Selection of digital camera

The pixel of CCD is an important index to measure the imaging quality of digital camera. Pixel size directly determines the clarity, color and smoothness of the captured image. The pixel of CCD basically determines the grade of digital camera, which is generally around 800,000 to 6,543.8+0,000 pixels, and above 6,543.8+0.2 million pixels. The area of CCD is also an important index. The image quality of CCD with small area is relatively blurred, and the color reproduction richness is also poor. The area used for anti-shake is much smaller, and the anti-shake function is of course relatively weak. In the market, Sony, Samsung and other brands have launched products with more than 654.38+0.2 million pixels. Especially noteworthy is Samsung's D93i and D99i series DV, 1/4 inch 1.33 million pixel CCD, which has clearer images and richer colors.

2. lens

Like digital cameras, the lens is also an important factor to determine the imaging quality of digital cameras. The lens must first look at the optical zoom coefficient, which refers to optical zoom. The greater the optical zoom factor, the greater the degree to which we can choose the scene size, which will bring great convenience to our composition when shooting, which is the same as the zoom lens of a camera; Second, the aperture of the lens. If the aperture is small, even the largest pixel can't shoot well in the dark, which means it will become the bottleneck of digital camera imaging. Samsung's new D 10xi and D30xi series optical zoom factor is as high as 20 times, and the lens aperture is 30mm (5mm wider than some models on the market). When you play, you can easily zoom in on distant objects and take clear photos.

3. Shape and volume

The cameras used by buyers are generally entertaining, so the appearance should be considered. The other is volume. Household cameras are generally carried with you when you go out, so it is very necessary to be small and exquisite. The most important thing is that you can take any posture when shooting, and you don't have to limit the shooting angle because of people's standing posture. Samsung's new 10 product is all reduced in price 15%-20% compared with the previous products, and its body is more compact and portable.

4. Simple and convenient operation

For ordinary consumers, simple operation is a necessary condition for choosing a machine. Samsung DV series simple Q function and concise navigation knob, so that ordinary consumers can quickly operate skillfully. The simple Q function can ensure that users can shoot the same wonderful pictures under any conditions. When using the simple Q function, the user only needs to press the simple Q key, and everything will be solved. Simple navigation button function enables you to find the most commonly used functions quickly and easily. By rotating the knob up and down, you can perform 8 functions such as manual/auto focus, shutter speed/exposure, white balance and digital stabilizer. The new Samsung digital camera series also specially designed a bilingual menu in Chinese and English, which is more convenient to operate.

Step 5 live in harmony

Wonderful pictures in life are often shared with good friends, but if the memory cards of different cameras are incompatible, they will be disappointed. That is to say, MS, MSPro, SD and MMC that are visible in the market are highly compatible, which makes it possible to transmit images and sounds between different cameras. DV player can be compatible with four kinds of cards, which is unique to some new Samsung products.

6. LCD screen

Professionals often shoot, the composition is already very familiar, and there is no need for a display screen, but most users use LCD screens when shooting. In fact, the LCD screen is nothing profound, mainly because the brightness should be high enough, the pixels should be large enough, and the larger the area, the better. The more popular ones are 2.5 inches and 3.5 inches. If you use a transparent reflective LCD screen, you can see it clearly in time in the face of the sun, and you don't have to be afraid of the black screen anymore.

Camera use skills

First, hold the camera steady.

It is best to hold the camera with both hands, which is definitely more stable than one hand, or use something that can be supported by you or prepare a camera tripod. In any case, it is to minimize the shaking of the picture. It is the most taboo way and the most easy mistake to make while walking. This shooting method is only used under special circumstances. It must be remembered that the stability of the picture is the first requirement of dynamic photography.

Second, fix the lens.

Simply put, after the lens is aimed at the target, shoot at a fixed point, instead of zooming in and out or sweeping up, down, left and right, set the screen size and start recording. Usually, the fixed lens is the main shooting mode, so as not to affect the stability of the picture. The change of the picture means changing the size and depth of field of the scene with different framing sizes or angles and positions. Simply put, when taking a panoramic view, the camera leans back a little, and when you want to take a part, the camera leans forward a little. If the position changes, such as side, high and low positions, the effect will be different. But remember not to stand at a fixed point and zoom in and out with a zoom lens, which is a common problem in many V8 families. Using more fixed lenses when shooting can increase the stability of the picture. When shooting one picture at a time, connect pictures of different sizes and make the pictures bigger and smaller with less zoom. Unless you fix them with a tripod, long-distance zooming will definitely lead to picture jitter. If you can master the above principles, your work will be more visible. Isn't the zoom lens useless to the hero when shooting? Not exactly. It's just the skill and timing.

Third, the use of manual function

Due to the different designs of various machines, the items and methods that can be manually operated are also different. Only the common skills of brightness and focal length are explained here.

1. Manual brightness level function

First of all, explain the manual brightness level function. When shooting backlight and night scene, if shooting in full automatic mode, the former must be that the subject or character is all black and the background is bright, while the latter is that the lights are blurred in the dark. The principle is not discussed here. To solve the above problems, the best way is to press the backlight correction function key when shooting backlight. If you don't have this function, switch the automatic mode to manual mode, find the brightness level key, and adjust the brightness of the picture. Brighten the brightness when backlighting and dim it at night. Usually, data will be displayed on the viewer or LCD screen in graphics or modes. Of course, the best way is to look at the picture directly on the viewer or LCD screen and adjust it to the appropriate brightness. So when you buy a video camera, be sure to let the store guide you how to use this function.

2. Manual focusing function

Usually, autofocus is mostly used for general shooting, but in special circumstances, such as barbed wire, glass, people moving between targets, etc. Often the focus of the picture will be blurred, because in the case of autofocus, the camera will judge the distance according to the signal reflected by the front object and then adjust the focal length, so this will happen. Therefore, as long as the autofocus is switched to manual and the focus is locked in a fixed position (please refer to the instruction manual for different display modes and adjustment modes of brands), the focus will not change.

Fourth, how to use the zoom lens

Cameras and cameras also have zoom lenses, but the biggest difference is that the camera can zoom while shooting and change the size of the picture. For example, if you want to shoot a distant target, you can use a zoom lens to view the scene. When you push it to the desired picture size, just press the video button and you can take the picture you want. Just like the way of fixed lens shooting. So when is the right time to use zoom when shooting? When you want to express the position of an object or a person, for example, pull a candle closer for about 3 seconds, then slowly shrink it, and the picture gradually appears as a cake filled with candles. This action makes the picture more vivid and interesting. You don't need to describe and explain. You can see what the photographer wants to say and what it means from the change of the picture. This is called "lens language". On the contrary, if you shoot with zoom, it is intended to explain a specific target or person. For example, at the beginning of the picture, a group of children are performing a panoramic dance. After a few seconds, the picture gradually approached the bust of one of the children, and then the camera followed him. This kind of shooting is like telling you that this child is my son, which is intended to guide the viewer what you are shooting. These two commonly used strokes have their own meanings, which are used properly and have the effect of making the finishing point. On the other hand, I don't know what to say, aimlessly like a headless fly, the camera is flying everywhere. Abuse of zoom lens and repeated shooting as the picture is near and far away are common taboos of many V8 families. Remember to zoom in or out, pause after each shooting, and start shooting again after changing the angle or picture. Change the way of shooting, enjoy the fun of shooting and appreciate the results of shooting.

Five, the camera dynamic shooting skills

I believe you will often encounter pictures that can't take a panoramic view of the scene. At this time, everyone must scan the camera from right to left or from left to right, which is also one of the advantages of the camera. But when many people do this action, the picture often swings from side to side or when it is fast or slow, and it looks very unsmooth. These problems mainly occur in the wrong way of body rotation, or the rotation angle is too large, which leads to hesitation and cannot be achieved overnight.

The correct way is to take the waist as the dividing point, with the lower body motionless and the upper body moving. Just like when you want to cross the road, look around to see if there is a car coming. It is reasonable to turn your head left and right below your shoulders. For example, if you want to shoot a scene, you need to scan from point A to point B. First, turn your body towards point B, then turn your upper body towards point A. At this time, the camera is facing the direction of point A, then press the video button to record for 5 seconds, and then slowly scan back to point B. After positioning, continue recording for 5 seconds, and then turn it off.

Many people will ask, how fast is the scanning speed? In fact, there is no certain standard, depending on the richness of the scenery in the range you want to scan. If you shoot a static scene, the speed can be faster, but the principle is to see the content clearly. If the framing content is dynamic and rich, the speed can be slower.

The above methods are only for reference when shooting, and the most important thing is practice and experience. Also remember to decide what to shoot before you start shooting, instead of driving the camera around looking for the target.
