In order to invest tens of thousands of photography is not willing to buy a few hundred pieces of moisture-proof box

It's not the end of the world when you wake up in the spring to find the world in a gray haze. It's a weather phenomenon called "going south," mostly in the south. Because the temperature rises, the humidity will also rise, there will be water droplets on the glass floor, sleep at night quilt is wet feeling, clothes washed for three days how also dry, usually open the dehumidifier to dehumidify the room, however, our photographic equipment is no exception, also need to dehumidify. The so-called dehumidification, that is, moisture-proof meaning, may be the north photography friends do not know the pain of the south photography friends, a lot of photographic equipment, especially the lens, the most afraid of the wet environment, do not think they buy very expensive equipment on behalf of his quality is very good, in fact, is the mistake.

Why should camera equipment be moisture-proof?

Many people spend a large sum of money to buy professional photographic equipment, but do not want to buy a few hundred pieces of moisture-proof equipment, or because they do not understand the importance of moisture-proof, when the camera is idle when the wet weather, resulting in the camera CMOS sensor and lens lens mildew case countless. This is because the lens is exposed to air, many spores will invade the lens or the internal body, attached to the lens, waiting for the wet weather, there is water began to moldy. Not only that, the camera internal circuit due to moisture and short circuit, the shutter because of rust lead to inaccurate photos exposure and so on a series of problems.

Most lens surfaces are now coated with a multilayer coating to improve lens transparency and optical imaging performance. But now the coating is composed of high polymer material, is precisely for the growth of mold provides rich nutrition environment, the mold will grow in the lens surface, hyphae experience in dendritic spread in the surface of the lens, lens of pervious to light and imaging performance, at that time, the lens is lost use value, even cleared the mold, coating on the surface of the lens will be damaged more or less, the lens will eventually be discarded. In fact, this phenomenon can be suppressed, the following is about what measures camera moisture.

Outdoor moisture-proof measures

When using the camera, pay attention to the weather, rain and humidity, or do not take out to use, unless you are the work needs, must take out to use, that is to do a good job to prevent liquid wet your photographic equipment. When shooting at the seaside, the lens must be equipped with UV mirror to prevent irreversible damage caused by sea water to the lens. After all, a UV mirror is not expensive and it is convenient to replace one.

When you take pictures outside, the weather suddenly changes and it starts to rain a little. At this time, the scene is very magnificent and there is no umbrella beside you. This time, a transparent plastic bag can help you, as long as the bottom of the transparent plastic bag opening, for the exposure of the lens, and then use the hood to jam the opening, to achieve a sealed state. This effectively prevents rain from directly wetting the lens and the body, especially the bayonet. This low-cost and readily available method, for small white easy to use, but only suitable for small rain use.

In addition to the transparent plastic bag this move, professionals need to use a special camera rain cover, the camera into the rain cover inside the use, not only can resist the rain, but also in the harsh environment can be used to a great extent to protect the camera, compared to transparent plastic bag, the safety factor of the rain cover is much higher. Of course, this will require an additional expense, the market of the ordinary camera rain cover is about 100 yuan to 300 yuan.

Iii. How to prevent moisture during storage

1. The DIY moistureproof box

If you feel oneself camera 3 or 4 thousand buy, but pass paragraph of time to play be bored with to give secondhand, buy moistureproof box to feel to have a little waste technically, occupy a place to still expend report not only. So my suggestion is to buy a sealed storage box, after cleaning with disinfectant, buy some charcoal bags or moisture-proof beads, together with the camera, you can achieve the moisture-proof effect. Still have must buy a hygrometer to put inside namely, real-time view humidity circumstance.

General camera equipment in the relative humidity value of 45%-55%RH, compromise 50%RH or so is better stored. If the relative humidity is between 20% and 30%, you don't need to prevent moisture, but you need to prevent dryness. Please check with the humidifier. In general, too much humidity in the environment will make the lens moldy, metal parts oxidation rust. In too dry environment, the lens coating will fall off, handle will open glue, its harm is no less than the lens mildew, choose the right humidity is the most important.

2. Special camera moisture-proof box

Think above that program is too troublesome, want to reach the designated position in one step, can buy camera special moistureproof box. Box above the built-in hygrometer, along with an electronic moisture absorption, can plug in the socket dehumidification by oneself, but it is important to note, please don't in cartoon electrical, electronic moisture absorption in its placed around sundry, especially for flammable and explosive items, because electronic moisture absorption cartoon electricity will produce large amounts of heat energy, more dangerous, suggested that plugged into the wall plug in.

3. Electronic moisture-proof cabinet

Professional shooting, I am afraid that a moisture-proof box can not fit so many equipment, and moisture-proof box moisture card from time to time to take out for dehumidification, not only laborious, no interval, space utilization is not large, obvious shortcomings. Electronic moistureproof cabinet is electronic type automatic dehumidification, should be inserted only report, not be afraid of to open cupboard door, should set a value only, can constant temperature constant humidity. Advanced moisture-proof cabinet will also have an anti-theft lock, that is the camera equipment safe. The larger moisture-proof cabinet has compartments, which allow us to place multiple cameras, lenses and related accessories. If you are the equipment party or tuhao, electronic moisture-proof cabinet is your best choice.

Summary: the camera is used, not put, even to put, but also to do a good job in storage. In the south, moisture-proof is a long-term job. Only when the camera is in the best condition can it be used comfortably and its service life will be greatly extended.
