The mold that grows in the humid environment is very harmful to the photographic equipment. Now the lens surface of the lens has a coating. This coating is very delicate. Once mildew, the mold will produce dots or filamentous mold spots on the surface of the lens, which affects the light transmission and imaging performance of the lens. In serious cases, it will cause the lens Scrapped; if the photographic equipment has been in a humid environment for a long time, its internal electronic devices will be injured, speeding up the aging of the integrated circuit, affecting the life of the display screen, etc. Therefore, in the wet spring, it is necessary to do a good job of moisture and mildew prevention for the photographic equipment.
1) Place desiccant:
The easiest and cheapest way to prevent moisture in photographic equipment is to put a few bags of desiccant in the camera bag. The desiccant can be used to help the camera remove moisture. However, it should be noted that: according to the weather conditions and the actual weather changes in the shooting location, it is often replaced, because the camera bag cannot be sealed, and the desiccant inserted does not provide continuous drying effect.
2) Sealed storage box + place desiccant:
For ordinary consumer-grade digital cameras, another more practical method of preventing moisture is to seal the storage box + desiccant. Sealed storage boxes are generally available in supermarkets, and the sealing tape at the seal of the box can effectively prevent moisture from invading. When storing photographic equipment, just put the desiccant on the bottom of the sealed box, lay a clean white cloth as an isolation layer, in principle, do not let the photographic equipment directly contact the desiccant, and then seal the box cover.
3) Moisture-proof box:
Enthusiasts who have the strength to consume, suggest to adopt a more stable moisture-proof method, that is, use a special moisture-proof box, which costs from several hundred yuan to several thousand yuan. Ordinary sealed moisture-proof boxes are mostly made of high-strength plastic or rubber. The box body is generally equipped with a hygrometer, a rubber seal ring on the lid, a pressure regulating valve on the top, and an internal moisture absorption device, such as a moisture absorption card, and The dry state can be restored by charging and heating for repeated use. The electronic dampproof box can use the dehumidifier or memory alloy to discharge the water vapor in the closed storage space to achieve the controlled humidity. In addition, to remind photographers to note that the environment of the dampproof box is not as dry as possible. The humidity suitable for storage of photographic equipment is between 40% and 50%. The humidity is too low, and the lubricant on some parts may be Dry up.
