (or even lower for certain items), it creates an environment where fungus cannot thrive or grow.
If your equipment already has fungal growth, placing it in a dry cabinet will halt the growth but will not eliminate or remove the existing fungus.
If you discover fungus on your camera lenses or other equipment, you’ll want to clean it as soon as possible. The longer fungus remains on a lens, the higher the risk of it causing permanent damage by etching into the glass or affecting the lens coatings.
Cleaning should be done carefully, preferably by professionals or those experienced in lens cleaning, to avoid scratching or damaging the lens.
Some believe that exposing fungus-infected equipment to UV light can kill the fungus. While UV light can be effective against many microorganisms, there’s a risk of damaging the lens coatings or other parts of the equipment. If considering this method, it should be approached with caution and due diligence (research).
In addition to using a dry cabinet, desiccants like silica gel can help absorb moisture and further reduce the risk of fungal growth. However, like the dry cabinet, desiccants won’t remove existing fungus.
Even when using a dry cabinet, it’s a good practice to regularly inspect your equipment for any signs of fungal growth, especially if the equipment was previously stored in a high-humidity environment.
In conclusion, while a dry cabinet is an excellent tool for preventing fungal growth, it’s not a solution for removing or killing existing fungus. If you discover fungus on your equipment, address it promptly to prevent permanent damage.
Can I Store My Camera Batteries And Accessories In The Dry Box?
You can store camera batteries and accessories in a dry box. It provides a controlled environment, protecting them from moisture and potential corrosion. Make sure the humidity isn’t too low to avoid drying out protective lubricants on battery contacts.
I recommend regularly checking the battery health.
A dry box can be an excellent storage solution for camera batteries and accessories, offering protection from moisture-related damage.
While you can store camera batteries and accessories in a dry box, there are some considerations to keep in mind.
Lithium-ion Batteries are commonly used in cameras. While they are not particularly sensitive to humidity, storing them in a dry environment can prevent potential corrosion of the battery contacts.
If the dry box isn’t set to an extremely low humidity level, this can dry out any protective lubricants on the battery contacts.
If you’re storing batteries for an extended period, it’s recommended to store them at a partial charge, typically around 40-60%. This helps prolong the battery’s lifespan.
Batteries are sensitive to temperature. Keep the dry box away from heat sources or direct sunlight.
Memory cards can benefit from being stored in a dry environment, especially in humid climates where moisture can affect the card’s contacts. Use protective cases for added protection.
Lens Filters and Adapters
Storing lens filters, adapters, and other metal or glass accessories in a dry box can prevent potential issues like corrosion or fungal growth.
Camera Straps and Bags
If space allows, you can store camera straps in the dry box to prevent mold growth, especially if they are made of materials like leather. However, larger items like camera bags might not fit in standard dry boxes.
Flash Units and Lighting Equipment
Electronic components in flash units can benefit from dry storage. Check that batteries are removed from flash units if they’re being stored for an extended period.
Camera equipment typically benefits from a humidity level of 40-50%, but batteries and electronic accessories can be stored at slightly higher humidity levels without issues. It’s still a good idea to keep the humidity below 60% to prevent potential moisture-related problems.
Periodically check all items in the dry box, especially batteries, for any signs of swelling, leakage, or corrosion. Remove and safely dispose of any compromised batteries.
Storing Film In A Dry Cabinet
Storing film in a dry cabinet is important, especially in humid environments, to prevent damage from moisture, which can lead to color shifts, mold growth, and emulsion degradation.
Regular monitoring and proper organization within the cabinet will help maintain the quality of your film over time.
Here’s how to store film in a dry cabinet
- Choose the Right Dry Cabinet
If you’re storing both camera equipment and film, make sure the cabinet is large enough to house everything without overcrowding.
- Ideal Humidity Level for Film
Film, especially color film, is sensitive to both high and low humidity levels. The recommended relative humidity (RH) level for film storage is 30% to 50%.
Staying within this range helps prevent the film from becoming too dry and brittle while also avoiding moisture-related issues.
- Temperature Considerations
While a dry cabinet primarily controls humidity, temperature is another factor for film storage.
Ideally, store film at a cool temperature, but not so cold that condensation becomes a risk when retrieving the film. Room temperature or slightly cooler is typically suitable.
- Storing Film Rolls
Keep film in its original packaging or in airtight plastic containers to offer an additional layer of protection.
Store film rolls vertically to save space and prevent them from unspooling.
I recommend labeling each film roll or container with the film type, speed, and expiration date for easy identification later on.
- Storing Film Sheets
For sheet film, use protective sleeves or pouches to prevent scratches or damage.
Store sheets vertically and avoid stacking them too tightly.
- Avoid Mixing Different Film Types
If possible, store different film types (e.g., color, black and white, slide) in separate sections or containers within the cabinet. This helps in organization and prevents potential chemical reactions between different film types.
- Regularly Check the Dry Cabinet
Monitor the humidity level using the cabinet’s built-in hygrometer or an external one.
- Desiccant Maintenance
If the dry cabinet uses desiccants, monitor their effectiveness and replace or regenerate them as needed.
- Accessing Stored Film
When retrieving film from the dry cabinet, especially if it’s been stored at a significantly lower temperature, allow it to acclimate to room temperature before using it. This helps prevent condensation on the film.
- Expiration Dates
While many photographers use expired film for creative effects, be aware of expiration dates. Over time, even in optimal storage conditions, film can degrade, leading to color shifts and reduced sensitivity.
Can I Store My 3d Printing Filament Together With My Lenses In The Dry Cabinet?
You can store 3D printing filament and camera lenses together in a dry cabinet, as both benefit from a controlled, low-humidity environment.
The main consideration is humidity.
The ideal humidity level for storing camera lenses is between 40% to 50% to prevent fungal growth and maintain the lubrication of moving parts.
Many filaments, especially hygroscopic ones like PLA, ABS, Nylon, and PVA, absorb moisture from the air, which can degrade their printing quality. They benefit from being stored at a humidity level below 15-20%.
If you’re storing both in the same cabinet, you might want to aim for a compromise, perhaps around 30% RH. This level is low enough to protect most filaments and still safe for lenses.
How To Store Camera Without Dry Box: What Are Dry Cabinet Alternatives?
Storing your camera safely without a dry box involves taking precautions to protect it from moisture, dust, and physical damage.
While these alternatives can be effective, it’s essential to monitor the storage environment and make adjustments as needed. The primary goal is to protect sensitive items from excessive moisture, which can lead to fungal growth, corrosion, and other damage.
Here are some approaches to store your camera without a dry box:
Use silica gel packets or other desiccants to absorb moisture. Place them in your camera bag or the storage container where you keep your camera.
Remember to replace or regenerate the silica gel when it becomes saturated.
- Airtight Containers:
Use airtight plastic containers or resealable plastic bags as a storage solution. Place your camera and lenses inside, along with some desiccants, to keep moisture out.
- Avoid Damp Areas:
Don’t store your camera in basements, bathrooms, or other damp areas. Choose a cool, dry place with stable temperatures.

If you’re using a camera bag, keep it clean and free from dust. Some camera bags come with rain covers; use them even indoors to protect against dust and minor spills.
- Lens Caps and Body Caps:
Always put the lens cap and body cap on your camera and lenses when storing them. This protects against dust and minor scratches.
- Regular Use:
Using your camera regularly can help prevent fungal growth. When equipment is frequently exposed to ambient air and light, it’s less likely to develop mold or fungus.
Rice acts as a natural desiccant. You can place a bag of uncooked rice in the storage container with your camera. While not as effective as silica gel, it can help absorb some moisture.
- Climate-Controlled Storage:
If you have a lot of equipment or other sensitive items and are considering external storage, opt for a climate-controlled storage unit.
- Vacuum-Sealed Bags:
For added protection, especially if you’re storing your camera for an extended period, consider vacuum-sealing your camera.
This removes air and moisture, providing a protective environment. Just toss in a desiccant packet before sealing.
- Regular Cleaning & Maintenance:
Regularly cleaning your camera and lenses can help prevent issues. Keeping your equipment free from dust and grime reduces the risk of fungal growth.
- Cool Storage: Avoid Extreme Temperatures:
Don’t store your camera in places with extreme temperatures, such as a car’s glove compartment or trunk, as this can damage the camera’s electronics and battery.
A camera dry box and dry cabinet serve as protective sanctuaries for your photography gear.
Their primary role is to combat moisture, guaranteeing your equipment remains free from fungal growth and corrosion. Investing in such storage solutions is a testament to the value and importance you place on maintaining the integrity and longevity of your camera equipment.
While dry cabinets offer a specialized environment for safeguarding sensitive equipment, they are not the only way to guard against moisture damage.
There are numerous alternatives, ranging from household solutions to professional storage methods, that can effectively combat humidity.
With the right precautions and consistent care, you can secure the longevity and performance of your valuables, even without the use of a dry cabinet. Although a dry box is definitely helpful.
