How to save a digital camera when it is not in use?

Keep the camera away from dust and moisture, and take out the battery before saving it. If you don't use the digital camera for a long time, you should take out the battery, take off the leather case and store it in a box with desiccant. If possible, it should be placed in a closed space with controllable temperature and humidity. The camera is a precise machine, which is easily affected by moisture when placed in ordinary wardrobes and cabinets. Although it will not be damaged immediately, it is not a good thing in the long run. It's best to keep it in the moistureproof box. Before storage, the fingerprints and dust on the holster, fuselage and lens should be wiped clean.

Secondly, pay attention to smoke and dust prevention when using.

Digital cameras should be used and stored in a clean environment to reduce the possibility of camera failure caused by external pollution such as dust, dirt and lampblack. Because pollutants fall on the camera lens, it will pollute the lens, affect the shooting clarity, and even increase the inertia of the camera adjustment switch and knob. In the outdoor open area, the wind and sand will be relatively heavy when shooting, and there may be sudden strong winds. Because wind and sand are easy to scratch the lens of the camera or penetrate into the focusing ring and other mechanical devices to cause damage, the lens should be covered with a protective cover at any time except when shooting. In windy and dusty areas, it is best to remember to bring the protective cover of the camera.

Third, digital cameras should pay attention to preventing high temperature.

The camera cannot be directly exposed to high temperature. Don't forget the camera in the car burnt by the sun. If the camera has to bask in the sun, use colored sand-proof towels or shielding tools with tin foil to avoid the light, and don't use black tools, because black will only absorb the light and make the situation worse. When indoors, don't put the camera in a hot and humid place.

Preventing colds is also important for the use of digital cameras. Hiding the camera in your pocket can keep the camera at a suitable temperature, and you can also bring extra batteries, because the camera may stop working at low temperature, which is like preheating the car in cold weather. When the camera is brought from a cold area to a warm area, condensation often occurs, so it is necessary to wrap the camera in a newspaper or plastic bag until the camera temperature rises to the indoor temperature. In addition to condensation, taking the camera from low temperature to high temperature will also cause some compression of the camera, which is not easy for the naked eye to see, so be careful not to let the temperature of the camera suddenly change.

Waterproof and moistureproof are the most important.

However, in the actual use process, it is not excluded that there are unexpected reasons or other factors, and it is necessary to work in a humid environment. At this time, strict protective measures should be taken to ensure that the camera is not injured or less affected in this harsh environment. You can take a plastic zipper bag. In very humid or dusty climate, we can dig a small hole in the side to install the camera lens, and then put the camera in a bag to prevent fog, moisture and dust from entering the camera, which will prolong the service life of the camera. If you accidentally spray water, coffee or drinks, you should quickly turn off the power supply, then wipe the water stains on the fuselage, then spray the fine seams of various parts with a rubber blow ball, and finally air dry for several hours, and then test whether the camera is trouble-free.

Note: Do not start the test immediately, otherwise it may cause a short circuit in the camera circuit.

Lens lens is an important part of digital camera, which is often exposed to the air, so it is normal for some dust to fall on the lens. However, if you use the camera for a long time without paying attention to the maintenance of the lens, the dust on the lens will accumulate more and more, which will greatly reduce the working performance of the digital camera. For example, the dust on the lens will seriously reduce the image quality, appear spots or weaken the image contrast. In addition, in the process of use, the hand will inevitably touch the lens and leave fingerprints on the lens. These fingerprints will also reduce the effect of framing.

Clean the lens only when it is very necessary. A little dust on the lens will not affect the picture quality. When cleaning, use a soft brush and blow a balloon to remove dust. Fingerprints do great harm to the pigment coating of lenses and should be removed as soon as possible.

When not in use, it is best to cover the lens to reduce cleaning times. When cleaning the lens, first use a soft brush and balloon to remove dust particles, and then use a lens cloth to clean it. Drop a small drop of lens cleaning liquid on the wiping paper (be careful not to drop the cleaning liquid directly on the lens), wipe the lens surface repeatedly with special cotton paper, and then wipe the lens with clean cotton gauze until the lens is dry. If there is no special cleaning solution, you can breathe on the lens surface. Although the effect is not as good as that of cleaning liquid, it can also make the lens clean. Note: cotton paper must be used, and do not squeeze hard when scrubbing, because the lens surface is covered with a coating that is easy to damage.

In addition, never use hard paper, paper towels or napkins to clean the lens. These products all contain scratched wood pulp, which will seriously damage the fragile coating on the camera lens. When cleaning other parts of the camera, do not use volatile substances such as benzene and pesticides to avoid camera deformation or even dissolution.

Battery digital cameras mainly rely on batteries to provide power, but if you use mismatched batteries or don't pay attention to saving, the batteries will run out without taking a few photos. Of course, the battery will eventually run out, and when you find that it is running out, you need to replace it.

There are also many places to pay attention to when storing and carrying batteries. The newly bought rechargeable battery is generally low or dead, so it should be recharged before use. A fully charged battery is very hot and should be cooled before it is put into the camera. In order to prolong the shooting time, try not to use LCD viewfinder when shooting; Reduce the number of optical zooming; Reduce the frequency of using flash; Pay attention to the integrity of the battery insulation skin, and once it is found to be damaged, stick it with transparent tape.

Try to save battery consumption when using. First, try to avoid unnecessary zooming operations. If you really want to zoom, I suggest you move the camera position and get the same zoom effect! The second is to avoid frequent use of flash, which is a big power consumer. It is recommended that you do not use it unless absolutely necessary. Furthermore, it is best to use the viewfinder instead of the LCD screen when adjusting the image. The LCD screen consumes an amazing amount of energy, so it's best to use it less, because ordinary shooting can be done through the viewfinder. Of course, it can't be banned just to save electricity. For example, when shooting at close range, the LCD screen is an indispensable part. Finally, when you are not using the digital camera, remember to turn it off.

Most people don't pay much attention to the cleanliness of batteries. To avoid power failure, please keep the contacts at both ends of the battery and the inside of the battery cover clean. If necessary, please wipe it gently with a soft, clean dry cloth. Do not use clean or chemical solvents to clean digital cameras, batteries or chargers, such as thinner or alcoholic solvents. In addition, please clean the contact points at both ends of the battery with soft dry cloth before charging, and try to keep the contact points at both ends of the battery clean to ensure that the battery can be fully charged. If the electrode of the battery is oxidized, it needs to be wiped off. If it is seriously oxidized or falls off, it should be replaced with a new battery immediately.

The charging method also has a great influence on the battery. Using original charger and battery helps to extend battery life. For the charging time, it depends on the charger and battery used and whether the voltage is stable. If it is the first time to use the battery (or a battery that has not been used for several months), remember that the charging time of lithium battery must exceed 6 hours, and that of nickel-hydrogen battery must exceed 14 hours, otherwise the battery life will be shorter in the future. Generally speaking, it takes several charging and discharging processes to achieve the best efficiency. And when the battery still has residual power, try not to charge it repeatedly to ensure the battery life. If the nickel-cadmium battery is charged, it will stop charging after a while, and then it will not fully charge the battery. This is what we call "memory effect", which will reduce the total capacity and service life of the battery. As time goes on, the stored charge will be less and less, and the battery will be used faster and faster.

In addition, if you plan not to use the digital camera for a long time, you must take the battery out of the digital camera or charger, fully discharge it, and then store it in a dry and cool environment. Do not store the battery with ordinary metal objects. Because the battery is stored in a digital camera or charger for a long time, it may cause leakage and damage. In order to avoid short circuit of the battery, the battery should be stored with a protective cover when not in use. You should be especially careful when storing fully charged batteries. No matter what kind of battery it is, don't put it in wallets, pockets, handbags or other containers containing metal objects.
