Ultimate Guide for digital camera

    Inadvertently, digital cameras have appeared in all areas of our lives, and increasingly accepted by the majority of consumers go use. When you walk in the street or watch major sports competitions, cultural performances, hand-held digital cameras are not difficult to find people.

However, the majority of consumers of these carefully packed new models of digital cameras, the new product is still a lack of understanding. And the purchase of a digital camera, use, maintenance involves many aspects of knowledge, for most consumers, a digital camera or a mysterious high-end products. Therefore, I will buy digital camera, use, maintenance, maintenance and other aspects of experience and knowledge to sort out to share with you, allowing you to provide a general understanding of the digital camera. To identify these knowledge, it is necessary to know how to seven points.

First, out of the high-pixel errors
    Pixels as one of the criteria to measure the quality of a digital camera, consumers are often considered to be to buy a digital camera assessment focus, many consumers and therefore into the high pixel errors, blind pursuit of high pixel, the pixels look became The only standard to measure the quality of a digital camera. Digital cameras with CCD or CMOS photosensitive, the number of pixels of the captured image depends on the number of the photosensitive element CCD or CMOS camera chip, theoretically, more photosensitive unit, and the images will be more clear. However, due to the area of ​​the photosensitive element of the digital camera is much smaller than the area of ​​traditional film, in a limited area of ​​the chip on the increase too much photosensitive unit there will be a lot of problems, such as image signal-to-noise ratio decreases sensitivity to reduce.

As we all know, digital cameras need to rely on the internal image processing engine to reduce color error. The principles of the digital camera imaging and traditional camera has a difference in the nature, the data obtained by the photosensitive element must be processed and combined to generate a final image file, and the calculation method of the processing engine directly affects the quality of the final image. Therefore, the pixels can indeed be regarded as the level of the digital camera important one of the criteria, but not the only criteria, we need a digital camera indicators to comprehensively examine the quality of the digital camera.

Second, the importance of sensor size
    There are many factors that affect the image quality of digital cameras, which, the photosensitive unit size of the digital camera sensor imaging is great. The larger the size of the photosensitive cells, the photosensitive member is more sensitive to light, the smaller the noise of the signal generated, and would be more excellent in the reproduction of highlights and shadows, and higher contrast. The photosensitive cells of the excessive increase in the limited area on the photosensitive member, will lead to the photosensitive cell is too small to bring the image SNR decreases, the sensitivity is reduced and other issues.

So, how do we know the size of the photosensitive cell? We know, is equal to the number of pixels of the digital camera image the photosensitive unit number on the CCD sensor in the camera, therefore, if the same number of pixels, the large sensor size used by digital cameras The individual size of the photosensitive cells is naturally large. Such as the pixel digital camera Canon PowerShot G2 and EOS 1D models are 4,000,000 and 4,150,000, PowerShot G2 is 1/1.8 inch CCD, the size of each photosensitive cell only 3.125 square microns, while the EOS 1D using the area of ​​28.7mm × 19.1mm large CCD, a single photosensitive cell area of ​​11.5 square microns, which is able to achieve the highest equivalent sensitivity PowerShot G2 ISO400 EOS 1D able to achieve the highest equivalent sensitivity ISO1600 reasons.

Third, the importance of the lens
    It can be said that the lens is the soul of a camera, the digital camera is certainly no exception, either an optical camera or digital camera, the lens is the most one of the elements can not be ignored.

On the surface, digital cameras due to the limited resolution of the photosensitive element, in theory, the optical resolution of the lens requirements is relatively low, but because ordinary digital camera is the CCD or CMOS sensor, the light-sensitive area of ​​its area than traditional film much smaller, so the the lens resolution requirements more stringent. Otherwise, digital cameras, even if there are a high number of pixels, the image quality is still the reason because lens and relatively poor. In other words, the analytical capacity of the optical lens digital camera must be better than the resolution of the photosensitive element.

In fact, the degree of the lens structural complexity of the digital camera and the requirements of the production process, is not lower than traditional camera lens, it is mainly by the multi-group lens, the higher the image quality, the lens is more. It is hard to say what kind of lens is the best, but with large-caliber, multi-piece group contains high-quality lens aspheric lens and high-quality coating is the best choice for users requiring perfect image quality.

Currently, the major lens manufacturers in the market, including two series, one for the Japanese manufacturers, including brands such as Nikon, Canon and Pentax; another German manufacturers, including brands such as Leica, Zeiss and Schneider. Japanese manufacturers are cost-effective, while the high quality of German manufacturers lens imaging lens, but relatively speaking, the price is also more expensive.

In addition, the digital camera lens material is divided into two types of glass and plastic, some companies have stressed that their camera lens glass material, good transmittance, the projected image is clearer. But in fact, the glass lens is not necessarily than plastic lenses clearer images, glass lens camera may also increase the weight, or should the purchase from various aspects to consider, not limited to this.

Fourth, pay attention to the details of the zoom function
    In the purchase of a digital camera, the zoom factor is generally the focus of consumers. Larger zoom digital camera more flexibility, but not simply look at the size will be able to know the digital camera shooting. Zoom the divided optical zoom and digital zoom, we first have to pay special attention to the range of the optical zoom, the smaller the minimum focal length of the camera, the greater the scope of its wide-angle shot, conducive to shooting big scenes, larger maximum focal length is far camera capability. Focal length range of 38mm ~ 114mm and 35mm ~ 105mm lens 3x zoom lens, but obviously lost the ability to shoot a big scene of 38mm to 114mm lens, 35mm ~ 105mm lens practicality necessary than the former is much higher .

In addition, traditional camera, digital camera also offers a digital zoom function, digital zoom and optical zoom intake for larger image and science fill the empty part of a lot of different digital zoom, which is the so-called interpolation Law enlarge. Need to pay attention to, the interpolation more components sacrificing picture details more, lower-definition. Therefore, the digital zoom does not have much practical significance, therefore, in the purchase of a digital camera, to focus on to look at the optical zoom range, do not listen to the merchants irresponsible propaganda, mistaking the digital zoom function can compensate The deficiencies of the optical zoom range.

5, the speed of the memory card
    Most manufacturers comes with a digital camera memory card quality is quite good, but unfortunately, these included the general capacity of the memory card are very small. Therefore, you mostly need to buy a digital camera, an additional optional large-capacity memory card, if the purchase is the memory card of the brand-name company, quality is no problem, but most of the cheap memory card, general electronic market bulk bring your cameras to buy a memory card marked or unknown products, difficult for consumers to go up to the judge the quality of the memory card from the appearance, therefore, experienced users will be able to rest assured, the actual test.

Test, you should pay special attention to test the speed of the memory card, the different quality of the product is not the same speed regardless of which memory card you use, slow memory card will make your digital camera storage takes photos more time is a very serious impact on the performance of the camera.

Simple test, you can shoot continuously fixed scene, recording the speed of the memory card. Conditional user can also use a card reader to test, but only if the speed of the reader interface to transfer data faster than the speed of the memory card to test, the best reader USB2.0 interface for testing.

Six, battery selection
    Whether using traditional film cameras or digital cameras using memory cards, batteries are very important, especially for being referred to as a digital camera for the large electricity. Some digital cameras use less than an hour will run out of battery power, if you use the LCD viewfinder, then the battery consumption faster. How to choose the camera a reliable electricity is an important issue that you need to consider the purchase of the camera, but pay attention to what your camera battery is the first thing you need to consider, figure out your camera can use the after battery types, you can begin to consider which one of these batteries is more suitable for you.

Under normal circumstances, the digital camera can be used dry batteries, alkaline manganese batteries, nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, and lithium batteries as its power. Many people used dry batteries, carbon zinc dry batteries or zinc chloride dry cell, due to the lack of energy density, is generally used for smaller power consumption of electronic products, used to drive your digital camera probably make you disappointed. While the lithium-ion battery and lithium battery technology status, performance are better, but the price is slightly higher, use more meticulous, especially lithium-ion battery, but also with the special charger.

Many digital camera users to use alkaline manganese batteries, alkaline batteries is generally said, its large capacity, the current strong and lasting use. However, the For fixed voltage digital camera, alkaline batteries appeared to be inadequate, the long-term use will make difficult for the average consumer to bear the costs. In contrast, nickel-cadmium batteries, nickel hydrogen batteries currently in battery manufacturing technology is relatively mature, it is electric high capacity, long cycle life, large depth of discharge, resistance to overcharge and over-discharge, low internal resistance and memory effect is not Obviously, the prices are more reasonable. For most users, the nickel-cadmium batteries, nickel hydrogen batteries will be a good choice, it can significantly reduce the cost of the use of digital cameras, and environmentally friendly.

7, CCD and CMOS selection of
    Traditional camera with film photosensitive principle different from the stored images, the digital camera is to use a photosensitive member to be irradiated through the lens to the chip light is converted into an electric charge, and then the electric signal into a digital signal after processing, and then after the image processing engine processing the digital signal to a certain format compression produce digital photos stored in the cache. The importance of the photosensitive element is self-evident, both CCD and CMOS digital cameras currently on the market use the photosensitive element, they are very different in function and performance, due to popular digital cameras when, CMOS technology is not very mature, so most of the consumers the idea that CCD is better than CMOS, CMOS sensor is only suitable for use in mobile phones or other occasions not so high image requirements.

In fact, this is a wrong perception. Indeed, most digital cameras use a photosensitive element CCD, This special semiconductor material through the surface of the photosensitive member to convert the light into an electric charge, can produce low-noise, high-performance imaging, it has been widely recognized and applied. But actually, the CMOS photosensitive member also has many advantages, CMOS semiconductors to convert the light, but different and CCD, CMOS each of the photosensitive member has a charge is converted to the electronic signal amplifiers, CMOS can in each pixel basis for signal amplification, this approach may save any invalid transfer operation, so only a small amount of energy consumption, while the noise is also decreased. Well-made CMOS sensor imaging results is not worse than the traditional CCD, therefore, can not be used in digital cameras to measure the quality of a CCD or CMOS sensor CMOS photosensitive element is good or bad only is the production quality and technical maturity. CMOS digital cameras produced by Canon EOS 10D is a quasi-professional-level digital camera.

Comprehensive upgrade of Fuji X100s performance of retro

Retro fashion trend is never faded, from clothing, home furnishing accessories to, this trend is still rising. In recent years in the video industry also blew up a retro theme, manufacturers get design inspiration from classic old camera shape, then the latest digital technology industry and fusion, which made us see the retro camera today, this is not the reincarnation of the play, in my opinion is a continuation of a kind of spirit.

Fuji is the industry's most keen on "retro" manufacturer, Fuji in 2010 09 month released the X100, in my impression, never seemed to have a camera like Fuji X100, in before received so much attention. About the controversy never seems to stop, the initial listing million price is too expensive, focus speed not awesome, operation menu slow reflexes... With this controversy is two years after zero seven months, we have ushered in the Fuji X100 baton -- Fuji X100s.
Fuji X100s, Fuji X100 is not much change in appearance, have unlimited power shell, presumably because Fuji X100 appearance acclaimed, drunk causes a group of young artists and pseudo literature youth, the upgrade of Fuji and no external view about change, but in terms of performance inherent Fuji, this upgrade can be very sincere!

30 times optical zoom lens full size HX100V

Compared with HX9V, HX100V is more high-end. It has 30 optical zoom equivalent focal length of 27-810mm Carle Zeiss wide-angle end, although 27mm is not a super wide angle, but general Jiao Duan was absolutely is super telephoto grade, can shoot very fine scenery distant. In addition, the flagship telephoto also many design flip screen, high level LCD specification has reached 3 inch 920000 pixel. In addition, the new machine also have manual control mode complete, lens or near a fast regulating ring, let HX100V is very suitable for the high demands of the ethnic tourism photography. In other specifications as long as the new features of HX9V have, and easy to use GPS record function, of course, HX100V is also the goods are available in all varieties.

Sony micro single NEX-5R and the main parameters

2013 for the digital imaging industry is not a good year, affected by the mobile phone, consumer DC market to shrink further, so each big manufacturer will be more focused on the SLR, mirrorless camera market, also makes the competition more intense. When it comes to no reflector digital camera, the volume is small, the quality is comparable to entry-level DSLRs types are more and more welcomed by users, the market is bigger and bigger, including Sony, Panasonic, Olympus, Canon, Nikon, Pentax, Samsung and other mainstream brands are somewhat involved, product type is rich, the threshold is reduced gradually, is many DC users to upgrade of choice.
In the absence of a reverse camera, Sony NEX series is undoubtedly the star product, after two years of development time, the whole series of more differentiation, shot number are also growing, and with the APS-C sensor relative to M4/3 quality advantage, absolute force but also become the Sony image. The position in the market, the " NEX-5 " series after C, N two products, this year also launched a new upgraded version -- NEX-5R.
As the NEX-5 series of new products, some problems for the Sony NEX-5R before is improved and enhanced. The first operational issues a criticism, new mode dial and the number of keys, plus the touch screen, more professional operation. In addition, an upgrade of the most important parts is fast hybrid automatic focusing system, greatly improves the autofocus speed, an upgrade to the content for this is also a large number of NEX users.

How to know your digital camera?

Digital cameras are popular in our daily life, a record of people life bit by bit, transient picture had no, we should record the beautiful moments, can save a little memory. Aftertaste life. A good picture of how can get good? That is completely understand your digital camera, I've come to talk with you about how to learn, how to get along well with your digital camera.

When shooting photos of people in the room, we often use a digital camera 's built-in flash to flash, but if not properly use flash light source, often leaving unsightly shadows behind the main character, serious impact on the appearance. So, how to avoid or reduce the flash shadow phenomenon?

Let people try to stay away from the walls or objects

According to the projection principle of light, when the character from the walls or behind the object is close, the original indoor lighting and natural light can not irradiation or reflected to the personalities behind walls and other objects, when the strong light flashlight, will make the figures were taken leave flash shadows behind walls and other objects. So, in does not affect the composition of the circumstances, let people try to stay away from white walls or behind the object, to maintain a certain space and distance, flash shadow will be significantly weakened.

Choose the bright background

In the indoor shooting, we can use natural sunlight bright windows and doors as background, also can use lighting lamps and other existing, as the figures were taken to create a bright background, select the appropriate shooting angle, so, flash shadow will disappear in the bright background.

The camera's position to the high number of

In the room when using the flash, the camera's position is higher, is some, like flash in projection figure below behind, will be subject to block a part, looks not so obvious, to minimize the use of head-up or look up the camera. In addition, to avoid vertical picture composition, because during the filming of vertical amplitude, the camera to rotate 90 degrees, flash in the lateral position, make it easier for flash shadow falls on the characters on one side, leaving the black shadow a character profile consistent in the background. While in the banner photo shoot, the flash light is emitted from just above the projection lens, relatively weak.

The appropriate block flash

Because of small indoor space, the use of flash shooting distance, not only easy to produce a shadow, but may also make the face white, then, we can have a shelter astigmatism with white gauze, handkerchief paper, even the appropriate block flash, flash light becomes softer. Use the gauze fabric with duct tape in the flash outside (note don't block the viewfinder and focus hole ), if a layer of soft effect is not ideal, can add two layer and three layer. However, occlusion after the flash, flash intensity can be reduced, therefore, should be appropriate to increase the exposure value.

The use of slow sync flash mode

Indoor use flash photography, in addition to the flash light source, from the door into the natural light and interior lighting will, just because of two kinds of light source is weak, cannot let the main character has enough exposure. We can use the slow sync flash mode, use flash light source to illuminate the subject character, and then use a longer shutter ( 1/15 ~ 1 ) other still shooting indoors, you can use the original indoor light flash shadow. It is best to use a three foot when shooting, also can use the tables and chairs and other objects fixed digital camera, prevent the vibration, and the figures were taken to maintain the original position until the shutter closes in the flash light after.

Using the reflected light method

To adjust the direction of the flash or can use external flash ( installed on top ) digital camera, will flash lamp toward the opposite side of the characters or ceiling, walls and other white reflector, illuminated by light reflection from the figures were taken. This reflected the flash can change the illumination direction, from the original positive light into the front light or side light, scattering light and similar natural and gentle. Using this method to avoid the use of colored surface, because it reflected light will make pictures covered by a layer of special color. The external flash lamp as far as possible from the top of the camera is placed in a higher position, the reason for this is that flash exposure of an object view is similar to the angle of the sun, so that the shadow naturally falls behind the object, without disturbing the shadow. Of course it will wreck light exposure, the need to pay attention to the accuracy of.
