How to maintain a digital camera?

Today, Mr. Minji will share with you how to maintain digital cameras! Let's talk about the fuselage first. The body of a digital camera contains a large number of integrated circuit systems, gears and transmission structures. These tiny structures are very precise and easy to get dust. Therefore, for cameras with interchangeable lenses, it is necessary to replace the lens outdoors as little as possible, and turn the body down when replacing it to prevent dust from falling into the most expensive part of the camera-CMOS sensor.

What should I do if there is dust in CMOS sensor? The most commonly used detection method is to shoot a white wall to avoid overexposure and focusing. If there are black spots on the photo (repeated many times), it means that CMOS is dusty. The safest way is to send the camera to the officially designated maintenance point and spend hundreds of dollars to clean it once. Of course, there are also some camera cleaning packages on the internet, which contain devices that can brush CMOS. For some retro cameras, the gap between the turntable and the turntable is also easy to fall off. Blow away the floating dust with a hair dryer first, and then gently wipe those stubborn stains with cotton dipped in a small amount of diluted alcohol (not too strong).

Besides, cameras in the digital age also have some focus motors inside the lens, which are also electronic devices. Cleaning the lens is mainly external, especially the glass lens. It is also a special wiping paper for blowing and lens. Wipe from the extension to the center, don't use force, it is easy to scratch the coating on the lens. Old lenses that are not commonly used are the most prone to mildew. At this time, moistureproof box must be used to safely place all camera lenses that are not commonly used. Avoid placing the battery with objects that are prone to static electricity. It is best to wrap the battery in original plastic or put it in a small plastic bag. Memory cards should avoid magnetization.

The lens can be said to be the most easily dirty place on photographic equipment, and the stains on the lens will seriously reduce the image quality, appear spots or weaken the image contrast. In the process of using the camera, it is inevitable that fingers touch the lens, and dust and fine particles will also adhere to the lens for cleaning. In fact, it is very simple: first blow off some particles with a hair dryer, and then use special lens paper or fine tools and cleaning kits to wipe off the remaining dust and fingerprints with fiber cloth. Never clean the lens with cardboard, paper towels or facial tissues.

Of course, often covering the lens with the lens cover can also prevent some lenses from touching fingers and dust. The photosensitive element of the camera should be cleaned, otherwise there will be black spots in the fixed position. When the photosensitive element is dirty, why not? It is best to take it to the after-sales or camera repair office for cleaning. Personally, it is not recommended to clean the photosensitive element manually, because the photosensitive element is fragile and easily damaged by improper operation.

The cleaning of the fuselage also needs blowing.

(1) Blow off particles attached to the fuselage by blowing. (2) Wipe the dirt with a dry cloth.

(3) Wipe off the residual stains with alcohol cloth or alcohol paper.

Whether in the south or the north, the camera lens is prone to fog in winter.

Why? The south is because the humidity is already very high. In the north, the temperature difference between indoor and outdoor is too large, or the temperature difference between indoor and outdoor vehicles is too large. In order to avoid fog, sometimes it takes half an hour or even an hour to disperse once the fog is inside the lens, which will greatly affect the capture. By the time the fog clears, the shooting opportunity will be over long ago. Therefore, for the north, whether indoors or outdoors, don't take the camera and lens out of the camera bag in a hurry, wait a few minutes and then take it out, and vice versa.

Of course, we can also put the photographic equipment in the trunk when driving, so as not to be affected by the heating of the air conditioner in the car. Before we are ready to go out, we can put the photographic equipment on the terrace and balcony and let it cool first. In order to deal with moisture, mirror cloth should be prepared. The above is the knowledge about digital cameras shared by Mr. Civil Aircraft. I hope it will help you!
