How to maintain the camera

First, cultivate safety awareness and resist bad habits.

The human failures of digital cameras are mostly concentrated in bumping, squeezing and water ingress. As a precise electronic optical instrument, many times, whether it is a petite card machine or a professional machine that looks very powerful, it is actually very fragile. Needless to say, even violent vibration may cause invisible "internal injuries" and crush LCD screens everywhere.

It is safe to put the digital camera in your bag and lock it in the cupboard, but you always have to take it out for use. There is no need to emphasize the significance of grasping the camera, not only for taking pictures clearly, but also for preventing the camera from being accidentally broken. Small digital cameras provide a hand rope, so don't be afraid of the trouble of winding it around your wrist, because this kind of miniature camera with small size and smooth appearance is the easiest to get rid of. Large cameras usually have a belt fixed at two points and should be hung around your neck. At this time, don't hold the camera in your hand, let it "sway" around your neck and bump into hard objects around you. If possible, you should wear a professional photographic vest or a coat with few metal ornaments to avoid scratching the lens and LCD screen, even if the shell is scratched by spray paint.

After the shooting, the camera placement is also very particular. Some friends think it is troublesome to put it in the camera bag and take it out, so they just put it naked for a short time. This can't be absolutely forbidden, but pay attention to the location. First of all, stay away from dangerous goods or heavy objects or metals that may cause harm to them. Fish tanks, washbasins and other water containers should be avoided. In the new year's film "Bonzi Tiger Chicken" just staged, the hero watched the cordless phone used to save lives fall into the fish tank, and the expression that he wanted to cry was sad. Don't try to test the waterproof of the camera. In addition, sofas and chairs are also the "hardest hit areas" where cameras are damaged. Card machines with broken LCD screens can always be seen in the maintenance station. Generally speaking, don't put the camera on the top of the cabinet or on the edge of the table. These places are easy to be accidentally touched by yourself or your passing family and colleagues, unless you are already planning to expect your colleagues to break it and spend money to buy a new one. Don't put the camera where children can reach it. This common sense is not much to say.

There are also potential dangers when connecting a computer to transmit pictures, mainly from the location of the camera. Don't mess up the data line. Tripping and scratching will not only hurt people, but also cause the camera to break. Some careless people's desks and workstations are often like garbage dumps, which are not suitable for cameras to "survive". At this time, it is recommended to use a card reader to transmit data, and it is best to put the camera in the bag honestly after use. In addition, when using the camera, you should pay attention to drinking moderately, and it will be lively if you knock over a cup of coffee or coke.

Second, shooting precautions, get out of the misunderstanding

The former mainly introduces the possible bad habits of camera placement and holding. In fact, there are also many "small moves" that should be avoided during use.

Some users use cameras because they have no concerns about the number of films, so they are used to "shooting". This is not only not conducive to self-cultivation, improve photography level, but also has an impact on camera life. Frequent exposure is also a test for cameras. If there are more than 20 thousand cameras for civilian use, few of them break down. This is not just a shutter problem, but the aging of the overall circuit and flash capacitor. We don't have to give up eating because of choking, but we should also avoid unnecessary waste. Sometimes photography is like shooting a gun. The short guns fired by veterans are steady and unrelenting, and the bullets fired by militia and novices are aimless.

It shouldn't take too long for the camera to record short films. After all, it is not a professional camera, and its practical value is not discussed for the time being. The principle of camera progressive scanning CCD is different from that of camera interlaced scanning. Recording images for a long time makes CCD run continuously at high power, generating amazing heat and damaging its life. In addition, precautions are also mentioned in the camera manual. Don't aim the camera at highlights or the sun, which may damage the CCD, or may display purple vertical stripes or diffracted light on the LCD screen, leading to misjudgment failure.

It is not recommended to switch the camera power frequently in order to "save power" during standby. Key switch products are better, such as Canon and Panasonic, and horizontal push-pull toggle switches are often used extensively in cameras, with a high failure rate and materials that are particularly prone to fatigue and aging. It is suggested to turn on the "sleep mode" so that the lens can be retracted, the self-contained lens cover is closed to avoid damage and deformation caused by the collision outside the lens, and the shutter is touched to return to the shooting state.

If the camera doesn't touch the screen, it's best not to point with your fingers, and the lens surface can't be touched. There is no denying that many people have such bad habits when they look at the handprints on the computer screen. After buying a camera, you'd better stick a film on the LCD screen. Pay attention to choose a special film with good light transmission and small discoloration, otherwise the image will judge the color temperature of the photo. Film pasting is mainly to prevent scratching, especially for models with LCD screen without protective cover. As for the lens, if possible, it's best to add a coated UV filter, not to prevent the ultraviolet rays that the camera doesn't care about, but to avoid dust and physical damage. Besides, you'd better look at your hands. If you want to operate the camera, don't leave scary long nails.

Attention should also be paid to the maintenance of the battery box memory card used in the camera. The service life of rechargeable batteries is often less than two years, so you should be prepared for it. In case of automatic shutdown, non-startup, etc., the battery must be checked first. In addition, the use of memory cards should be specific, and it is best not to change them frequently. This seems to conflict with the use of card readers, but in fact, it's okay not to change common cards often. Because the metal contact of the card slot will be shaped after long-term use, and there are individual differences in individual card types, or the thickness and contact position of SD card and MMC card are often different, the result of frequent mixing is the physical damage of the camera card. This is not alarmist, there is no precedent.

Third, water vapor, dust, the enemy of the camera

Water will not only completely destroy an electronic device, but also the problems of humidity and mildew are not optimistic. If the camera is not a three-proof model, it is best to stay away from the beach, rain and snow without using protective covers. The rainy season in the south is humid, so you should pay attention to the safety of unused cameras. There is a big temperature difference between indoor and outdoor in winter in the north, so don't turn on the camera when you go out to take pictures, so as to avoid the phenomenon of "frost return". If the camera is short-circuited by water, it is likely to burn the chip, and it is also easy to cause pin corrosion of the chip when it is wet. The famous "shutter" phenomenon is caused by CCD being damp. Moldy, on the other hand, can easily leave spots inside the lens that cannot be scrubbed clean, and even corrode the coating to affect imaging.

In addition to passively avoiding unfavorable environment, we should also pay attention to the skills of carrying and using cameras. A shockproof and waterproof camera bag is a must for enthusiasts. Although it may not be a famous brand that pursues high prices, we should also consider using strength to choose a higher level of protection. Even if it is used at low intensity or carried in a bigger backpack, you should refer to walkman's habit and buy a soft inner bag to wrap the camera.

Once the camera is not used for a long time, the battery should be taken out and placed. However, it should be powered on once a month as far as possible to avoid the circuit being damp or the battery failing for a long time. Professional drying oven is a good choice for storing cameras and lenses, but the price is relatively high, which is also a waste for general household use. It is generally believed that the self-made simple moistureproof box is made of plastic sorting box and desiccant. Desiccant is easy to find. They exist in the packaging of puffed food and dried seaweed. Eating a few packs of snacks can accumulate enough desiccant. If you are too lazy to prepare a simple drying oven, at least put some bags of desiccant in the camera bag.

Fourth, actively clean the camera.

Whether we pay attention to the use environment of the camera or develop good operating habits, we are passively reducing the probability of damage and fatigue of the camera in use. As the saying goes, "if you walk by the river, how can you not wet your shoes?" Every time you use the camera, you will inevitably get some dust. If the camera body and lens are not well sealed, it will also cause dust. The surface of the lens and the outer layer of the screen will inevitably be contaminated with all kinds of dirt, and the "sanitary dead angle" of the optical viewfinder eyepiece, shutter and mode disk, lens ring and lens frame is also very easy to accumulate dust.

Developing good hygiene habits is a sign of being responsible for the camera. With the development of science and technology, the problem of cleaning digital cameras becomes easier. The traditional lens paper is believed that most novices can't use it well, and the effect of cleaning stubborn stains is not very optimistic. At present, many accessory brands have launched cleaning kits for digital cameras, ranging from two-in-one and three-in-one to four-in-one. To buy a cleaning suit, you should not only choose a reliable brand, but also find out the tools you need.

This is a typical four-in-one cleaning suit, including brush, hair dryer, mirror cloth and cleaning liquid. Brush and air blowing have been used for half a century, and I believe that friends who are familiar with photography have experience in using them. Blowing can blow out foreign particles and dead corner dust well, but some electrostatic dust can't be blown out, which requires the cooperation of brush. The material of the brush is soft and does not hurt the lens. It is especially suitable for cleaning the dust on the mirror frame, and the effect is better with blowing.

You must pay attention to cleaning the camera. If you can clean it with a hair dryer and a brush, try not to wipe it, because in the process of wiping, you may scratch the lens because the cloth is not clean. Just find a soft cloth or a corner of a coat like wiping glasses. I never got rid of the habit of rubbing hard. But some oil stains or stubborn stains and fingerprints really need to be wiped. Please be sure to use neutral cleaning solution of assured brand and avoid using highly corrosive chemical solvents. When in use, spray a small amount of cleaning liquid on the mirror cleaning cloth, and then gently wipe it from the inside out after it is completely soaked. Can not be sprayed directly on the lens to avoid leakage. Also pay attention to the sanitary condition of the mirror cleaning cloth itself, and replace it regularly if possible.

abstract

Developing good habits can avoid accidental injury to the camera and waste the life of consumable parts as much as possible. Scientific storage and cleaning can ensure the safety and cleanliness of cameras. Two-pronged approach, basically there will not be too many accidents. Although the speed of camera elimination has also become very fast in recent years, at least it can ensure that the camera can give full play to its performance in the process of use and sell at a good price when it is used.
