Because SLR camera features a powerful, easy for ordinary people overlook some of his camera and also has great features, it is the filter pattern. We often see the card machines have a rich filter style, whether you are willing to experience the SLR 60d camera filter function so special about it with Canon 60D Battery Grip?

Canon EOS 60d

Canon EOS 60d

When we finished shooting the Canon 60D a picture, press the playback button on the camera screen you can just play back photos, at this time we only need to press the Q button on the camera, you can be one of the photos series of stylized settings as SONY NEX-7 battery. As we enter the Canon 60D photo settings can be found in the left side of the screen are arranged in a variety of options to protect the image, rotate, scoring a series of creative filters and other functions, first we need to move the arrow keys to select our need creative filter function.

Filter function in the creative, we can see the Canon 60D built-in 4 different filter effects, namely, black and white particles, soft focus, toy camera effects and miniature landscape. Select the filter effects that we want, you can press the SET button for the corresponding SONY NEX-7 battery effect on the photo set. Here, we take a look at what these filters model has a different effect:

You are not like me to be the Canon 60D shocked filter effects? We operate through a few simple steps can make a simple beautification of the photo. We also found that, through the creative filter treatment, the photos will not overwrite the original file, and the Canon 60D creative post-processing filters can be superimposed effect of the photos.

Although the Canon 60D’s filter effects is great, but the machine only built just four kinds of effects, prolonged use will inevitably feel a little monotonous, for some young people seeking personalized, or a little less. Do not worry, Canon 60D filter effects can also be superimposed. Below this group of pictures is the way we handled this process.

Simply put, the Canon 60D filter effects for the following two advantages: First, when we use the Canon 60D after the built-in filter effects and will not destroy the original image, we just modified the photos “Save As” and not “save”, in this sense is that if we are not satisfied with the photo processing, storage card can be found in the original film, does not make you miss a good photo. The second is easy, when you complete the task the day after the shooting and do not have to wait until the home turn on the computer only after post-processing of photos, we can in the subway or waiting for the bus when the photos to personalize treatment, and very convenient.

Cameras for The Holidays

Each end of the year on a wide variety of holiday Fun to ride, the first Thanksgiving, and then followed by Christmas time, Christmas just past few days to usher in New Year’s New Year’s Day. With the arrival of these festivals, street lighting decoration was also quietly changed, Christmas trees, neon lights are up more gradually, more and more heavy in flavor. For these special holidays, do you like to shot more as memory with SONY NEX-7 battery?

Shooting neon signs and other features is not the same, because only in bright neon lights will be lit at night, so we need to choose is a strong night shooting capabilities of the camera. This camera should meet the following two requirements, first it should have a better sense of ability to control noise high; followed with a relatively large lens aperture as SONY NEX-7 battery. The only way to ensure that we take out at night clean, clear photos.

And today, we will use PowerShot s100w to do this work. As Canon PowerShot s100w coming with a new DIGIC 5 image processors and back-illuminated CMOS sensor, so the aircraft noise in the high sense of control has improved so much; The second is the aircraft reached a maximum aperture of the lens F2.0, large aperture the advantage of in the same light that we can get more into the environment, the amount of light to ensure camera stability when shooting handheld at night. 24mm wide-angle lens is also a major highlight of the aircraft, compared to ordinary 35mm wide-angle camera, 24mm wide-angle lens can not only take a broader perspective but also to obtain security slower shutter speed with Toshiba pa3465u-1brs.

It is worth mentioning that the Canon PowerShot S100V lens wide-angle end to the 24mm, compared to ordinary 35mm lens, 24mm wide-angle screen allows us to accommodate more content into the effect is very shocking. Because the time has come to shoot at night, when shooting hand-held camera in order to ensure the stability, we have the sensitivity set at ISO800 or so. Although the increased sensitivity of the camera, but from a practical point of view the effect of shooting, the Canon PowerShot S100V still be able to ensure good quality. F2.0 large aperture with the machine, completely hand-held shooting night to ensure the stability.

Generally speaking, handheld shooting night in order to ensure the stability, we need to adjust the shutter speed to 1 / 30 seconds, but the Canon PowerShot S100V use this when shooting slow shutter speed to 1/4s or even when they are 0.4s is no problem, thanks to the excellent Canon PowerShot S100V smart iS Optical Image Stabilizer function. It includes a pan, dual IS, IS, including six kinds of powerful anti-shake mode, the camera according to their environment and jitter detection information, etc., automatically select the more appropriate one.

Canon PowerShot S100V high-sensitivity shooting, sample results from the point of view, the performance of the aircraft or whether it is in the details of dark images are very good ability to control noise, and also the stability of hand-held shooting people feel themselves completely a small change in the status of DC-free night. Canon PowerShot S100V and body size is also unique in the advantages, compared to bulky SLR camera, and only palm-sized Canon PowerShot S100V convenience of our portable, very convenient.

When the electronic products becoming more and more portable, do you think it will have some other new types? in the CES 2012 there are some products on shown that they are new type as they can change Lenovo ThinkPad T61p battery the shape.

In successive CES, Samsung’s Dell Vostro 1720 battery booth is often one of the largest in the blue tone of the exhibition hall Samsung launched two new products gorgeous one computer to entice from the exhibitors and reporters. They are part of 7 series and 9 series of two products, targeting high-end, elegant fashion design, configuration in place.

The show, Toshiba unveiled its first desktop integration Latitude D820 battery product. The appearance of the product model for the DX735, is a support TV function, with a multi-touch screen products.

Toshiba DX735 is equipped with one computer Core i5 or i7 processor, 4GB of memory, 1TB hard drive, 23-inch display can be the perfect support for 1080P full HD video playback, running Windows 7 operating system. Onkyo speakers with speakers, built-in DVD drive, HDMI input, USB 3.0 ports, four USB 2.0 ports. In addition, DX735-one computer built-in TV tuner, can be directly used as TV viewing; also equipped with a Bluetooth mouse and keyboard, easy to operate.

Sony unveiled its first in the support of one naked eye 3D desktop. According to reports, the product according to the location of the face, automatically adjusts the naked eye 3D display. Product support 2D and 3D display.

Ultrabook (ultra-extreme version) is a PC products at CES this the most favored form. There are many PC brands show the first time joined the ranks of the Ultrabook, introduce new products. But such products in the exhibition several times before the exposure, makes us feel less surprise, nothing worth mentioning. Although it is still good.

To carry out the first day, and other vendors, the company launched a number of Ultrabook (ultra-extreme version), but a particularly rosy, called YOGA. YOGA 360 ° folding unique hatchback design. If the user wants to close and read on a computer screen, browse the web and audio-visual entertainment, simply fold the screen YOGA establishment type (Stand) or tent.

Lenovo seems to fall in love at the moment of deformation. Released over the same period one desktop products ideacentre A720 also go from a “deformed” line. We first saw the one that can be flat desktop. A720 27-inch touch screen with fingers is simply an oversized tablet. Cool flavor.

If only a Lenovo learned deformation, PC makers were not enough the importance of the traditional PC and innovation. In the Sony booth, we also found a change in the normal laptop. Sony products will be a light (not sure whether Ultrabook) of the shaft part of the forward, effectively reducing the actual area of ​​the notebook. Often a small space on the plane or the use of laptop computers who might fall in love with this design.

Of course, the lack of innovation for some new notebook computers, disappointment are inevitable. We regret to see a few big-name PC makers are still “stuck” to imitate Apple’s design. Even in a PC maker’s launch, Apple copying the style of Keynote. Obviously, this is to belittle self-innovation. Blindly imitate Apple, there would be branded a “cottage” of infamy. Ultimately, only a dead end.

In any case, the traditional PC’s performance at CES, so we are pleased. At least, we have less of this type concerns the fate of the product. Tablet PC is still flying in the era of the traditional PC is still essential production tools. PC makers the importance of these products, so we look forward to. After all, a stylish and practical PC, is with us all-around work-life partner.

How to Choose Digital Camera

Today we will talk about how to choose the consumer-level cameras and not SLR cameras. Although consumer-level digital SLR camera is not professional, but its performance can not be ignored, in order to take full advantage of its strengths, it also requires an understanding of the key performance parameters, such as at the time of purchase are not used by unscrupulous sales you can not read a lot of parameters to fool the camera.

Great friends now go into a misunderstanding, in the purchase of a digital camera, the most concerned about is how many pixels the camera. Indeed, both the consumer digital camera or SLR, camera pixel is a measure of image quality standards, it is easy for consumers to buy digital camera, the focus of consideration. In fact, with digital camera technology, the importance of pixels has slowly subsided with Lenovo ThinkPad T61p battery computer.

Let us first say that it is the imaging principle. Traditional CANON NB-7L battery camera imaging principle is to use film to record images on the photosensitive coating, and digital camera imaging principle is dependent on the photosensitive element CCD camera or CMOS, so that optical signals into electrical signals, and then recorded to the camera’s flash. Number of recorded pixels depends on the camera CCD or CMOS chip number of photosensitive elements, in theory, the more light-sensitive cells, captured images will be clearer. However, due to size limitations of digital cameras, so the relative size of the CCD or CMOS is fixed, so in a limited area on the chip to increase the light-sensitive cells will be too many problems, such as image noise ratio, sensitivity decreased. Therefore, excessive increase in photosensitive element even have the opposite effect.

So when we buy a digital camera, in the end the number of CANON PowerShot-G12 battery pixels in order to achieve our daily shooting requirements? In fact, the size can be judged from the photographs. Here we first explain the next pixel resolution, the image size between the three.

Canon G12 is such a camera, it’s only 10 million pixels, not high the small card, but no one doubts it’s performance, coupled with 5x optical zoom 28mm wide-angle Image Stabilizer lens and a flip LCD display, G12 adequate professional instead.

This refers not display resolution, but the print resolution (dpi), pixels per inch. Generally speaking, digital cameras, taken out of the picture displayed on the computer is 72dpi, although such a resolution on the computer watch is very clear, but if we print it out, they would feel very rough picture. And CCD’s the same principle, when a fixed number of pixels in the higher dimensions, the picture is more clear, so the resolution of photos when printing requirement is 300dpi, which is the human eye can feel the highest resolution, which is that even if the resolution of up to 600dpi, we will not find photos of the fine.

G12 is also equipped with an electronic turntable to achieve SLR camera close to the high maneuverability, and integrated into the electronic level, to confirm the horizontal position when shooting. Canon G12 is not only carrying about 10 million effective pixels for high sensitivity CCD image sensor and DIGIC 4 image processor, noise reduction technology has improved the algorithm so that the image resolution under high-sensitivity shooting further.

HP Folio 13 — Business UltraBook

The term is intended to describe the product Folio design features, and “as thin as paper” is the best description of this Folio 13. But from our experience point of view, relative to the previously listed products,, Folio 13 be UltraBook in the thick of the product. Here, we look at this product in the overall design worthy of our attention on what are the characteristics Dell Latitude e4310 battery?

From the naming of Folio 13, we can already see that this is a 13-inch class product, which is currently UltraBook product “standard size”, but if just from the appearance point of view, it is easy to be fooled that is a 14-inch product, as Folio 13 of the physical border HP Mini 110 Battery is very narrow, narrow border design of this popular design is the popular user mode.

First, Folio 13 gives the first impression is the ProBook 5330m slim version of cap and body parts with a silver brushed metal material to build, grade sense, strong sense of fashion, fine polished panel, showing elegance Business of the calm, the whole machine work is superior. Vertical roof surface polished metal wire drawing process, the center still design “hp” LOGO, metal breath of nature itself.

Secondly, through careful observation, you can still see Acer Aspire 7741 battery Folio 13 ProBook 5330m and of copying the design, crafted in more detail, the body no longer used almost at right angles to the edge of the transition, which also makes the overall look is more rounded, At the same time there is no loss of product and business qualities. Details from the work and the overall design, we can also see the launch of this product when HP is very sincere.

Folio 13 of the display resolution of 1366 × 768 pixels, LED Brightview display as much as possible to minimize power consumption, while the screen display will have a better performance, while color gamut compared with ordinary notebooks and no big difference, but still relatively good color fidelity, clarity is relatively good performance for general business applications, business users, it is enough.

Folio 13 of the interface configuration from the point of view, and did not give up RJ-45 Ethernet port, so the advantage, although it can not make the body more slim, but to provide users with great convenience, do not consider the use of RJ -45 to USB to wired Internet. In addition, Folio 13 in the right side of the fuselage design of an audio jack, a USB 2.0 interface; the fuselage on the left is the design of the power jack, HDMI high-definition interface, a USB 3.0 interface and a card reader.

For UltraBook this slim products, off the roof of the action often than the average notebook on the cost of some effort, therefore, Folio 13 in the top middle of the front-end for the user to set the auxiliary bumps, so users can leave section raised part as the focal point, which is more easily opened cover, reflects the humanization design concept.

Good design, does not mean that the machine can be recognized by the user, want to allow users to completely convinced, must pay more attention to the details of the design.

Heat is the most user attention UltraBook place, because in such a thin body, the thermal efficiency will be affected, but for such products, most of its users use it for business office, and the big game will not run this high-energy applications, so the overall heat dissipation without too much mind, Folio 13 and the bottom of the rear fuselage design of thermal windows, sufficient to ensure the application of this product in the general environment to obtain just the right cooling. While benefiting from the introduction of HP’s own CoolSense technology, but also can make users more freedom to adjust to the heat dissipation.

There are many interesting and major events 2011 in the IT field. let’s make a review of them. Cruiser in December 9, 2011 notice was published, the official cost of 9.7693 million yuan acquisition of a Japanese manufacturer of high-end headphone STAX, expected acquisition will bring advanced electrostatic headphones Cruiser design, production capacity, and promote the to further attack the high-end headphone market as Motorola pmnn4046 battery, Apple MacBook 13-inch A1278 battery and hp pavilion tx2500 adapter.

The acquisition of STAX caused great concern to enthusiasts, movers, chairman Zhang Wendong in the subsequent open letter revealed the brand’s future development plan for the STAX. He said, STAX will operate independently of the way “to continue the operation and is always down.” This includes Meguro Yang made​​, STAX all personnel within the operations team will be perfectly preserved, so STAX will still be 100% of the Japanese R & D, manufacturing, product quality will not change.

Next: Since the total smartphone market share hovered around 2%, and Sony Ericsson co-operation between the decade come to an end earlier this year announced. October 27, Sony Ericsson announced the Sony Ericsson will acquire 50% stake held by Sony Ericsson to complete the transaction Housuo Ni will gain full control of Sony Ericsson. Sony Ericsson Sony subsidiary after becoming integrated into the Internet, consumer electronics platform, the transaction amount up to 10.5 billion euros.

Then: No permanent friends, only permanent interests. This is bolstered by the Wintel alliance relationship is really a great description. As the urgent need to make a counter-attack the mobile space, Microsoft is hoping Windows 8 system to show their power, so impatient to increase support for the ARM architecture.

What’s more: In July, Nortel Canada’s patent battle, has always been considered competitors of Apple, Microsoft actually unite against Google, which only shows that 6000 patent for the future pattern of how important the industry. To lose the war Google has a monopoly of them as malicious conspiracy.

In the August 19 meeting of the third quarter, Hewlett-Packard CEO Apotheker (LeoApotheker) officially announced that it would stop around the WebOS operating system’s hardware, including the TouchPad tablet and WebOS smartphone. At the same time, due to low profits, HP also said to consider the spin-off PC business.But then the company’s inconsistent for the industry to surprise, especially the TouchPad crazy $ 99 after big sale actually received unexpected good results. Resulting in increased supply Hewlett-Packard, the trend is quite back from the dead. The PSG is also head of Bradley singing a different tune, saying the PC business takes a long time to determine ownership, spin-off will be adversely affected.

No matter from which terms, Google on Motorola mobile acquisition of up to 125 billion in 2011 must mention the acquisition of large events. Which involves moving pattern, Android camp development, patent disputes and other sensitive and complex area, so much attention.

February 11, 2011, long-planned alliance Microsoft Windows Phone Nokia officially announced. In the Smart missed this excellent development opportunities in key areas, Nokia has hired to work at Microsoft Stephen Elop as CEO, and along with the “undercover” suspect, Elop to Nokia mobile phone pressure in the future entirely old club over the Windows Phone system.

Storage Media of Digital Cameras

Digital cameras change the image signal into a data file and store on magnetic media or optical recording media device. If the digital camera is the host computer, then the memory card is equivalent to a ThinkPad t43 battery computer hard drive. Storage memory can record image files in addition to accidents, you can also record other types of files, and computer connected via USB, it becomes a removable hard disk. Common NIKON EN-EL12 battery storage media market, the CF card, SD card, SM, Memory Stick, and a small hard drive. Maybe you will see there are many memory card reader in the market, such as 4-in-one memory card reader, all-in-one memory card reader and so on.

CF card:
CF card (Compact Flash) in 1994 first introduced by SanDisk. CF card with PCMCIA-ATA functionality and compatible; CF card weighs only 14g, only a matchbook-sized (43mm x 36m x m3.3mm), is a solid product, that is, work without moving parts. CF card uses flash memory (flash) technology, is a stable storage solution, which does not require the battery to maintain stored data. Of the saved data is, CF card than traditional disk drives security and protection are higher; than conventional disk drives and PC card type Ⅲ 5 to 10 times as high reliability, and power consumption is only CF card for small disk drives 5%. CF card use a voltage between 3.3V to 5V operation (including 3.3V or 5V). These conditions make the most excellent digital camera to select the CF card as its storage medium of choice.

CF card as the worldwide storage industry standards to ensure compatibility of CF products, to ensure backward compatibility with CF card; as more and more widely used CF card, CF card of the company to actively promote the technology, to promote a new generation of body small light weight, low-power launch of advanced mobile devices, thus improving efficiency. CFA headquarters in Canada, Palo Alto, whose members have the free CF card, CF and CF trademarks technical details. CFA members include 3COM, Canon, Kodak, HP, Hitachi, IBM, Panasonic, Motorola NTN7143 battery, NEC, SanDisk, Seiko (Epson), and Socket Communications, more than 120. And one of the major digital camera manufacturers produce R & D has set up a special organization, engaged in the development of CF products.

CF card has the following disadvantages:

1, the capacity is limited. While the capacity increase exponentially, but still keep up with the development of digital camera pixels. The current products have more than 5 megapixels is the minimum specifications of the popular high-end products, while the civilian market has reached the mainstream level 3 megapixels. Ordinary civilian JPEG compression format, the capacity can still be, but the professional level of TIFF (RAW) format, or image data does not fit a few.

2, The size is large. And compared to other types of memory card, CF card size slightly too large, which limits the use of CF card size digital camera, it holds many lessons for most of the popular ultra-thin digital camera gave up the CF card, and switch to a more compact size SD card.

3, Performance limitations: CF card is generally 0-40 degrees C operating temperature. So 0 degrees below the environment, basic digital camera can be turned into a “waste.” Even professional machines are not immune. Although the military capacity of the CF card cold -40 degrees Celsius, but when spread, when the price dropped to the point where ordinary people can afford is still unknown.

Currently the world’s largest capacity CF card type has reached 640M. General common market, is 8MB, 16MB, 32MB, 64MB, 128MB, 256MB and other types (128MB or more of the type Ⅱ).

SM card:

SM (Smart Media) card is a Toshiba released in November 1995, the Flash Memory storage card, Samsung in 1996 to buy the production and sale of licenses, the two companies to become major manufacturers of SM cards. Smart Media to promote the industry standard, in April 1996 established the SSFDC Forum (SSFDC the Solid State Floppy Disk Card, Smart Media, when in fact the beginning is called SSFDC, 1996 年 6 was renamed as Smart Media, and a Toshiba R). SSFDC Forum has over 150 members, also including many large companies such as Sony np-bn1 battery, Sharp, JVC, Philips, NEC, SanDisk and other manufacturers. Smart Media card is a common micro storage card on the market, once the MP3 player is very popular.

SM card size is 37mm × 45mm × 0.76mm (Figure 1), due to the SM card does not have the control circuit, and made ​​of plastic (to be divided into many thin slices), so small SM card is very thin, in 2002, before which is widely used in digital products, such as the old Olympus digital camera and Fuji digital cameras and more use of older SM storage card. However, SM card is integrated in the digital control circuit which products (such as digital cameras), which makes digital cameras compatibility susceptible.

The new digital cameras now have not used in the SM memory card products.

SD card (Secure Digital Memory Card) is a flash memory device based on a new generation of semiconductor memory devices. SD card from Japan Panasonic, Toshiba and SanDisk Corporation in the United States in August 1999 jointly developed. Like a postage stamp size SD memory card, weight only 2 grams, but it has high memory capacity, fast data transfer rates, great flexibility and good mobile security.

SD card in 24mm × 32mm × 2.1mm for SanDisk flash memory card combined with volume control and MLC (Multilevel Cell) technology, and Toshiba (Toshiba) 0.16u and 0.13u NAND technology, through the 9-pin interface and a dedicated interface drive is connected, no additional power supply to maintain its information on the memory. And it is the integration of solid media, without any moving parts, so do not worry about the damage to the mechanical motion.

SD card structure can guarantee the security of digital file transfer, but also very easy to reformat, it has a wide range of applications, music, movies, news and other multimedia files can be conveniently saved to SD card. So many digital cameras have begun to support the SD card.

Many companies have developed a memory card SD card, SD card Panasonic is the leading manufacturer, in 2000, the SD card from 8MB to 64MB capacity has been divided into four different levels to meet the needs of different occasions, the data transfer rate 2MB / s. The end of 2001 single-card capacity has reached 512MB, data transfer rate is also raised to 10MB / s. Panasonic plans to launch in 2003 capacity of 1GB, the data transfer rate of 20MB / s high-performance memory cards, is expected to reach capacity by 2005 4GB. It seems another way of SD card storage media in the digital camera is expected to open in another piece of heaven.

Sony has always been a loner character created memory stick was born. The gum-based storage devices can be used with Sony almost all common audio and video products. Memory Stick (Memory Stick) thin, light, and has a full variety of functions. Its high compatibility and unprecedented “common storage media” (Universal Media) concept for future high-tech personal computers, televisions, telephones, digital cameras, camcorders and portable personal audio-visual equipment to provide a new generation of faster, larger capacity digital information storage, exchange media.

In addition to small form factor, with high stability and copyright protection, and easy to use in a variety of Memory Stick products and other characteristics, Memory Stick Sony’s advantage lies in the extensive use of the technology products, such as DV camcorders, digital cameras, VAIO personal computers, color printers, Walkman, IC recorders, LCD TV, the PC card adapter, 3.5-inch floppy disk converters, export converters in parallel and USB reader memory Stick and other line of accessories enables easy integration with PC and Mac connection.

Memory Stick launch, Samsung, Aiwa, Sanyo, Casio, Fujitsu, Olympus, Sharp, and a series of companies have expressed support for this format. Sony’s consumer electronics industry is also being sought and the IT industry on the Memory Stick format recognition. Sony will put more in the future on behalf of Memory Stick products introduced to the latest developments in the domestic market.

One disadvantage of Memory Stick can only be used in Sony digital cameras, and second, the capacity is still not big enough.

Battery Types

Today we will talk about the battery types of camera batteries. Digital cameras need batteries to maintain normal operation. Under normal circumstances, a digital camera can work with dry batteries, alkaline manganese batteries, nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries and lithium batteries as its power source. At first let’s see some batteries such as: Lithium-ion ThinkPad T43 battery, Sony Np-bn1 battery, Ni-MH Motorola NTN7143 battery Canada and so on. Before you buy a camera do you mind if the camera work with which type of batteries?

Ni-MH battery
This battery is an early alternative to nickel-cadmium batteries, nickel-cadmium batteries as opposed to, nickel metal hydride batteries with more compelling advantages such as Motorola hnn9008a battery canada. It greatly reduces the presence of nickel-cadmium batteries in “memory effect”, which makes nickel-metal hydride battery is more convenient, longer cycle life (up to 1000). In addition, Ni-MH battery also has a high capacity, depth of discharge, resistance to overcharge and over discharge, charging time is short and obvious advantages. The most important thing is to use nickel-metal hydride battery is no longer toxic heavy metals as a material, can eliminate the pollution of the environment. Meanwhile, the electrical characteristics of areas with similar nickel-cadmium batteries, in practical applications can replace nickel-cadmium battery for any camera without the need for transformation.

Of course, the nickel-metal hydride battery is not perfect, it also has some disadvantages. Its relatively poor high temperature characteristics, temperatures above 45 degrees Celsius and 0 degrees Celsius environment of low temperature, nickel-metal hydride battery will not work, or simply can not start the camera; In addition, the battery self-discharge rate is relatively high, and stored for some time will find it significantly reduced power; there is a nickel-metal hydride batteries, there are also slight memory effect.

Alkaline manganese batteries
This battery is very easy to buy in the market to get the 5 batteries, and they do not go through special materials and technological innovation, the cameras use this type of batteries, which mostly are the low-end digital camera products. Because a wide range of marketing, so users do not need to worry about the price of the battery, but also because of technical general, the power supply and endurance far more than inferior to other types of batteries. Sometimes, these batteries can not offer enough power to start the digital camera, and even do bad affect to digital cameras.

Lithium Battery
Lithium-ion battery price is relatively high, but it has a light weight, large capacity, energy density advantages, compared with the nickel-hydrogen batteries, lithium-ion battery more lightweight, and has higher energy than 60%. Because of this, lithium-ion battery production and sales are gradually than nickel-metal hydride batteries, a digital camera is now one of the main use of the battery. In addition, lithium-ion battery is almost no “memory effect” and does not contain toxic substances, etc. are also important reasons for its wide range of applications.

Lithium-ion batteries and lithium battery technology, health, performance is better than just slightly higher price, but also use more attention, complex, particularly lithium-ion battery charger must be “special”, it can not charge the battery with other compatible. Alkaline-manganese batteries, although the price is low, consumers can afford, but its short life, long-term use for the average consumer is difficult to bear the costs. In contrast, nickel-cadmium batteries, nickel hydrogen battery technology is more mature in the manufacturing, prices are more reasonable battery.

If you are using does not match nor do not pay attention to save the battery, the battery will take a few photos in when you do not run out. The following ways to save NIKON EN-EL12 battery consumption:

  • first, to avoid unnecessary use of the zoom operation;
  • second, to avoid the frequent use of flash, the flash is a big power, we try to avoid using;
  • Third, adjust better to use the viewfinder when the picture composition device, instead of LCD. Because most digital cameras are due to open the LCD viewfinder and consume more power, turn it off can increase two to three times the battery standby time;
  • fourth, minimize the use of multi-shot. Mostly, digital camera’s continuous shooting function use the built-in cache to temporarily store digital photos. If you frequently use the cache, then the power required is very large.
  • Therefore, reducing the use of video shooting and video recording function will help to save power greatly.
