Cameras don't need to be kept for a long time.

In many people's minds, the camera is a delicate and fragile product, which needs to be handled with care to avoid bumping. However, it is not clear how to deal with specific problems after they occur. So, today I compiled a set of camera maintenance strategies for your convenience. I hope your love machine can serve you better in a longer time. Common sense of digital camera maintenance How to keep a camera for a long time?

Camera is a precision instrument, which has certain requirements for shockproof, dustproof and waterproof. When we use and store cameras at ordinary times, how to avoid the above situation and how to deal with it after it happens, there are some matters needing attention when dealing with it. These small series will explain them to you in the following articles.

First, the camera's shockproof and countermeasures

1. Shockproof of camera and its countermeasures

The most common man-made faults of cameras are mostly caused by falling, bumping and squeezing of cameras. As a high-precision electro-optical instrument, the position of its internal components and lens must be kept very accurate. Any dislocation and damage will cause unpredictable damage to the camera. Needless to say, even violent vibration may cause invisible "internal injuries", and the LCD screen is also pressed everywhere.

These damaged cameras even upset Bian Xiao. Random placement and bad habits will take away your precious "life" at any time. Then how should we protect the camera from such "persecution"? Don't worry, please read on and I will tell you one by one.

Step 2 stay away from danger and bad habits

Some friends think it is troublesome to put the camera in the camera bag when taking pictures, so they simply take the camera in their hands and take pictures with them. This is understandable, but you should pay attention at this time, because many times the camera is accidentally thrown out like this. Small card machines are generally equipped with hand ropes, and it is a good idea to wrap the hand ropes around your wrists. For large cameras, it is best to hang the standard sling around the neck, which can effectively prevent the camera from accidentally falling. At this time, don't hold the camera in your hand, let it "sway" around your neck and bump into hard objects around you. Try to wear clothes with few metal ornaments on the upper body to avoid scratching the lens and LCD screen, even if the shell is scratched by spray paint.

You are also very particular when you place your camera. Try to stay away from tables, sofas and dangerous goods. Generally, the camera strap of a SLR camera is relatively long, and when the camera is placed on the table, it often hangs down on the table, so as long as pedestrians pass by, it is likely to "bring" the camera down. Also, the removed lens must be placed vertically, otherwise it is likely to roll to the ground while you are not paying attention. Sofas and chairs are the "hardest hit areas" where cameras are damaged, and card machines with broken LCD screens can always be seen in maintenance stations. In addition, children can be said to be natural killers of cameras, and it is not impossible to pick up the camera and throw it away driven by curiosity. I won't say much about this.

Keep away from the table when placing, and don't hang down the straps.

Stay away from all dangerous goods.

3, safe and reliable camera bag

The appearance of camera bags has undoubtedly saved many cameras. A good camera bag is not only as simple as putting the camera and its accessories in, but its core function is to protect your camera more comprehensively. At present, there are a large number of camera bags on the market, and consumers' choices are very rich. Bian Xiao's suggestion is to buy camera bags of well-known brands as much as possible, so as to ensure camera safety and user comfort.

The picture shows the camera bag.

4. A beautiful and practical camera bag

Photographic bags of various styles

For card cameras, it is the first choice for many people to equip a camera bag with fashionable appearance and beautiful colors. Generally speaking, this kind of camera bag is attached randomly, which is convenient for the storage of the camera, has the function of protecting the camera and is very practical.

Second, the camera dustproof and countermeasures

1, camera dustproof and countermeasures

The most troublesome thing to say is that everyone who plays with the camera knows that it is dust. Once the dust enters the lens, it is a very painful thing. Dust sticks to the lens and cannot be removed. Every photo taken has flaws. Ordinary people dare not easily take off the lens to remove dust. That feeling is quite painful. Even if there is no dust on the lens, it is inevitable that the lens will be stained with all kinds of dirt. Therefore, dust prevention is also very important for cameras.

Telescopic lenses are prone to dust.

It has been used for a long time, and dust is stuck everywhere.

2. Actively clean the camera

As the saying goes, "You often walk by the river, how can you not wet your shoes"? Frequent use of the camera for a long time will inevitably get some dust, and the lens will also get all kinds of dirt, and the "sanitary dead angle" between the eyepiece, shutter and mode dial of the optical viewfinder and between the lens ring and lens frame is also very easy to accumulate dust. Next, we will take the initiative to clean the camera. When it comes to cleaning cameras, the four-in-one cleaning kit is the first one. A typical four-in-one suit includes a brush, a hair dryer, a mirror cleaning cloth and a bottle of cleaning liquid, which is simple and cheap to use. Blowing can blow off a small amount of foreign matter and dust (never blow with your mouth, blowing out spittle stars will ask for trouble). When there is much dust, it's the brush's turn to play. The material of the brush is soft and does not hurt the lens. It is especially suitable for cleaning the dust on the mirror frame, and the effect is better with blowing.

Four-piece cleaning kit

Wipe the lens with a neutral cleaning solution.

For some stains on the lens, we can gently wipe them with a mirror cloth. If the stain is stubborn, it should be accompanied by a small amount of night cleaning. First of all, we will spray a proper amount of cleaning liquid on the mirror cloth, and then wipe it on the lens from the inside out, which can remove stubborn stains well. When cleaning the camera, you must pay attention. If it can be removed by blowing and brushing, try not to wipe it, because in the process of wiping, you may scratch the lens because the cloth is not clean. Just find a soft cloth or a corner of a coat like glasses. I never got rid of the habit of rubbing hard. But some oil stains or stubborn stains and fingerprints really need to be wiped. Be sure to use neutral cleaning solution of assured brand and avoid using highly corrosive chemical solvents. Moreover, the cleaning solution cannot be sprayed directly on the lens to avoid leakage. Mirror cleaning cloth should be cleaned regularly, and replaced regularly if possible. In addition, UV mirror is also a thing that can effectively avoid the lens from sticking to dust, which is convenient to use and inexpensive, and also has a certain protective effect on the lens.

3. Don't let the camera bag become a sanitary corner.

As a professional camera bag, try not to put other items, such as snacks and clothes. Because after placing food, it is inevitable to spill some food fragments, which are not easy to be found, and these fragments are likely to run into the camera lens, and you will regret it when you find it. So we'd better clean the camera bag regularly and don't let it become a sanitary corner.

Three, the camera waterproof and countermeasures

1, camera waterproofing and countermeasures

As an electronic product, water is undoubtedly its biggest nightmare. Water will not only completely destroy an electronic device, but also the problems of humidity and mildew are not optimistic. If your camera is not a three-proof model, you'd better not use a protective cover and stay away from the beach, rain and snow, especially when it rains heavily in Beijing. Is your camera well protected?

Conditional friends can choose this fully enclosed waterproof sleeve, but in most cases, we just need to prevent rain from dripping in our daily life. What should I do if I want to take a rain scene occasionally but I am afraid that the camera will get into the water? Let me show you Bian Xiao's rainproof tricks!

2, understand the video network Bian Xiao waterproof trick! Plastic wrap!

Yes, you are right. It's plastic wrap. Every household has it, which is an important prop for us to protect the camera from water. The following is a demonstration of how to protect the camera with plastic wrap.

The preparation work is very simple, plastic wrap, hood, UV mirror.

Start with the lens bag.

Pay attention to the details: the roots should be tightly wrapped.

Pack more plastic wrap.

That's about it.

The lens is partially wrapped.

Plus the range hood, the sealing is better.

Cut off the extra parts.

Be careful not to hurt the lens with scissors.

Cut it like this, and it's almost ready.

Coupled with the UV mirror, the lens is not afraid of water splashing.

The appearance of completion

In order to strengthen waterproof, we wrapped another layer.

Completely sealed

Cut off the plastic wrap in front as usual.

Start the fuselage section

Please wrap the dial loosely for easy operation.

Just wrap it three times.

There are also packages on the LCD screen.

That's it.

The effect is not bad, and it is not a problem to prevent a light rain.

There is nothing wrong with the operation.

The lens can also be effectively waterproof.

Does not affect the screen display and framing.

This waterproof method of plastic wrap is no problem to deal with some light rain. The plastic wrap does not affect the operation, and has good waterproof performance and low cost. Everyone can do it. But what if the camera still accidentally gets into the water? How to deal with it? Don't worry, Bian Xiao has summarized the first aid manual for camera flooding for you.

Four, the camera in the water first aid manual

What should I do if the camera accidentally gets into the water? If the camera confirms that there is water, no matter what kind of liquid it is, unplug the battery immediately, remember! Don't press any button during this time, even if the camera is on (otherwise water can easily enter the fuselage) to prevent the circuit from burning. If the camera is splashed by fresh water (mineral water or tap water), it can be placed in a dry and ventilated place for at least one day, or it can be placed under a micro-heat source such as a desk lamp or an incandescent lamp to let the water disperse slowly. This process takes more than eight to ten hours. Don't use a strong heat source such as a hair dryer to get close to the camera, which will lead to serious aging of the line and even deformation of the shell and circuit board. It is generally not a big problem to conduct functional inspection after electrifying. If the camera enters juice, cola or the whole machine is seriously flooded, it should be sent to the maintenance station immediately for treatment. There is nothing to hesitate about. Time is the life of your camera. Because drinks have a strong corrosive effect on the circuit board of the camera and the metal parts in the camera, if not handled in time, the consequences of the camera will be very pessimistic. If it is serious, the camera will be scrapped, even if it costs money.

If the camera is flooded, it will be miserable.

It is suggested that friends with conditions at home can prepare a drying oven, especially in the humid areas in the south. After using the camera in rainy season, more or less some moisture will enter the camera. Putting a camera in a drying oven usually helps to remove moisture from the camera. It doesn't matter if there is no drying oven. We can make one ourselves. Usually, there are desiccants in food packaging, so we will collect those desiccants. Of course, the more the better. Then we find a sealed box and put the desiccant in it, so a simple drying oven is ready.

How to protect verbs (abbreviation of verb) under extreme conditions

For the majority of photographers, it is inevitable to encounter various extreme weather conditions when traveling abroad. How to protect your own equipment in all kinds of extreme weather, and avoid equipment acclimatization or even strike? Bian Xiao gave some suggestions here.

2. Very hot

In desert areas or in the case of sun exposure, the temperature can rise to a very high level. This will seriously affect the performance of electronic equipment, especially CCD/CMOS photosensitive elements, and will also destroy the performance of batteries. So please try not to expose your equipment directly to the sun, and put it in a light-colored camera bag, which can reflect sunlight and emit heat. If driving in high temperature, it is best to put the camera in a cool place to avoid direct sunlight.

Cold environment

3. Great cold

At very low temperature, the efficiency of the battery will decrease and the mechanical shutter may freeze. To prevent this failure, please put the camera close to your body, for example, under your coat. Take it out when necessary. Keep it warm with your body temperature, except for a short time. In addition, put the spare battery in your shirt pocket and let it benefit from your body's heat. If the battery in the camera is broken, you can replace it with a warm new battery.

In particular, if a cold camera is brought into a hot room, the condensation of moisture will become a problem. The lens will be like a glass filled with ice water in hot summer, and the surface will be covered with water vapor because of warm air. However, this is not the most deadly. If there are condensed water droplets on CCD/CMOS, the consequences will be very serious. To avoid this, the camera should be warmed up slowly. Put it on a cold windowsill or corridor for a period of time, gradually reach the indoor temperature, and then bring it indoors.

Dust environment

4. Dust

Bian Xiao's advice is that it is best not to open it when you encounter dusty weather during your trip. Because many SLR lenses and some telephoto card camera lenses are telescopic, once sand enters the telescopic part, it is very dangerous, and the possibility that the lens cannot be telescopic or even damage the lens driving motor is greatly increased. So be sure to pay attention when using it. If you have to use a camera, you can use the plastic wrap waterproof method mentioned above to prevent dust from entering.

Matters needing attention when using camera with intransitive verbs

(1) Try not to direct sunlight.

Try not to direct sunlight or strong light when using digital cameras. Although SLR cameras only press the shutter for exposure, strong light has little effect on the sensor. But staring at strong light for a long time is likely to damage the camera's metering system. The optical path of the card camera is facing the light source, and the sensor has been working. Facing the sun for a long time will cause the aging of the sensor, so try not to shoot the sun, especially the scorching sun at noon.

(2) The card camera turns on "hibernation" and retracts the lens.

For the card machine with retractable lens, the retractable lens is very fragile. It is suggested to turn on the "sleep" function of the camera, let the lens retract automatically after a period of inactivity, close the self-contained lens cover to prevent the lens from being damaged and deformed due to unintentional collision, and touch the shutter to return to the shooting state.

The telescopic lens of the card machine is very fragile.

(3) Don't often unscrew the lens from the fuselage outdoors.

Don't often unscrew the lens from the fuselage outdoors, it is inevitable that dust will enter outdoors. When replacing the lens, it should be carried out as far as possible in the case of less indoor dust. You can't change the lens after sweeping the floor or folding the quilt.

It's easy to get dust when changing lenses.

If you can pay attention to the above details when using the camera, it will make your camera healthier.

Seven, memory card maintenance and maintenance

For digital photography, memory card plays a very important role in the process of photography. However, due to the simple use of memory cards, memory cards are often damaged due to careless use and handling by users.

The first principle of protecting the memory card is to always install and remove the memory card only when the digital camera is turned off. The common mistake of users is to take the memory card out of the camera in a hurry, without paying attention to whether the camera is completely turned off, especially for SLR users. Many times, the camera is just in standby state, and it is not really turned off. This is likely to lead to memory card damage and reading errors.

Pictured: various memory cards

Secondly, don't format the memory card at will. It's best to use the format in the camera first. When using the camera to format the memory card, pay attention to whether the camera has enough power. When using a computer to format a memory card, pay attention to choosing an accurate format. At the same time, you need to pay attention to avoid using and storing the memory card in high temperature and high humidity environment, and don't put the memory card in high temperature and direct sunlight. Avoid physical injuries such as heavy pressure, bending, falling and impact, and stay away from static electricity, magnetic fields, liquids and corrosive substances. When taking out the memory card, please avoid touching the storage medium of the memory card. If the contact point of the memory card slot becomes dirty after long-term use, which makes it impossible to store and read information, you can blow it with compressed air and never wipe it with a small stick, otherwise it may cause more problems.

Eight, how to store the camera for a long time?

If we decide not to use the camera for a long time, we must first fully charge the battery, which is not only good for the battery, but also convenient for us to use it directly next time. Then thoroughly clean the fuselage with the method mentioned above to ensure the cleanliness of the fuselage. Then there is the problem of moistureproof. It is best to put the camera and battery in the moistureproof box, so as not to get wet. After the camera is damp, it will grow mildew on the fuselage and lens, which will affect the use of the camera, and the serious one will be scrapped!

It can be effectively moisture-proof in moistureproof box.
