What kind of people need a digital camera? Of course, people seeking new and seeking change, people who always have a large number of digital cameras, how to buy a digital camera that best suits you best. . .
Traditional camera VS digital camera
Whether it is a traditional camera or a digital camera, the camera is for human use, with the development of technology, so created a very smart fool camera, with the takeoff of the PC, many traditions have gradually digited, and the photography of the image is of course also No exception, for consumers, there are currently two options, what should I buy a traditional 135 negative camera or digital camera?
[Introduction to the traditional camera]
Traditional cameras are divided into single-eye cameras and double-eyed cameras, single eye is a professional who knows photography, and most of the eyes are only a fool camera. For the general consumption public, just understand the film, put the battery, press the shutter It can take the photo, as for the quality you take, just look at the quality of the camera, so the traditional fool camera is relatively simple, whether it is the old child, you can easily pick you! As for some of the professional single camera, you need to know some photography skills, and this part is not two, three pages can be said.
The traditional camera is the film, so at cost, consumers want to buy the film cost, to wash into photos, and the cost of the film and the cost of the photo paper, calculate the cost of each volume to spend approximately It is 60 yuan up and down, if it is a positive piece, about 40 yuan up and down.
[Introduction to Digital Camera]
Digital cameras are also divided into single-eye and eyes, almost the conventional cameras, but the post-treatment is more troublesome, usually need to pass through the computer. For those who have a young generation, people who don't understand the computer are less, but think about it, what is the case when this digital camera is in a grandfather, a grandmother's hand? Fortunately, digital printing progress has been possible in recent years, it is already possible to use digital image processing.
Digital camera is used by a photosensitive component, then records the image sensing in the storage medium, and the storage medium can be reused, so the user's user is taken, only the digital camera and storage media will purchase a time purchase, if It is necessary to rush into a photo. At present, 4 × 6 is about one to three yuan. Compared to the traditional negative output, the cost of each photo is similar.
[Digital advantage over traditional
Digital cameras have a lot of advantages over traditional cameras. Although the past digital cameras will be broken, they have to break two thousand, plus inconvenient memory cards, and buy it is really very painful, and one ordinary The fool camera is only more than 1,000 yuan, it feels that the traditional camera is very cheap; in fact, the cost is calculated for a long time, it is not cost-effective.
Buying digital cameras can enjoy the thrill of mad shutters, do not take good, no pain, and you can check it immediately. If you can't shoot it, you can wash it off, but the traditional camera line? Each time I press the next shutter, I spend a dollar, and I have to take a photo of the photo, but I have to wait until the photo is rushing out, if this photo is taken abroad, is it difficult to fly to the foreign country? ? In addition, digital cameras can choose their favorite photos, but the traditional camera must first wash the film first, in order to identify the one.
In addition, if you want to share photos to a friend, if a group of people travel, how much photo is to be washed, then one will be sent through different ways, how much is it? However, the numbers are different, and there is an email to pass email, and it can be received in a very fast time. If there is no, it can be sent to the photo. [Digital compared to traditional disadvantages]
Digital cameras are numbers, so in power is tight, so compared to the traditional camera, the part of the battery is relatively poor, and there is no electricity for a few hours, it is a little bit, maybe only half an hour. Optical power. The digital camera is also a pixel problem. The higher the pixels, the more fine, and the quality of the lens will also involve the imaging quality, how do you buy a digital camera?
Digital camera professional language
In the first time you buy a digital camera, there is always a big pile you don't understand, and when you purchase, pay attention to those details? Please note that the camera is used to take pictures, not used to show off, the essence of the camera is to take a photo, rather than emphasizing there, then spending a big money to buy a good camera, you may have a lifetime Don't use it or you can't use it!
[CCD VS. CMOS]
The first purchase of digital cameras will always encounter problems with the number of cameras. This is the size of the camera photosensitive assembly. The more of the increasingly photosensitive elements, the more imaging, the photosensitive components are used in addition to the size of the pixels. Different technologies will also affect image in color, contrast and brightness. At present, the photosensitive assembly has two kinds of CCD and CMOS. The so-called CCD is the abbreviation of charged coupled device. Chinese is called "charge coupling components", but the digital camera, There is another technology, that is, CMOS, he is an abbreviation of Complementary Metal-Oxide Semiconductor. The Chinese is called "Complementary Metal Oxidation Semiconductor", and the CCD and CMOS can be said to be different technologies, which is roughly, CMOS's color The contrast and brightness effect does not have a CCD. However, the D30 and D60 used by Canon are CMOS, but it is very good in the effect of imaging!
Generally, the general digital camera is used in CCD, and the CCD is divided into two types of primary color CCD and complementary color CCD.
[Primary color CCD VS. Fat color CCD]
The primary color CCD is the three primary color red green RGB of color light as a photosensitive foundation. The advantage is that the color blending accurate reduction is high, the color is relatively sharp, and the post-digital image processing is easy. However, at the disadvantage, the color step is narrow, in which black and white two colors are easily formed.
The complementary color CCD is a photosensitive foundation based on cymg. It has the advantage that the color-based color mixing changes are more and meticulous. The disadvantage is that the color is too detailed, which makes the image of the image and is not clear enough, and for later digital imaging processing is not easy, it is easy to generate dispersion or bias.
As for the primary color CCD, it is good or complementing the color CCD. This is a problem that people see people. If you see the user's needs, both have different advantages. If you just use the screen to see a photo, the digital camera that uses the original color CCD should be comparison Good consideration, because the general screen is a color performance of the color RGB mode; if the user often needs to output the file into a photo or engaged in print output, then the complementary color CCD is more appropriate. At present, most of the primary color ccd uses the Sony Suprer Had CCD, as well as the exclusive superccd of Fujifilm, where FujifiLM is a photosensitive component on the CCD in the f45 degree angle, so it feels in the pixel More, but actual pixels are not the case, so when you purchase FujiFilm's digital camera, pay attention to the actual CCD pixels, don't be cheated by the number of CCDs. In addition, different CCDs may certainly have different colors and picture quality, but even if different manufacturers use the same CCD, they will be different, because each label is in the camera internal firmware in image processing. Different technology.
[Digital camera function]
When purchasing a digital camera, in addition to the image, many functions are often headaches, digital cameras is to take the image through the lens to photoreceptor components, the length of the photosensitance is also the degree of exposure. It will affect the imaging will not be too bright or too dark; most of the digital cameras must have a fully automatic function, that is, the user will press the shutter, as for the exposure conditions, see this digital camera The design of the designer.
Some cameras will have aperture aperture, the shutter is a full manual function, and the digital camera designed for beginners has a variety of contextual models, and users can choose the appropriate situation in the environment at the time. Relaxed photo. In general, the conditions of exposure are commonly determined by the values of the aperture and shutter. The so-called aperture prerequisites are set by the user to make the camera automatically determine the shutter to set it in that value to be exposed. The shutter is right, so that the whole manual is to let the user can decide the value of the aperture and shutter. . In fact, the situation in the camera is a combination of different apertures and shutters. The camera's designer gives different values in accordance with different situations, so there will be so many situational models.
[White balance]
Another one is often plagued by the white balance. Due to the eyes of the digital camera, the human eye will automatically balance the color temperature of the surroundings, so regardless of why the color temperature is automatically corrected, the correct white, readers I can wear a colorful sunglasses try, I will look at the white thing at the beginning, but a few minutes, then look at the white, you can show the right white, this is the human eye can automatically balance, but the digital camera Different, the complexity of human eye is not the digital camera, so normal white is not white under different light, so the digital camera designer does not need to design different white balances, All digital cameras have automatic white balanced features, and a little digital camera can be handally balanced, and the user can adjust the white balance in the environment at the time.
【Memory card】
Another memory card used by the digital camera is the memory card used by the digital camera. The memory card used by digital cameras has Compact Flash (Sim), SMART Media (SM), SECURITY DISK / MULTI MEDIA CARD (SD and SD, MMC, share), MEMORY Stick (MS), MicroDrive (Micro hardware or MD) More, such as Nikon, Canon, Kodak, etc. SM is a memory card that is pushed by FujiFilm, the card is relatively thin, and very fragile. The author believes that the SM is in design. There are many problems with compatibility. At present, only 128MB, and the camera is used in Fujifilm, omlympus, etc., but these The factory is more expensive to change to other memory card.
SD / MMC size is exemplified, SD is a memory card of Panasonic's memory card than MMC. However, the price of SD is not cheap, compared with Compact Flash, which is the same specification, it takes twice the price. The MS is a memory card that is mainly pushed by Sony. At present, only the digital camera introduced in Sony; as for the size of the MD, but the CF thick, the digital camera that can use MD is a higher-order product, and Can support MD digital cameras can use CF cards. At present, MD has the maximum capacity of 1G, and 1G MD can be the fastest memory at the time of reading and storage, but MD is also a hard drive. There will be start-up time and need to pay attention to the problem of shockproof, and 1G MD is not cheap, with an average of about ten yuan.
Precautions when purchasing digital cameras
Understand the above questions, then you should ask your own demand, tell the truth, the digital camera is really a penny, but your product is not necessarily the best, because it is likely to spend a big pen. The money bought a bunch of functions that were not used. Buying a camera should pay attention to the color of the color and picture, the battery's navigation power, followed by the specification of the memory card, which is convenient and functional.
Buying the camera is not the appearance of the camera, but the color and picture quality presentation of the camera, this is the real meaning of the camera. Next, it is necessary to pay attention to the battery life, some cameras are less than half an hour. Electricity, this is really very trouble, there is a little more than half of the digital camera to use special charging lithium battery, the advantage is that the battery is more stretched, the disadvantage is that there is no electricity, and it is necessary to buy a backup battery. This dedicated charging lithium battery is of course not expensive. The memory card is of course one of the factors. Because most digital cameras are randomly attached to the memory card capacity, they can smile, so consumers will usually be added. Buy a memory card, these can be one of the costs of purchasing! As for the convenience and function of the control, it is also a very important ring. The author likes the Nikon Coolpix 5700 or Canon G2 can do 270 design, so that the user does not need to kneel down or be taken on the ground. A variety of different angles, as for functions, it is necessary to choose according to the needs of the user.
【beginner】
If the consumer is the first time to purchase a digital camera, there has never been exposed to photography or the demand for photography is not big. The purpose is just to take photos, but don't want to learn photography skills, the digital camera up and down the two thousand yuan is the most suitable. Often, this type of camera is only fully automatic and a variety of situation patterns, and it is very simple to manipulate. It will not be too high in pixels. It does not require a deep understanding, so for the elderly, children can kickle energy Press the shutter to take a good photo. At present, the camera is approximately two million images on the image. The main market is mostly the student ethnic group, so it is very avant-garde in the design, in general, two million pixel cameras, it is enough to output 4 × 6 photo. Here is a point, there are many sales in the market, and the product is not selling in the name of the digital camera. It is not good, but this type of product uses built-in memory, mostly can't expand, There are only more than one million in the image, a little better to use CCD, and some use CMOS, the lens is not very good, so the effect of the shot is unable to pass the email, and you can accept it through email. If you want to wash into a photo, you have to think twice. In addition, this class does not have LCD to look at it. If the consumer is not very demanding, the quality is not very demanding, this is a model that can be considering.
[Middle-order digital camera]
Most of the intermediate camera is more than 3,000 yuan to 4,000 yuan in the price of the first-stage camera, and the pixels are about 3 million or 4 million, which in addition to all In addition to manual functions, the aperture prerequisites are added, and the shutter is very convenient, and it is more convenient in the control. It supports the surrounding support, the user can purchase the transfer ring to turn the wide-angle mirror, remote bench or It is a filter, etc. Although two million pixel cameras have been sufficient to output a 4 × 6 photo, it is more than 4 × 6 photographed by 3 million or 4 million photos, which will be meticulous than two million pixels. Of course, It is also very enough to wash the 8 × 10 photo. The mid-order digital camera is suitable for useful users with interest in photography. After all, the digital camera can record the conditions for photographing aperture, shutter, etc., and can learn to take pictures in the file.
[High-order digital camera]
Higher order digital cameras, mostly more than 6,000 yuan, the image is about 5 million, this class of camera functions are more than the intermediate camera, more functional, can be said to be the function of electronic single-eye cameras All, only the lens is only the lens, and the high-order digital camera is suitable for the magazine plane output, and for the image, the picture quality, color has a strong demand, and this type of camera More than the surroundings, let users have more selection conditions.
[Professional Digital Camera]
Professional-grade digital cameras are digital single-eye cameras, users can replace the lens to seek the best picture quality, color and photo effect, this type of digital camera exceeds 60,000 in the image, cheap in price There are more than 10,000, there are two or 30,000, even higher, and the professional-grade digital camera is not a general human load because of the average people's load, unless there is a strong interest in photography. I believe that users who have traditional monocular cameras will dream of a such camera. At present, professional-grade digital cameras have Nikon's D1, D1X, D1H, and newly launched D100, Canon's 1D, D60, D30, FujiFilm S2 Pro, Kodak's DSC760, 460, etc.
