Comments: Comments Off

Few years had past, and this was a long term wait. Nikon was finally officially released on February 7, 2012 its D800 and D800E a new full frame camera. Largest characteristics of both cameras is pixel from the D700 12,000,001 jumped before reaching as much as 36 million. Although prior to the adoption of the official sample, we have taken on Nikon D800 has a general understanding of the performance, but the machine in high noise control continues to know enough of NIKON EN-EL19 battery.

Recently, some friends found the Nikon D800 threaded test sample as NIKON Coolpix S630 charger from France the photographer’s personal website to speed of , here we take a look at this new “pixel King” by the camera’s performance in controlling noise levels will have on how to charge NIKON COOLPIX S550 battery.

Difference between Nikon D800 and D800E

Before you begin, I need to briefly explain the difference between Nikon D800, Nikon D800E. These two cameras on both the appearance and the parameters are the same, only Nikon D800E of low-pass filter with special “train”, in theory, has a higher resolution. Effect of the low-pass filter is mainly reduce moiré when the shooting occurred, but also makes the picture is missing part of the details, reduce sharpness.

The shooting with a total of three different scenes, the author would intercept most representative part of the screen respectively in order to facilitate comparison. Red circle in the figure below is intercepted by the author of the site.

Official data is nominal, standard sensitivity range from ISO100 to ISO6400 Nikon D800, lowest scalable down to ISO50, the highest scales up to ISO25600. For fun, here we are going to take a look at the real shot performance of the machine under the speed at all levels.

First of all, we take a look at the first shooting scene, from the perspective of overall on the lighting effects for your pictures, when shooting objects around the ambient light should also be adequate so that ambient light is the most common and most photographers most commonly found.

Ambient light is weak, so the Nikon D800 on the purity of the screen than on a scene somewhat less, to a small amount of noise in ISO800 picture, along with the enhancement of sensitivity to ISO25600, the screen appearsa slight color cast.

All the people who read the Nikon D800 Sample all agree that the Nikon D800 is worthy of the “Year of the Dragon artifact of years. Compared to its predecessor, Nikon D700, Nikon D800 in the pixels of a three-fold increase still continues the high sense of quality of the D700. 36 million effective pixels also allows photographers in the latter has a more relaxed space for cropping. ZOL digital imaging division will later give us some more Nikon D800 comprehensive evaluation and trial reports, as in 2012 the highest attention SLR products, we will certainly be the highest gesture of treatment of this product, all please look forward to!

So many people asking them not from their pictures from a digital camera to your computer. For all of these types of problems, I suggest you can use a card reader with SONY NP-FP50 battery camera, easy to move your pictures. And in this way, you can also extend the life of your Sony Np-bn1 battery camera card slot.

Some digital cameras, with a small hard disk memory, which means you can save up a few photos, there is no SD card in your camera. However, if you have a card into the camera, you may not be able to find your camera, camera pictures on hard drive memory, so you need to connect the camera to the computer and move the pictures from the camera to the PC.

And some of my friends worried about another issue: their batteries of cameras, it died in a matter of minutes.

I think this is their digital camera batteries, nickel-metal hydride? You can try to use Kodak camera battery lithium-ion battery, and see if there is any help? The problem is that on some of the common Canon camera model, because the voltage of NiMH batteries camera is better than lithium-ion, judge of the camera in real time low battery level low.

Some people asked that their Sony Cyber shot Sony NP-BN1 charger digital camera, when it is displayed on the screen, he tries to exchange it as a system error message. And he got a SD HC16GB memory card, the camera. And noted his memory card the camera is full of such problems before they occur. But he thought it was, in reality this is not the case. And his camera, with another card.

In my opinion, he has found your camera manual to see, if the camera can support 16GB memory card. Not all cameras can use a large-capacity memory card, because there are a limited number of may in the camera manual written.

However, this does not seem to work. When everything fails reading instruction. However, from the manual, says “memory card 32GB has confirmed that properly functioning of any other suggestions, please use the camera. He said he also took some video problems before they occur.

Because he had taken some of the movie before the problem occurred before the card can be used. This means that the card is suitable for your camera. He can read the card and card reader on a computer to see your card details. If it is really not. Formatting the card he, you can solve this problem, has moved his useful files to your computer. You can format your card in your PC supplely.

Do You Know the Useful Of ISO of a Camera?

Comments: Comments Off

My sony cyber-shot T99 with NP-BN1 has been used for longer than a year and in these days I found that, the picture quality are so lower than before, and I remember that. The first few times we travelling with my T99 with Sony NP-BN1 battery and the size of the pictures are over 4M, but now, the size of the pictures are less than 1M.

At first I haven’t notice this problem, and then I found that. Only one day, the picture are so many impurities of granular. And I know this maybe caused by my wrong setting of the Sony cyber-shot T99 battery camera. Then I thought up that, in these days, the camera is always on the status of high ISO.

So let’s see the useful of the ISO:
First, the meaning of high ISO is high sensitivity. Camera iso we often have the words in the parameter list of some digital cameras. The product ISO sensitivity ranges from 100 to 6400, this is what does that mean?Most digital camera’s ISO range is from 100 or 400, the sensitivity of this applies to most outdoor shots, so this should also be the default sensitivity settings of your camera.
What are the conditions to the use of high light-sensitive?, Camera iso, the Canon pairs DIGIC4 processor
Sensitivity value per doubling, doubling means that the sensor light sensitive. For example: the ISO from 100 to 200, a shutter speed can be improved. Most digital camera sensitivity can reach 32, and some digital SLR cameras can reach 12,800 or even higher. But note that the different types of products of different brands under the same ISO sensitivity, the final picture quality is not the same as Acer Aspire 7741 battery, this is the charm of photography.
Under what circumstances the use of high photosensitive
The little book cited several higher sensitivity to complete the shooting scene. Of course, not exclude the deliberate use of the low ISO to get the special effects.
Handheld shooting
Handheld shooting, in order to ensure that camera shake does not affect the sharpness of the picture, the reciprocal of the shutter speed in the normal circumstances should be greater than the focal length. For example, assume you are using a 50mm fixed focus head, the safety of handheld shooting shutter speed faster than 1/50 seconds, this will ensure that the impact of camera shake on the picture minimum. Therefore, in order to ensure that the shutter speed, you can increase the ISO.
Moving objects
The reason is probably the same, shooting moving objects and handheld shooting are need a higher shutter speed, so raising the ISO.
Need flash
When you use the flash when shooting the main farther away from the flash, the flash output power is limited, then increase the ISO is the only option.
Summary: manually set the ISO, the time came to see several students alone was the security held (Photos? Ka Ying micro camera driver is one of the basic essentials SLR camera, in a word is to ensure a certain aperture, shutter, try to use the lowest ISO to get good image quality.

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

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.

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.

Comments: Comments Off

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.

Comments: Comments Off

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.

Comments: Comments Off

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?

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.

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.
