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.

Did You Note Camera’s Shutter Speed?

Comments: Comments Off

When you choose a Sony NP-FT1 battery camera before buying it, what will you mind? The pixel, CCD size, flash, lens, the appearance or the screen? But do you have ever note the shutter speed of a Sony NP-FT1 camera?

Digital camera shutter shutter speed is an important study parameters, the various types of digital camera’s shutter speed is completely different, so use a type of Nikon En-el3e battery digital camera to shoot the scene, we must first understand the shutter speed, because press the shutter when the shutter is only considered a start-up time, Nikon En-el3e shutter release and time to master in order to capture the vivid picture.

Usually most common digital camera shutter at 1 / 1000 seconds, basically to meet the majority of everyday shooting. Shutter not only depends on the “fast” depends on “slow” is the shutter delay, such as some digital cameras with up to 16 seconds shutter, but enough shooting night, but also increase the shutter is too long digital photos of the “noise “is the photo will appear mixed stripes. In addition, the mainstream of the digital camera in addition to automatic shooting modes, but also must have aperture priority mode, shutter priority mode.

Aperture priority mode is determined by the aperture size of the user, then the camera and exposure settings according to ambient light, etc. to calculate the amount of light to enter, according to this model more suitable for stationary objects. The shutter priority mode, that is, the shutter speed determined by the user, and then calculated according to the environment of digital cameras suitable aperture size. Therefore, the shutter priority mode is more suitable for shooting moving objects, in particular digital camera is very sensitive to shock, during exposure to even slightly move the camera will produce a blurred picture, long focal length in the practical situation is more obvious. In the purchase of a digital camera, you’d better buy the model with these types of models to ensure the capture effect.

The common B SLR camera shutter function, although you can be free to decide the length of exposure time, higher flexibility in shooting, but now most consumer digital cameras also can not support, such as providing up to 2 seconds, 8 seconds, 16 seconds, etc. the default value for a slower speed.

What are CCD?

Comments: Comments Off

When we are talking about the size of CCD in fact we mean the size of the light-sensitive device, which includes CCD and CMOS. Photosensitive device size, CCD / CMOS area is larger, can capture more photons and the better photographic performance, lower signal to noise ratio. CCD / CMOS are used in digital camera as imaging sensor parts, the optical equivalent of the traditional camera film. Need a iPad 2 bluetooth keyboard case for your iPad 2 as a Christmas gifts, or a APPLE Powerbook g4 battery?

The surface of the CCD light-sensitive components is able to storage electric charge, and it arranged in a matrix manner. When the surface feel the light, the charge will be reflected in the components, all of the CCD light-sensitive components on the signals generated and make up a complete picture with this Sony NP-FD1.

You will find there are three layers of the CCD if it be decomposed. And the first layer is the “micro lenses”, the second layer is the “color separation filter”, the third layer “light-sensitive layer.”

Micro-lens
We know that the key to a digital camera imaging is in its photosensitive layer. In order to extend the CCD light rate, we must extend the light area of a single pixel. However, the image quality will be down easily by improving lighting rates. This layer of “micro lens” is equivalent to the photosensitive layer by adding a pair of glasses. Therefore, because the sensor is no longer sensitive area of open area and decided, instead of by the micro-lens surface area to decide.

Dichroic filter
The second layer of the CCD is the “color separation filter”, there are two separation methods, one RGB color separation method, the other is the complementary color CMYK color separation method Both methods have their advantages and disadvantages. First, let’s look at the concept of two kinds of separation method, RGB is RGB color separation method, almost all human beings can identify the color of glasses, are available through the red, green, and blue to form, three letters, respectively, while RGB is Red, Green, and Blue, which shows RGB color separation method is through these three channels of color adjustment is made. Besides CMYK, which is made with four-channel color, they are green (C), magenta (M), yellow (Y), black (K). In the printing industry, CMYK is more applicable, but less than its adjusted out of the RGB multi-color.

Primary-color CCD image quality advantage of sharp, true color, but the disadvantage is the noise problem. Therefore, we can note, the general color CCD digital camera, the ISO sensitivity probably does not exceed 400. In contrast, a more complementary color CCD color filter Y yellow, in color to distinguish the more carefully, but at the expense of some image resolution, and in the ISO value, the complementary color CCD can tolerate a higher sensitivity, which generally can be set at more than 800.
Photosensitive layer

CCD of the third layer is the “sensitive film,” This layer is mainly responsible for the light through the color filter layer into electrical signals and transmitted to the image signal processing chip, the image restore.

Traditional camera film size 35mm, 35mm for the diagonal length, 35mm film of the photosensitive area of 36 x 24mm. Conversion to digital cameras, close to the diagonal length of about 35mm of, CCD / CMOS size larger. SLR digital cameras, many have close to 35mm of CCD / CMOS size, such as Nikon D100, its CCD / CMOS size area is 23.7 x 15.6, compared to consumer digital camera to be much larger, and the Canon EOS-1Ds CMOS size is 36 x 24mm, 35mm reach the area, so imaging is relatively good.

Now the consumer digital camera market, there are 2 / 3 inch, 1/1.8 inch 1/2.7 inch 1/3.2 inch four. CCD / CMOS size larger photosensitive area is larger, the better imaging. 1/1.8 inch 3-megapixel camera effect is usually better than 1/2.7 inch 4.0 megapixel camera (which the light-sensitive area of only 55% of the former). The same size CCD / CMOS Pixels increase of course is a good thing, but this can lead to a single pixel of light-sensitive area of narrow, there may be underexposed. However, if the increase in CCD / CMOS pixel at the same time want to maintain the existing image quality, it must maintain at least a single pixel in the area do not reduce the increase on the basis of CCD / CMOS total area. Currently larger CCD / CMOS processing more difficult, the cost is very high. Therefore, CCD / CMOS digital camera a larger size, the price is higher. Photosensitive device the size of the digital camera directly affects the volume weight. Thin, lightweight digital camera is generally CCD / CMOS size is also small, and the more professional digital camera, CCD / CMOS size is also greater.

Now you should know that, when you judge if a camera is better than another, you should not just judge it by the pixel.

To Know More about Your Camera – Effective Pixels

Comments: Comments Off

At first I will show you a example: The effective pixels of Sony T99C is 14.1 million, and the effective pixels of Nikon P7000 is 10.1 million, which is batter, can we compare them just by this value? Need a Nikon P7000 battery? or a Sony NP-BN1 battery?

From today, I’ll write some post about the basic knowledge about cameras, as help the common users learn more about cameras such as, the knowledge about CCD, Continuous Shooting, Battery Type, Memory Media, Effective Pixels, Shutter Speed, Stabilization Performance and so on. And today, this post is about the Effective Pixels.

I think we will be familiar with that, when we saw the camera adds, or when we step into the camera store, we will see or hear that, XXX camera is with Effective Pixels. of XXX, with XX times zoom and so on. Though the Effective Pixels can’t really reflect the camera’s performance, but of course it’s an important index.

Effective pixels is different from the largest pixel, the effective pixels means the real pixel value in photographic imaging. And the value of maximum pixel is the true pixel of the light-sensitive device (such as CCD), the data usually contains a non-imaging part of the light-sensitive device, and the value of effective pixel is converted under magnification zoom lens.

Digital images are normally stored in pixels as a unit, where each pixel is the smallest digital picture units. The higher pixel, the larger of the size of the picture will be. To increase a picture size, if not more light into the light-sensitive device, the only way is to increase the size of pixels, so that may affect the intensity and clarity of the image sharp. Therefore, in the case of the same pixel area, a digital camera to get the most out of the image pixels is the effective pixels.

Users to buy digital cameras, they usually see the businesses advertised “maximum pixels of XXX” and “effective pixels of XXX”, and then the user should choose? When choosing a digital camera, digital camera should focus on the effective pixels to see how much the value of effective pixels Image quality is the key to the decision.

But only pixels can’t show which camera is batter, and the other important index is the size of the light-sensitive device. And we will talk about it in the next post.

Continue with the Recommended of Entry SLR Cameras, and you can choose these batteries too, such as HP Probook 4330s battery, HP elitebook 6930p battery , and IBM thinkpad t500 battery.

Nikon D5100

Nikon D5100 with 16.2 million pixel DX format CMOS image sensor and can shoot full HD 1080P video images, 3-inch 920,000 pixel flip-out LCD screen, so shooting more convenient. 4 / second continuous shooting capability is also an entry-level SLR in the mainstream.

D5100 DX-format CMOS 1620 used-megapixel image sensor and EXPEED 2 image processor, and more high-end configuration the same as the D7000 can capture high-resolution photos, perfect performance of the image colors. Camera to improve performance, support for the standard sensitivity ISO 100-6400, the maximum may be increased to Hi 2 (equivalent to ISO 25600), even in low light situations, such as at night or indoors, can capture fast-moving the subject, showing wonderful the effect.

D5100 camera with 3-inch, approximately 921,000-dot high-resolution multi-angle flip display. In addition, the display range of reproducible colors is equivalent to the sRGB color gamut. Multi-angle display can be turned to the side of the 0 ~ 180 °, is turned on, can be rotated clockwise to a maximum of 90 °, the maximum counter-clockwise 180 °. D5100 digital camera with video function, can record full HD video (1920 × 1080p, 30p), shooting video when using contrast-detect AF to automatically focus.

Nikon D5100 SLR camera performance with the mainstream configuration of 16.2 million pixels, 11-point AF system, 1080P high-definition video, 3-inch flip LCD screen, and the EXPEED 2 image processor, are so D5100 can provide convincing performance and quality performance. The HDR mode functions and add special effects, but also to D5100 users can easily shooting great photos. Currently the price getting lower and lower, like this friend of SLR can be shot.

Canon 600D, CANON EOS 600D Battery Grip

Canon entry-level DSLR 600D, with 18 million pixel imaging capability, and use DIGIC4 processor the image, with 1080P full HD video capture capability. Whether effective pixels, processors, LCD screens, or other additional features, Canon 600D is King of the current entry worthy performance in the field.

EOS 600D, with 18 million effective pixels CMOS image sensors, and can achieve high performance DIGIC 4 image processing digital image processor, Canon EOS 600D space flight for the first time in scene analysis systems, more efficient automatic shooting modes on the basis of “intelligent auto”.

600D not only inherited the EOS 550D characteristics of light, also used on the EOS 60D, by the rotating LCD monitor. At the same time, a built-in Flash with wireless Flash capability, wireless control external flash. These are high performance provides support 600D grow.

Canon entry-level DSLR 600D, performance configuration absolute toughness even approaching their mid range model 60D. Falling prices, price/performance gradually improved. Using a rotating screen, “intelligent auto” and creative filter mode, then let the camera easier to use and more play-ability.

These entry-level SLRs are 18-55mm F3.5-5.6 specifications of the machine is equipped with anti-shake lenses, although work on optical quality and are among the lower-end products. But for the average user demand, has been fully met. These five single lens reflex cameras, set high pixels screen (high quality), HD video, and other functions all in one, even lots of things have been rival mid-range DSLRs. All prices of less than $ 5,000, then let them have a high level of value for money. Last hope that through our introduction can help consumers buy DSLR.

Reviews Of Canon S100V

Fist let’s have a look of the appearance of this Canon S100V. This key interfaces part of this Canon S110V, if one word to sum up that is not more complicated, in my opinion a professional DC this design is still very correct. And the CANON NB-5L battery and the memory card which you can read by a SD card reader are still in the same box.

canon s100v

We can see the camera’s buttons much, so good control is how to achieve it, naturally, is the S series special control loop, the control loop on the back I will conduct a detailed analysis. Interface part is the same with this level of product, using the USB / video composite interface and mini HDMI interface in the form of combination HP Mini 110 battery.

At the same time, this new combination of CMOS devices also inherited the excellent “control noise genes.” Within the ISO 1600, ISO caused by the increased attenuation of quality are maintained at a relatively linear levels until the ISO3200 quality was noticeable reduced.

Canon S100V with a new CMOS sensor and new DIGIC 5 image processors, because these two core components are the first time in DC in the first time such high-end, so for their performance, the author gives a very big concern. First, the CMOS sensor is not good at low ISO picture quality, S100V basic guarantee for the relatively delicate, after all, 1/1.7 inch sensor size as the support, or can clearly feel than before 1/2.33 inch back-illuminated CMOS income was more delicate camera sensors, level.

Many of my friends say S100V may seem compared to the previous generation of product it is very small progress, but if you look to change many of its inherent nature to understand. If a camera is obviously not just mean a change of shell, only for the internal and external changes do not do too much more can be said to be a good upgrade.

Canon S series is one of the characteristics of pre-control loop, the loop can be selected according to the needs of users they need to change the parameters only need to rely on the back and front of the Ring key ring can be achieved almost all of the function。

Overall, Canon’s high ISO performance, or S100V progress is obvious, and even a few years ago the SLR to spell it, although the inevitable loss of detail, but the number of colored noise is very rare, this is very commendable. At low ISO, the true S100V did not appear grainy small size CMOS, can be too reactive. But if you are a downright “scenery control”, then the G12 photos with the soft and solid “CCD taste” seems to be more suitable!

Arguably, this design does not increase too much in the case of keys and the click wheel to achieve a really good sense of control, of course, you want to do high-speed operation also takes time to adapt, which is the need to have a Hp Pavilion dv9000 battery professional quality DC is good or bad on their own ask you to judge.

Accessories is a measure of a camera is a good professional standards, the official Canon specially prepared for the S100V 2 parts, a for the external flash. As S100V has its own wide-angle 24mm, so the flash range also needs to take into account the relative.

Then we take a look at Canon S100V high sense of performance, because switching to a new high speed CMOS and Digic5 processor, so the S100V S95 bound to the high sense of performance have improved significantly.

What’s RAW Format

by Dou

Comments: Comments Off

These days a friend of mine recently bought a SLR camera took to find me complain, saying that his newly purchased camera had a problem, obviously inserted into a can hold 800 photos 8G card and NIKON EN-EL12 battery, only to shoot more than 160 photos, tips on storage space is full! And viewed on a computer memory card also found that a lot of memory cards which appear useless “junk files.” Camera can also produce garbage files? This statement is the first HP Mini 110 battery time I heard. I was helping my friend set up a detailed inspection of the camera and found that he had inadvertently opened a RAW + JEPG the recording, no wonder the card will be a lot of open files. Given a lot of novice players RAW format files are not familiar with, I take this opportunity to explain in detail to you under the RAW format to use.
What is RAW format in the end?
In the current SLR cameras of all formats are selected photos so an option to buy a lot of novice players after the camera will set its annual JEPG option on Lenovo IdeaPad Y450 battery laptop, for the RAW format, many users are not very understanding. RAW Single literally interpreted as “raw”, we can be understood as a digital camera without any treatment within the image data, which reflects the image sensor is obtained from the most primitive information, can be said true sense of the digital negatives.
RAW and JEPG where the gap?
① different file sizes
Image files are the same, RAW and JEPG between Dell Latitude D620 batteries what are different? First, the file size from the size of our point of view, RAW format files significantly larger than the JEPG format much difference between the two is almost four times the volume NIKON EN-EL12.
The reason why the file size will be such a big difference, because the RAW format records the raw sensor information, without losing any information; and JEPG format is the compressed image file, it has a large proportion of the image file compression. Although JEPG visual loss is almost imperceptible, but the greater the compression ratio, the higher the degree of consolidation, the more color loss, so JPEG compression is “loss” compression.
This is why we use the camera shooting RAW + JEPG format, you can take a picture of dramatically smaller number of sheets of reasons. Therefore, I suggest, if you do not have large-capacity memory card, and want to take more photos or choose JEPG format shooting better.
② different quality
Since the RAW file size much larger than JEPE format, then when we sacrificed the same capacity memory card will be what good is it? The answer is – quality improvement. Here we compare the two groups to see them through the quality difference.
Than the figure we can clearly see, RAW image format, image format than JEPG more solid imaging some of its clarity and detail in the picture have increased in extent, and the details of expression in the picture is much richer some. Because RAW format records the image sensor receives all the information, so compared to after the “lossy compression” JEPG format, it will be better on the photo quality. Does not want to spend a penny to enhance the quality it? RAW with it!

Does not want to spend a penny to enhance the quality it? RAW with it!
③ open in different ways
For most people, when in the open JEPG format images has never been considered the question open way, you can directly double click the file to open, if you are a post-up man, you can also use a variety of imaging software to open JEPG file, but the RAW format files can not directly use the conventional image viewer software open.
Generally speaking, we can use to buy the camera comes with the official CD-ROM software to open and export the RAW format, which is a better choice. Of course, if you have more than one brand of camera, you can also choose to use third-party application software to open the RAW file, where I recommend using Adobe’s Lightroom software development.
The new Adobe Photoshop Lightroom software is the professional photographer’s essential toolbox, it provides a management restructuring and showcase large volumes of digital photographs of a simple application that allows you to spend less time before the computer, and will be more time for the shooting. Here I will explain to you under a simple software how to use Lightroom.
When we click the “Import Photos” option, we need to interface to the left of the “source” in the address to find the pictures, and then check the photo you want to import, and finally the bottom right-click interface to import photos button.
Then we can Lightroom software to view the photographs, but if every time we want to see photos of the import steps to go through this, then obviously it is very troublesome, so we need to photograph the “Export”, into ordinary JEPG format. This is not only retains the high quality RAW, but also make the files in a variety of plug-compatible software.
Finally, click the Export button, we can get the same quality of a JEPG and RAW image files, not only its file size is significantly reduced, but also help us to use almost all of the plug-in software to view the pictures.

Of course, if we use a lot of storage space in return is only limited to quality improvement, that’s too overkill, RAW format photos can be another major feature of destructive changes.

Do You Need a DSLR Camera

Comments: Comments Off

Yes, we always saw many cool DSLR cameras and many people can’t help to buy one. But do you think about if you real need a DSLR camera? If you are a related industries person HP Compaq 6515b battery, of course you need one, if you are a amateur you also can buy one, else, DSLR camera is not a good choice. Let’s see why.

SLR is a structure that does not mean that the professional CANON EOS 5D Mark II battery grip, as we can not say more professional motorcycle than a bicycle, using SLR camera also does not necessarily lead to better photos. As a tool, SLR, rangefinder or small DC and there is no more professional than anyone else’s problem.

Canon 5D Mark II Battery Grip

Do not buy the camera you need HP Compaq 6715b battery, if you lack this concept, there is a very simple test: If you do not want to buy a complete read the manual digital SLR, and understand more than half, do not buy.

For professional camera work is reflected in the indicators and on. Professional cameras are often used to meet the professional needs, if your demand is 1, then you do not need a capacity of 3 of the camera, because in order for it to meet your needs, you must pay the price of 3 and 2 to learn the knowledge, which is obviously is a waste. Spend the price of learning a knowledge, can also meet your needs. In addition to meeting the former self-torment you desire to show off, or outside, it is not a good choice. Cameras such as Sony A33 will be a better choice if the price will be lower.

Even if you are rich or want to have a high-end camera, then with the deepening of market segmentation, high-end DC market is forming, and soon the price is lower than the high-end low-end SLR will be a common phenomenon in DC , those delicate, slender white elephant products may be far more suitable for your.
For the professional photographer is reflected in the photo, the photo water standards reflected in the ideological content and focus, exposure and other technical indicators. Technical indicators for the service of ideology, they affect the expression of ideas, but do not allow ideology to shut up, loss of thinking technical indicators, it can only be a bunch of beautiful garbage.

Has by no means buy a digital SLR kit on the end, if you are satisfied with the kit lens, then the anti-pay is a mistake. Entry-level SLR kit lens quality is often poor, with its picture quality even better than the DC, of course, you will soon discover this, but it’s another cheap shot you can sell unwanted. Such as selling online often see four or five hundred of the new Canon 400D kit lens, is always popular.
Systems as a shot, what a memory card, spare battery, tripod, camera bag, etc. Which will lead also indispensable, must buy. And if the first purchase was inappropriate, and even repeated again need to invest money, time, you will find yourself actually can not afford a set of SLR system. As the saying goes, easier on the pirate ship, pirate ship under difficult, some indifferent, some people may have painful death.

As we said in the beginning of this article, you will want to understand all aspects of SLR cameras, this purchase will be targeted to meet your needs, based on not wasting money. In subsequent use, you also need the basic knowledge to guide the use of SLR in order to play all the energy, not just a waste of money.
First, we wish to purchase models must read the instructions, of course, to compare and select, you can have a choice of several models or brands to look at the manual.
