How to keep the camera when it is not in use?

How to maintain a digital camera

Digital camera is a kind of precision instrument, which is not as durable as traditional camera. Some users will put their digital cameras in closed cars in the sun. High temperature will not only deform the plastic shell, but also shorten the service life of digital cameras. In addition, protective measures should be taken when it rains, because digital cameras are not ordinary traditional cameras, and once the circuit board penetrates too much rain, it will cause a short circuit.

1 On the LCD screen,

The most common thing is that it will be stained with fingerprints or some grease and dust, which looks very disgraceful. Generally, it can be wiped with fine glasses cloth or magic cloth produced by "3M" company. Remember to wipe it gently, and be careful not to use strong glass cleaner, because some digital cameras have anti-glare films on the LCD surface. Once the film is damaged, it can't be repaired, which is not covered by the warranty. In addition, you can also buy and use a screen protector. Just take it back and cut it into a suitable size and stick it on the LCD screen to prevent the LCD screen from being scratched.

2. Maintenance of the lens

After the camera is used, the lens will be stained with dust more or less, and the dust on the lens will cause the development quality of the photo, so the maintenance of the lens is very important. Generally, the dust on the mirror surface is removed by blowing the ball first. If you skip this step and wipe directly on the mirror, it is equivalent to polishing the lens with sand, which directly leads to mirror damage. Then wipe the cloth with a special lens and gently wipe the stain from the center to the outside; If you want to use special cleaning liquid for lens, please stick it on the mirror cloth first and then wipe it on the lens, but you can't drop it on the lens casually.

3. Moisture and mildew prevention

For ordinary users, when buying a digital camera, they may have to buy a simple sealed moisture-proof box and desiccant. Small moistureproof boxes are around 250 yuan, and medium-sized 450 yuan has enough space to store consumer-grade digital cameras, memory cards and future CDs. Consumers who want to do it once and for all might as well buy an electronic moistureproof box for storage and strictly control the temperature and humidity.

4. Use of storage media

Of course, memory cards are not permanently indestructible. At present, although the memory cards on the market are thin and short, they are not indestructible and cannot withstand actions such as pulling out or folding. In addition, some users often make the mistake of taking the memory card out of the camera or turning it off directly. In fact, many times, memory cards are stored. At this point, the file being stored may be destroyed or the memory card may be permanently damaged.

5. Use of movable joints

Digital camera is a high-tech electronic precision product. Don't expect it to maintain the highest quality operation after landing. In particular, digital cameras currently require functions such as rotatable lens or LCD screen. Remember that it is convenient to shoot, but also be careful to operate and use it well, otherwise once it is destroyed, the whole camera will not work.

6. Maintenance of rechargeable batteries

Different from traditional cameras, digital cameras have a great demand for electricity. Generally, they can use the upper and lower limits of 70~ 120 minutes. Ni-MH and lithium rechargeable batteries have their own skills. Ni-MH rechargeable battery has memory effect. Try to use up the battery before recharging. Generally, it can be recharged for about 300~500 times. If it is a special lithium battery for general digital cameras, the battery will age after charging for hundreds of times. It is recommended to buy an extra battery at the beginning of the purchase, otherwise the parts of the camera model at that time may not be found after three to five years. Also, when the camera may not be used for more than one month, the battery must be taken out and stored in another place to avoid unnecessary damage to the machine, which is especially important for using non-rechargeable batteries!
