In April, spring approached with reserved steps. The earth warms up and flowers are blooming. People who have been indoors for a winter begin to like to go for an outing and travel on weekends and leisure time to get a close look at nature. Of course, I want to take pictures of myself and my family's beautiful smiling faces in this warm spring sun. In order to make your memory more perfect, here, we will teach you some maintenance knowledge of digital cameras.

First, the fuselage: soft cotton cloth to wipe

When cleaning the fuselage, you can first sweep away the floating dust attached to the surface with a soft brush, and then gently wipe the fuselage with a soft cotton cloth. Oil stains on the casing shall be cleaned with special cleaner. Dust in some gaps in the fuselage can be blown by blowing balloons at the gaps, blown out by strong airflow, or wiped by sticking strips of paper towels into the gaps.

Second, the lens: scrub carefully.

The lens is the most delicate part exposed outside the camera, and the multilayer coating on its surface is easy to scratch. Directly wiping the lens will affect the performance of the coating, so don't wipe the lens easily.

Blow off the dust stuck to the lens with a balloon first, and blow from the center of the mirror to the edge, so as not to touch the mirror. If you can't blow it off, you can gently brush it off with special lens paper or special lens pen.

If there are fingerprints and water stains, first breathe on the lens to make it moist, and then wipe it clockwise or counterclockwise with lens paper. Before wiping, make sure that there are no visible dust particles on the surface to avoid dust particles from rubbing the lens.

For indelible stains or oily stains, use special lens cleaning solution to clean them. When cleaning, use absorbent cotton balls to dip a little cleaning water solution, squeeze out the water, keep them moist, wipe the mirror in a circular motion, blow dry with a balloon after removing the stains, and then clean them with lens paper. Do not spray cleaning liquid on the lens surface.

Third, the LCD screen: cleaning, film pasting

LCD is the most easily scratched, scratched and dirty part of the exterior of digital camera. Some cameras have plexiglass protective layer on the LCD, just wipe the glass clean.

The LCD screen that is directly exposed has a special coating on its surface to enhance the display effect. It is best to use the cleaning tool or special LCD screen cleaning kit provided by the manufacturer. Blow off the dust on the surface with a balloon, and then use a liquid crystal wiping cloth or a soft wool brush to dust off the dust particles.

If there are fingerprints and oil stains, turn off the machine first, dip the cloth in liquid crystal cleaning solution, and carefully wipe it out from the center of the screen, in one direction, not back and forth, just clean it. In order to better protect LCD, we should also put a protective film on LCD. The protective film is attached in the same way as the mobile phone film.

IV. Battery: Take it out when not in use.

When the camera is not in use, you must remember to take out the battery to avoid leakage and damage to internal components after being put aside for a long time. Wipe both ends of the battery with cloth after taking it out. Nickel-hydrogen batteries should be stored in groups, and different groups of old and new batteries should not be mixed together.

Rechargeable batteries should not be stored with full charge, nor can they be stored without power. It has the phenomenon of self-discharge. It is best to put the battery in and take some photos every once in a while to observe the remaining battery capacity and charge it in time to avoid excessive discharge affecting the service life and efficiency of the battery.

V. Memory card: Keep it properly.

If you don't use it for a long time, you should take out the memory card to avoid oxidation or rust of the gold finger at the interface of the memory card due to humidity. Be sure to turn off the power supply when loading and unloading the memory card, and do not bend the memory card lightly. Don't touch the memory card directly. The human body is charged with static electricity, which may damage the interface circuit or memory chip. Therefore, it is best to use an anti-static wrist strap, or touch a metal object such as an iron pipe to generate electricity before touching the memory card. Don't put it anywhere after taking it out. It's best to put it in the original protective box, away from high temperature, high humidity and strong magnetic field.

Six, storage: moisture and mildew.

The camera should be kept damp-proof and mildew-proof. Humidity will breed mold in optical components such as the lens, which will affect the light transmission and imaging performance of the lens. When storing, take out the battery, remove the holster, lock the lens aperture at the maximum position and set the focal length at infinity, and then put it in a breathable and shockproof camera bag, which should be filled with Bi Shui Long Yue desiccant or strong mildew inhibitor. Or make several small bags with cloth with good air permeability, and put them in a sealed glass or plastic container with the camera. The humidity in the box is controlled between 45% and 55%. Too dry will dry up the lubrication of the fuselage and crack the bonding part.
