How to prevent moisture and mildew for cameras and camera lenses in the humid environment in the south?

1. If the place where you live is not very humid, you usually use a camera, and you don't need a professional moistureproof box and desiccant. Just put a few bags of desiccant in the camera bag. You can use some puffed foods that people often eat, such as the desiccant in "Want Want Snow Cake". The method is: take several bags of this desiccant and put them in the camera bag to remove moisture at any time. After a while, the desiccant bag becomes soft. According to the weather conditions and the actual weather changes in the shooting location, change several bags. Simple and practical, light and durable. But remember not to break it. If the camera can't be used normally because of humidity, you can put it under the air outlet of the air conditioner, turn on the air conditioner to the dehumidification file and blow it for about 2 hours, which may alleviate the problem. If you don't use the machine for a long time, you can also achieve the purpose of dehumidification by paying attention to energizing the machine from time to time.

2. For ordinary consumer digital cameras, it is obviously not worth the loss if you buy a professional drying box to store them, so we suggest using a sealed box with better sealing performance to store them. Sealed lockers are sold in supermarkets in all sizes, and the prices range from 10-30 yuan. We can choose the right box according to the size of the camera. But it's best to buy a box with good sealing, and there is usually a sealing tape at the sealing part. Discolored silica gel is the most commonly used moisture-proof desiccant for photographers. It is blue when it is dry and pink when it is wet. At this time, it can be exposed to the sun or dried in the microwave oven, and then it will turn blue and can be used many times. Moreover, this kind of silica gel will not emit toxic and corrosive gases, which is more suitable for camera moistureproof. General chemical stores sell color-changing silica gel, generally 10- 12 yuan can, 500g, and the price is very cheap. Put the color-changing silica gel at the bottom of the sealed box, and use a clean white cloth as an isolation layer. Just put the camera on it. In principle, do not let the digital machine directly contact the color-changing silicone. One thing to note is that before putting it into the camera, take out the battery of the camera and wipe off the dirt and sweat on the camera with a soft cloth. Finally, cover the lid, press the lid evenly to make it close, so as not to breathe.

3. The common sealing moistureproof box is made of high-strength plastic (with glue). The cover is equipped with a rubber sealing ring, and the pressure regulating valve at the top can solve the problem that the negative pressure box cover cannot be opened. Equipped with moisture absorption device (moisture absorption card), charging and heating can be used repeatedly to restore dry state. Most boxes are also equipped with hygrometers.
