Skills of long-term preservation of digital cameras

What are the tips for long-term storage of digital cameras? Let's have a look! ! The following are the long-term storage skills of digital cameras that I have carefully arranged for you. I hope you like them.

Long-term storage skills of digital cameras When storing the camera for a long time, the battery inside the camera must be taken out to prevent the battery from flowing and corroding the fuselage. Shutter, selfie camera, counter and reflector must be loosened before they can be reset, and cameras with built-in metering devices should also open the lens aperture to the maximum to relax the metering rod and avoid the elastic force of the tension spring dropping.

When storing cameras, we should also pay attention to moisture and mildew prevention, especially in the rainy season in the south, where the temperature is high and the humidity is high, which is easy to breed mold. Wipe off the fingerprints and dust on the holster before storage. For 135 cameras, special attention should be paid to the eyepiece, the back cover of the fuselage and the back of the holster, because the photographer's eyelashes, frame and nose will touch these places when taking pictures, leaving some oil stains. Once the temperature and humidity are right, mold will breed in these places first. Remember: the holster of the camera should be stored separately from the body and lens, because the holster (especially leather products) is more likely to absorb moisture and mold. It is best to use the oven in a humid environment, but the imported oven sold in the market, although known as? Is the outer layer (shell) strong (hard) and the middle (middle) dry (dry)? But after all, it is made of plastic and the price is very high. If you make your own drying oven, you just need to find a big biscuit iron cylinder, surround the foam plastic into a cylinder, pad the bottom, make a cover, and wrap nylon wire in the iron cylinder. A very practical oven was made by putting the color-changing silica gel particles into four small cloth bags and putting them in the interlayer between the four corners of the iron cylinder and the foam plastic. Dark blue color-changing silica gel absorbs water easily and will gradually turn pink. At this time, you need to take out the cloth bag and dry it with a hair dryer. You can also turn the lampshade of a snakeskin desk lamp or bedside lamp upside down, and pour silica gel into the lampshade to dry, so that the digital camera is clean.

Methods of digital camera protection In order to protect the lens, a colorless and transparent UV mirror or a light pink skylight (SKYLIGHT 1B) should be screwed on the lens at ordinary times. These two kinds of filter screens do not affect the exposure, which can not only prevent wind, sand, rain and snow, but also play a role in shock absorption in minor collisions.

In the cold winter, if you stay outdoors for a long time, you should always put the camera in your coat after shooting, so as not to make the battery temperature in the machine drop too low and make full use of the battery energy. When shooting from outdoor to indoor, you can put your hand on the lens cover to preheat the lens in time, so that it won't appear? Huh? What if it's blindfolded? Huh? Don't erase it in a hurry, or you'll erase all the flower lanes. Just wait a while, and the fog will disappear naturally.

It is best not to change the shutter position after the shutter of domestic mirror is tightened, otherwise it will easily cause damage. If the gear position needs to be changed, if the camera has multiple exposure devices or the shutter is not linked with the film winding device, you can cover the lens cover and press the shutter, and then tighten the shutter after adjusting the exposure time.

When changing films, the single-lens reflex camera should open the aperture to the maximum, so that when the shutter is pressed and rolled over the film head, the aperture will no longer shrink and expand, reducing unnecessary wear. Besides, you should wrap the camera strap around your wrist, so as to prevent the camera from accidentally falling, and you can hold the camera more easily, so as to avoid being too nervous in a hurry and accidentally touching the shutter curtain. In a short period of two months, a company broke the titanium curtain shutters of Nikon FE2 and Nikon FM2 continuously with its fingers, so don't be careless when changing the film.

Many books and periodicals warn photographers that direct sunlight will burn shutter curtains. However, after many tests, the author found that the possibility of curtain cloth burning is extremely small as long as it is used properly. Because the nonmetallic curtains of modern cameras are coated with heat-resistant and aging-resistant rubber coatings, when shooting outdoors, the aperture is generally in the middle and small files (such as F5.6? F 1 1), most of the light is blocked by the aperture, which greatly reduces the infrared power in sunlight. The author used a standard lens with a focal length of 50 mm, and the aperture was opened to F5.6. After five hours of continuous exposure under the strongest direct sunlight in Beijing in summer, the ordinary black fabric used in the experiment was not damaged. Although the automatic aperture of a single-lens reflex camera is always fully open, the sun will not shine on the curtains because of the blocking of the reflector. Some people worry that the sun will shine on the curtains through the gap at the edge of the mirror. In fact, in order to make the framing picture more complete, in recent years, camera manufacturers are competing to increase the area of the mirror surface, and the phenomenon that the curtain cloth is burned by light leakage at the edge of the mirror surface has been eliminated.

Please note: modern cameras are not afraid of cold sun exposure, which will cause irreparable damage to the metering system! Because whether it is gallium arsenide phosphate, blue silicon photocell or cadmium sulfide photoresistor, the sensitivity will be greatly reduced when exposed to strong light for a long time. So cover the lens cover in time after shooting.

After the camera is used, when it is put into the holster, the shooting distance of the lens must be adjusted to infinity, and then the lens barrel shrinks the shortest. Camera holster is generally divided into two parts: the back cover of the fuselage and the front cover of the lens. Take off the front cover when taking pictures, so as not to block the line of sight of the lens. When the lens is fitted with a hood, or replaced with a telephoto or zoom lens, especially with a flash, the lens front cover cannot be used. Therefore, a reasonably designed camera bag is more practical than a leather case. The camera bag should be made of impervious materials (such as artificial leather) and lighter in color (such as bright red, orange, bright yellow and white), which can effectively reflect the infrared rays in the sun and avoid the temperature in the bag from rising too high. The cushion in the bag should be made of foamed plastic wrapped with nylon thread, which is smooth, soft and lint-free. The camera with the front cover removed can be directly put into the camera bag, so that it can be taken out for shooting at any time.

Method of taking really clear photos with digital camera tripod

When it comes to clear photos, the tripod should come to mind first. A reliable tripod provides a stable platform for the camera, which can greatly improve the clarity of photos.

Tripod loading

A tripod is a good start. However, adding some weight to the tripod can make it more stable. Most tripods have a mechanism designed to hang heavy objects at the bottom of the central shaft for loading tripods. A simple way is to carry a small net bag with you, which is filled with stones and hung on a tripod. Even if the tripod has no special mechanism, it can be replaced by hanging the camera bag on the central axis.

Shutter control

Cosmetic photography, commercial photography, camera protection, photography design, model training, model company logo design, just putting the camera on a tripod does not mean that the camera is stable enough. The action of pressing the shutter will also produce vibration, which will affect the clarity of the photo. The solution is very simple, that is, use a remote shutter, and you don't need to touch the fuselage when controlling the shutter. Wired release or wireless shutter can do this.

Mirror pre-lifting

Even if the tripod has been used, the tripod has been loaded and the cable has been released, the vibration caused by the rising of the camera mirror will still affect the image quality. When the shutter speed is between 1/30s and 1s, this factor will become an important factor affecting the clarity of photos.

This problem can be solved by using the mirror pre-lift function provided by the camera. When this function is enabled, the mirror will rise when the shutter is pressed for the first time, and the shutter will be released when the shutter is pressed for the second time. At this point, the mirror vibration has been eliminated.

hole

Generally, the definition of intermediate aperture value (such as f/8) is the best. A larger aperture will soften the picture due to aberration, and a smaller aperture will soften the picture due to diffraction.

Shutter speed

Although the tripod eliminates the movement of the camera, the main body may move. Therefore, the shutter speed should be fast enough to freeze the subject. This in turn requires the use of a larger aperture to meet the exposure requirements.
