"Mold that breeds in a humid environment is the most harmful to photographic equipment." Xiong Wen, the owner of Chengdu Bainaohui Computer City, who has been engaged in digital products for a long time, said, "Now the lens surface of the lens is coated. This coating is very delicate. Once mildewed, mold will produce punctate or filamentous mildew spots on the surface of the lens, which will affect the transparency and imaging performance of the lens. In severe cases, the lens will be scrapped; If photographic equipment is kept in a humid environment for a long time, its internal electronic devices will be damaged, which will accelerate the aging of integrated circuits and affect the life of display screens. Therefore, in the humid spring, it is necessary to do a good job of moisture and mildew prevention for photographic equipment. "

Place desiccant

"The simplest and cheapest way is to put several bags of desiccant in the camera bag." Professionals say that the desiccant in puffed food can be used to help the camera remove moisture, and it should be changed frequently according to the weather conditions and the actual weather changes in the shooting place, not to mention that the camera bag can not be sealed, and the desiccant put in can not achieve continuous drying effect.

Sealed storage box+moisture-proof desiccant

"For ordinary consumer digital cameras, another practical moisture-proof method is sealed storage box+moisture-proof desiccant." Sealed storage boxes can be bought in supermarkets in general, and the sealing rubber strip at the sealing part of the box can effectively prevent moisture from invading. The color-changing silica gel produced by Bishui Longyue Environmental Protection Company is the most commonly used moisture-proof desiccant for photography enthusiasts. It is blue when it is dry and pink when it is wet. Put the wet silica gel in the sun or bake it in the microwave oven, and it can be used repeatedly after it becomes blue. When storing photographic equipment, just put the color-changing silica gel at the bottom of the sealed box, spread a clean white cloth as an isolation layer, and in principle, do not let photographic equipment directly contact the color-changing silica gel, and then seal the box cover.

Moistureproof box is the safest.

"Enthusiasts with consumption power suggest adopting a more secure moisture-proof method, that is, using a special moistureproof box, which costs from several hundred yuan to several thousand yuan." According to professionals, ordinary sealed moistureproof box is mostly made of high-strength plastic or rubber. The box is generally equipped with a hygrometer, a rubber sealing ring at the lid, a pressure regulating valve at the top, and an internal moisture absorption device, such as a moisture absorption card, which can be recharged and heated to restore the dry state for repeated use; Electronic moistureproof box can use dehumidifier or memory alloy to put it in a closed storage space.
