Lead: What are the precautions when using a digital camera? Wonderful pictures in life are often shared with good friends, but if the memory cards of different cameras are incompatible, they will be disappointed. For ordinary consumers, simple operation is a necessary condition for choosing a machine. The following is what I introduced to you, I hope it will help you!

What are the precautions against smoke and dust when using digital cameras?

Digital cameras should work and be stored in a clean environment, which can reduce the possibility of failures caused by pollution such as dust, dirt and lampblack. Because lampblack and dust fall into the machine lens, it will affect the clarity of the camera and increase the inertia of the adjustment switch and knob. In addition, when the magnetic head and magnetic tape move at a relatively high speed, the dust falling on the magnetic head or magnetic tape will be like sand? The samples of the magnetic head and tape are damaged. In outdoor open areas, there will be more sandstorms when shooting, and there may even be strong winds. Because the sandstorm is easy to scratch the lens of the camera or penetrate into the focusing ring and other mechanical devices to cause damage, it is necessary to cover the lens with a protective cover at any time except when shooting. In areas with severe sandstorms, it is best to remember to bring the protective cover of the camera.

Anti-magnetic

Digital camera is a kind of precision equipment with photoelectric integration, and photoelectric conversion is its main working principle. Key components such as CCD and DSP chip are very sensitive to strong magnetic field and electric field, which will affect the normal performance of these advanced functional components, directly affect the shooting effect, and even cause digital cameras to fail to work. Keep the camera away from objects with magnetic lines of force, such as motors, transformers, speakers, magnets, etc. Because the camera is very sensitive to magnetic fields. Not only that, but also the radio and television antenna will distort the image taken by the camera, so it is best not to get close to it.

High temperature resistance

Digital camera adopts CCD charge coupled device, which has limited high temperature resistance, so you can't shoot directly at the sun or strong light with digital camera, otherwise it will form serious vertical smear on the image, which will affect the shooting quality. If necessary or unavoidable, try to shorten the shooting time. When the digital camera is exposed to strong light or heated for a long time, the shell will be deformed. Therefore, during use and storage, care should be taken not to expose the machine to strong light for a long time, nor to place the machine near heating pipes or electric heating equipment. Besides, don't forget the camera in the car burnt by the sun. If the camera must be exposed to the sun, please use colored sand-proof towels or shielding tools with tin foil to avoid the light.

Waterproof and moisture proof

If the digital camera is stored or operated in a humid environment, it is not only easy to cause circuit failure, but also easy to make the camera lens moldy. The video head is a wearing part and should be replaced regularly. However, the life of the video head depends not only on the material of the head, but also on the air humidity in the use environment. The greater the air humidity, the faster the video head wears. In general, when the relative humidity is 40%, the service life of the magnetic head is the longest, which can reach 1000 hours. If you accidentally spill water, coffee or drink or even fall into the water during use, we should immediately turn off the power supply, then wipe the water stains on the fuselage, then blow the rubber ball to spray the fine seams of various parts, and finally air dry for several hours, and then test whether the camera is faulty. Note: Do not start the test immediately, otherwise it may cause a short circuit in the camera circuit.

Anti-glare

Never point the camera lens at the strong sun or other strong light sources, because strong light will burn the camera tube. It is allowed to shoot the sun for a short time at the wonderful moment of sunrise and sunset, or when clouds and leaves block most of the sunshine. Don't let sunlight directly enter the viewer, because strong light will damage the viewer's screen. When lighting is used, there should be enough distance between the camera and the lamp to prevent strong light from shining directly on the camera. When you stop using the camera, you should immediately turn off the power and put it in your backpack to avoid being exposed to light.

Shock and collision prevention

Digital camera is a kind of photoelectric equipment and also a kind of precision mechanical equipment. Any vibration, especially violent vibration and collision will damage the equipment. Any electronic components and important parts that determine the imaging quality of digital cameras are damaged by vibration, which will seriously affect the operation of digital cameras. Therefore, when shooting, be sure to put your hands on the camera or camera, so as to ensure that the camera will not collide with or fall off hard objects, and it is best to put it back in the camera case or camera bag when not in use.

preservative

Digital cameras should be kept away from chemicals. When shooting in some chemical products production factories or places with a lot of smoke and dust, it should be wrapped in plastic bags and placed in a ventilated place for a period of time after use. When cleaning the camera, only dry and soft cloth can be used, or some flexible cleaning agents can be wetted with soft cloth, and solvents such as alcohol and petroleum ether cannot be used, because they will corrode the camera shell and destroy the perfection of the machine appearance.

Anti-inertia

Avoid facing the subject continuously, persistently and fixedly under strong light, especially the subject with strong contrast between light and shade, such as night light, otherwise the photosensitive target of the camera tube will stay in the position of that bright subject? Light spot? After that, it will always appear in the camera, especially the low-key pictures? Light spot? This is inertia. If this happens, you should let the camera rest for a few days, and it is generally expected to recover within one week. When the camera is not used for a long time, it should be run at least 1 time every 6 months, and powered on for 2 ~ 3 hours each time.

X-ray protection

Don't put the camera in the active area of radio waves or X-rays, because both of them will damage the lens and electronic components.

Low temperature prevention

The camera is only suitable for working at the temperature between 0℃ and 40℃. Cold protection measures should be taken when shooting in low temperature environment. We can hide the camera in our pockets and keep it at a proper temperature. We should carry a spare battery, because the camera may stop working at low temperature, which is like preheating the car in cold weather. When the machine takes a warmer room from a cold place, or when the humidity in the machine workplace exceeds a certain value, the surface of the drum will become sticky due to condensation. At this time, if the machine is turned on, the tape will stick to the drum. Due to the relatively high-speed movement between the magnetic tape and the magnetic head, it is easy to damage the magnetic head and the magnetic tape, resulting in machine failure. Therefore, it is necessary to wrap the camera with newspaper or plastic bag until the camera temperature rises to indoor temperature.
