The whole computer in the most common and most are easy to overlook components is afraid is the mouse. The mouse because often use and become extremely easy damaged parts, so the mouse should how to maintain? A mouse in the use process are the note skill? Or look at the author below to bring dell inspiron 9300 series laptop fan you introduce it, maybe after some adjustment after you will find it moves up more smooth, the input of the reaction to your instructions more sensitive, more in line with your individual needs.

The use of the computer mouse maintenance tips: always clean up

Due to internal optical mouse have simple structure characteristics, especially for ordinary users is concerned, it dispense with traditional mechanical rat difficult to clean up for the biggest, so in a short time he has gained popularity. Although say optical mouse basic to eliminate the dust into the internal structure has caused problem, but in fact some of the design and production of the low price inferior rigorous enough optical mouse inside will still get the dirt, this will seriously affect laser reflection strength, even lead to laser locating the exact situation.

In fact as long as pay more attention to the maintenance of the optical mouse at ordinary dell inspiron 9400 series laptop fan times and use details, a lot of problems can be solved. For example in the use of optical mouse, don't let the strong sunshine on the mouse board, otherwise it will cause the sun to the mouse "light in the" interference, make the mouse failure. In addition, we don't think that the photoelectric mouse will not have to use the mouse pad, you try to use suitable for optical mouse with mouse pad (the same color as far as possible), and regular cleaning, can ensure that your photoelectric mouse longer service life.

A computer mouse maintenance skills

Wireless mouse maintenance:

1. When not in use at ordinary times, can take it out, pay attention to the battery has no electricity.

2. Electronic circuit to damp mildewy, or key failure, this is the common fault of the wireless mouse, a single component circuit board had little problem, see you luck, but also not be able to fix. Open from the dust, use alcohol wipe mildew fungi.

3. If you find the mouse can't move, the mouse receiver away from metal surface, receivers, and on the mouse generally with a key communication, try and at the same time in few respectively, and then see the effect, the mouse and the receiver had better not stopped.

The use of the computer mouse maintenance tips: software maintenance

The mouse driver has certain dell inspiron b120 series laptop fan compatibility, can be interchanged general. To give full play to the driver flexibility, should try to use the original mouse driver. In the use of certain application, application bring the mouse driver, these while your application is running to be automatic loading the mouse driver, so may with the mouse to own driver conflict. The most common is the video card and driver of the conflict between the mouse. This conflict on the surface not easily by notice, but in the use of video card with practical tools to change your screen resolution, Windows will produce a GP (general protective errors).

"Under the tree falls, shredded pork, soup YingHuaBan." Japan Pai holy basho extolled the cherry blossoms, "in order to most life breath way to the reader is a picture of the ambience hanami spring breeze breeze picture-fell sakura profusion, people holding hands in tree delicacies happiness and laughter. So how can the beauty of the longing that no one? Believe that you and I will take the shutter a hot impulse.panasonic cgr-d14 battery But in the beautiful scenery of the record, you know what needs to know about shooting cherry blossom? In this warbler fly YanYu, spend jin YangYan of season is coming before, we summarized the sole filming for you cannot not know of the five elements blossoms.

Prior to the levites for the good

Although small make up is never a photographic equipment fancier, but can also be very responsibly tell everybody, for a particular subject ready to shoot good equipment is half of success. For selecting the shooting the blossoms equipment, can be summed up in three key words: "large aperture", "long", "macro". The Japanese have a minyan said: "cherry blossoms 7", is a cherry blossom from the open to fade about for 7 days. It is for flowering short, so in the cherry blossoms, visitors will stick to enjoy flower, and thus inevitably will appear very noisy scenes. If you don't want to spend more than taken from the "grand occasion" must think about how to streamline background. Large aperture can achieve a very good background throw the effect, this does not have taken Oriental cherry mixed and disorderly background take eyeball.

Use telephoto lenses can not only realize the background falsified, still can form of background effectively cutting, will be unnecessary mixed and disorderly background in QuJingKuang away. And the macro lens is for the film features and raw, not only can maximize the avoid environment of the main body of the shooting to influence, but also to a handful of cherry blossoms's beauty and the interpretation of incisively and vividly. For the realization of the three key words, each of the 70-200 F2. 8, 100 mm macro lens, 1:1 around the telephoto fixed-focus camera, it is right choice. If I could use 200 F2. 0 this artifact is more to force.

In addition, most enjoy flower visitors with a companion line, bound to a group photo with cherry blossom for memory, so we choose to some kind of lens upper wide Angle. 24 mm, 35 mm and 50 mm focal length lens is so taken very group photo. Because of this kind of filming "going on it as" don't need background throw the effect, so aperture size and don't have a lot of influence. If there are 24-70 F2. 8 such high quality zoom lens must be better, but even if not, general camera set of head is completely can be competent.

Do not change to the use of digital camera lens person, choose equipment and easy. General small camera functions are very good macro, big zoom than camera is also very popular, basically can cope panasonic cgr-d14s battery with cherry blossoms in the shooting. Choose a few have large aperture lenses DC, can yet be regarded as a perfect solution. Like Canon S95, panasonic LX5 such large aperture are both DC can more conditions. If you want to travel in the flowering Japan, enjoy flower in Mount Fuji feet, choose to carry such a small camera can be more outstanding portability advantages.

Choose scene is the key to success

Unless you are shooting cherry blossom festival live reports photographer, or shooting cherry blossoms choose when the main scene a large number of visitors to avoid by all means is to be in your photo role. Although perhaps the scene it's hard to do, but must try to choose relatively clean concise local background frame, so that the audience will put all the attention on your shooting on the cherry blossom. If it is hide not to open the condition of the population, Yang shoot is a good compensation method.

Many friends will choose in shooting taken sense the most beautiful scene. But we know this place is often we look around, their complete place oneself in the cherry blossom closed in the scene. If shooting at this time, it is very difficult to show when we see, because "blinded in this mountain". So when we enjoy flower to place oneself in the bears, the shooting scene but should as far as possible big free from outside the bears.

Of course the cherry blossom when shooting also can't always blindly "silly" pat cherry blossoms and sometimes it is to find something that can reflect the environment, the background or add photos panasonic cgr-d16 battery account the lasting appeal of background. For example a cherry blossom is the antique after a corner in the eaves, or a cherry tree after a hazy beauty figure can be different pictures of the pen that nods eyeball.

Good photographer must be a good light

The light is the most commonly used photography taken out method, the shooting cherry blossom is no exception. The light can be shot faithful records of the cherry blossom quietly elegant characteristics, in the sky as the background to the "blue" blue sky will better show it. But if all photos are the light shooting unavoidably "flowers to one side," seen too much the same type of photos after will visual fatigue. So for this to take many opportunities, we will do more to try.

Cherry blossoms flowers dense, the characteristics of beautiful form is not obvious, actually not suitable for light shooting. But the flower petal is very thin, and the optical sex is good, if during the filming a scene with big shot can make light of the Oriental cherry and clap out against the background of the administrative levels feeling and dimensional feeling was strengthened.

The cherry blossom lighter color, if for the sky to add a bit of background can appropriate exposure compensation, like this can the cherry blossoms had taken the color and feel fully. If in dark grey wall or in dark scene as the background note that a little less exposure compensation, or cherry blossom will because a aeration and a glistening.

The artistic conception to through the composition of a picture performance

Cherry blossoms HuaCu usually very big, open a dense, so with some big scene performance is a lot of friend can choose perturbation method of composition. But the composition of avoid by all means "full", if things are blooming cherry blossoms hard to avoid can let picture lose focus and which is weakened. In the big scene full of Oriental cherry must have the pen that nods eyeball or have the appropriate stay white. This combination of primary and secondary more easily than composition and outstanding effect because of the cherry blossom exuberant.

And when using macro lens, then try to find some HuaCu smaller cherry blossoms shooting. Many cherry trees is decades old trees, in strong on the trunk of the will to grow new bud out new leaves. Such HuaCu usually small, very suitable for macro photography. At the same time HuaCu and panasonic cgr-d16s battery trunk or branch after combining composition, the texture of the trunk and branches shape can very good outstanding cherry blossoms HuaCu, provide it.

If choose scene in the ancient near cherry trees, can choose a cherry blossoms combining background building outline for composition. How to composition is about to see the specific conditions and building flowers to analysis the outline, photographer, taken from the of primitive simplicity to atmosphere.

Three little skill set you apart

If can reasonable use of the above all the skills, trust that you can take pictures of a satisfactory. But I think a lot of perturbation friend will be hoping that small make up again on to some exclusive they, for everybody clap a different picture. So often focus on IT168 friends blessed, because these people they generally I don't tell him.

They one: the play around

Spring is coming, the cherry blossom trees around certain there will be other trees, flowers, like background, we can borrow these background and cherry blossoms together "photo", such as the picture color and rich content. Just be careful not the panasonic cgr-d210 battery sauce is better than the fish.

They no.2: combining static

The spring breeze of the stroke will pick cherry blossoms. The branches of the cherry blossom in spring swaying gently, and drew out new bud trunk often don't will be the wind blow. If new bud as the main body, the swaying flowers as the background, again complementary with slow door shooting, combining static effect is really let a person shine at the moment.

They # 3: side performance

Although we to shoot the cherry blossom, but also do not completely taken with cherry blossom as main body. If be able to some other more interesting points as the main body and object shooting with cherry blossom as a background, actually showed more spring in the air. Side also to show the cherry blossom for all things appeal.

With the popularity of digital products, camera early has become a common practice of the media, and, besides became people watch the carrier of the world, but also made a rising industry: freelance photographer.

With the progress of The Times, the photographer also like to take up have generally pleased, especially in recent years, a lot of people known as "independent photographer, freelance photographer", the title panasonic cgr-s602a battery seemed to be full of mysterious and inviting ray of light, in this materialistic s, sends out its unique charm. Many people joined the ranks of the free photographer, let this group is full of vitality.

4 months of Beijing, is very busy, the third pasture, the opening ceremony to photography season three shadows photography art centre at the church, and at the same time, the fourth submissions lasts three winners on also announced, young photographer ZhangJin with its pure manual photography won the three submissions lasts, a prize of eighty thousand yuan. Two other photographers drench, YangYuanYuan king won this year's respectively Japanese shiseido excellent woman photographer award and the us, foundation, a scholarship. In the three young photographer, two of them is "free photographer".

In the online I see the reporter interviews ZhangJin, he said "has always insisted on his three years without work, just according to traditional handicraft way to do the photography, the winning can finally get myself to do the things they want to do more." Don't know why, see this sentence, I felt a sudden sadness, I sad is not his success, but the process behind success. For three years, ZhangJin is a success, but many and ZhangJin in silently as do the photography, how are they going his own way?

In fact many people like the art of pure, pure photography, but really keep going, and can be successful and have several? Those who are free of hardship and all the way to the photographer, the end who can know.

The king to pour, because take a set of little-known stewardess works and get more people's attention, of course, but also to her as a freelance photographer, the road I'm afraid she had never thought of. Her this group panasonic cga-s004 battery of records daily life pictures of flight attendant state the clouds of tulip ", I think are able to win the prize for her to win so many honors, first is the theme of the uniqueness and confidentiality, a lot of people want to focus on is known for content, bring in the viewer in addition to get heart of that kind of to spy out outside, is also a kind of violence from the psychological!!!! Because this piece her famous, of course also got himself into a lot of trouble, lost work, also made a lawsuit, so "free photographer" named in her body is pretty heavy should! She said your current job is photography, no other, I can't help for her concerns, the future of the way this how to go?

Along with the traditional media economic conditions worsened, and freelance photographer this career is facing more and more challenges. They have to bear the pictures of the travel expenses and boarding fee. If not the media buy is white pat. Although good condition, there are still quite a few freelance photographer for the ideal and insist, the current domestic or foreign or fighting for many people, of course, now also have a group of people have come out, including the public eye was the hot photographer: LuoDan, LuYanPeng, tower, and so on, their works because the images style and the uniqueness of the present, and make some collectors become one of work favour,panasonic cga-s005a battery but many young photographer's work, or is difficult to get into the ranks of the market, the way of the future will take a long time to go.

Of course also someone will say they just in the pursuit of pure photography, art is to creation, such person is not not, but it really is scarce. Materialistic s, many free photographer in silently doing what I feel like things, will face a real test, who don't want their works were a fancy collector, who don't want to be the real freedom photographer?

processes

CPU power supply is the main CPU work is an important condition, mostly by power supply IC, mosfet, inductance coil, capacitance and other components, sometimes add voltage stabilizing diode, triode CPU power supply of the road.

The computer motherboard motherboard after electrify, power IC (also called PWM Control) began to work, a pulse signal, make two MosfET turns conduction, when load voltage at the ends of the VCORE (such as CPU necessary voltage) to reduce, through the MosfET MosfET switch function, external power of L2 inductance to charge and to the required rated voltage.

When the load on both ends of the voltage rises, through the MosfET MosfET switch function, external power source supply disconnect, inductance L2 release just filled with energy, then the L2 inductance acer aspire 1690 series laptop fan becomes the power to continue to load power supply. With the inductance of the stored energy in L2 consumption, on both ends of the load voltage gradually began to reduce, external power through the MosfET MosfET switch function but also want to charge. By analogy in constant charging and discharging process line becomes a stable voltage, always on both ends of the load voltage not rise will not reduce. Power supply figure as follows:

Note: this circuit as the Pentium Ⅲ motherboard is often used before, the general output CPU core 2.0 V power supply, the nuclear power supply 2.5 V, the kernel power supply 1.5 V, memory 3.3 V (also have chipset, occurrence in this way the power supply).

Circuit principle

CPU single-phase power supply circuit principle explanation: ATX5V after Lin added to the 25 th D of extremely, 12 V merits directly added to HIP3021 capactance filtering the Vcc, right now HIP3021 started to work, and through the internal oscillating circuit rectangle pulse signal UGATE and LGATE respectively by the output control the 25 th and Q2 G extremely; When the 25 th received acer aspire 3000 series laptop fan control signal after conduction, and to Lout1 inductance charging, when Lout1 charge to the rated voltage 2 V around (different grades of CPU) when the 25 th, Q2 conduction, inductance Lout1 discharge output to the CPU core voltage power supply.

When Lout1 inductance discharge less than 2 V, Q2 deadlines, the 25 th conduction once again give inductive charging; Through the 25 th and Q2 take turns conduction control Lout1 output a constant voltage supply the CPU. When we plug in A CPU, the VID0-VID4 recognition to the CPU internal level set, through the HIP6021 internal A/D analog-to-digital conversion, again through the comparator more control of the 25 th and Q2 of empty than can be adjusted for the normal work of the CPU output voltage.

POWERGOOD for power signal, when the CPU power supply normal when this signal CPU and began to work.

FB for feedback signal, feedback circuit monitoring output voltage and current is not beyond ratings, IC through feedback circuit feedback signal adjustment back internal control circuit, control the 25 th and Q2 for than empty, and always maintain the output constant voltage and current supply the CPU.

Maintenance processes

The first performance of fault for: CPU core voltage (Vcore) not normal. And this have two kinds of cases:

A, CPU core voltage high or low

1, high voltage check whether the 25 th breakdown or check feedback circuit.

2, the low voltage check Q2 breakdown or capacitor leakage and short circuit.

Second, no power supply

1, the first measure the 25 th D very 5 V is normal or not: if not normal ATX 5 V acer aspire 4710 series laptop fan will repair to the 25 th D between a circuit (usually few bad) if normal will continue the second maintenance steps:

2, check the 25 th G very control waveform: if normal to be need to replace the 25 th and Q2, if not normal will continue to the third maintenance steps:

3, check the power supply IC 12 V power supply: if not normal changes the 12 V power supply insurance resistance or check to the line between ATX12V IC, if the normal will continue the fourth maintenance steps:

4, check VID0-VID4 circuit, if not normal will need to replace 5 V and exclusion or related monitoring chip, I/O, buffer. If you continue to normal fifth maintenance steps:

5, and check around IC circuit: if the normal is acer aspire 5100 series laptop fan replace the power supply IC, if not normal changes the OCSET related capacitance.

Experience tip: general kernel 1.5 V and outer core 2.5 V not normal mostly for the voltage output voltage mosfet or the damage.

Night scene photography including many ways, is mainly refers to the outdoor lighting or shooting in the night of the object under natural light, it with sunlight lighting conditions and flash shooting method and effect are different. Night scene photography is the main furniture and shown around the original environment itself light, the light of fire, the moonlight, main light source, with the natural scenery and buildings and people activity of picture to shoot. Because it is in specific environment and conditions to shoot, often samsung sc-d29 battery gets some objective conditions and bring some of the restrictions shooting difficulties, so the night photography than daytime photography much more difficult, but it also has its own unique effect and style.

A day and night photography and different features:

1, lighting (or the light, moon) of the dual role

People in the night activities, always with lamplight, the light or moonlight as main light source, the light, the light and the moonlight night scene photography in addition to the light source for the role, and another function, or is part of the picture is composed. If a performance at night pictures of scenery, picture no light, the light of fire and moonlight appear, and light has light, the light or moonlight illuminate objects, that will make the atmosphere of the night abate, makes the picture lose its sense of reality. Such as shooting pictures of holiday fireworks, fireworks itself color and brightness on the picture, is not only an important part of the subject, and make the ground the outline of the buildings on show. So, fireworks serves as a dual role.

2, to live essence thick

We speak to thick live essence, not a picture of the photos things you don't need to move off, blocked or artificial processing decorate, but use the night light and shade very natural and the ably some damage something hidden no picture off. For example some desultorily scenery, unable to avoid off during the day, in the night scene photography can deal with it, such as shooting a site, often messy things during the day many could not avoid and directly affect the picture or composition beautiful wait for, but in the night shoots, these obstacles can use against picture lamplight illuminate, the need to things in the picture of the outstanding above, do not need to object to avoid light will it subduction in the darkness, take these tactics, filming than day is much better.

3, exaggeration scenery, add atmosphere

Because at night shooting has its unique shooting method and special processing technique of the picture to exaggeration scenery, add atmosphere the secrets of the technique, the so-called exaggeration scenery, is about to picture needs highlight adequately, will some beautiful scenery concentrated expression comes out. The so-called add atmosphere, that is, make full use of the surrounding environment, will be rendered scenery, in to a reasonable exaggeration, foil theme. Just to take a road as an example, the day seems many vehicles, but to live on a photo of the vehicle is not much, the reason is what we see many vehicles is in a few seconds or minutes on within the impression, the effect of course and auditorium impression is not consistent, but in the night photography, can play the night photography specialty, with long time exposure method, let the traffic lights of the photographic film many times, and makes the picture appears on the front of the line article innumerable lights, thus make vehicles, and the effect of heavy traffic, so reasonable exaggeration and render help to the theme of the outstanding.

4, is suitable for the rest of the shooting scene

Because the light night photography is very weak, than sunlight difference is very big, even some light as the scenery often even level could not see that in this light shooting, the samsung sc-d303 battery exposure time is extended. So, take very appropriate shooting at night not action quick objects. On the other hand the night radial light and shade are very different, bright place very bright, dark place is very dark. As in a driveway street lamp light due to limited range and by light and not divide evenly, if use fast speed exposure, not only to avoid the waning light caused by inadequate exposure of the near and far, increase the picture level, the exposure time now that extend, taken to the scene will be required in a certain time don't move, just may clap a clearer picture of the layers of the night.

5, tonal for a strong

Night photography, due to the limited by light, not can photograph line careful, rich administrative levels scenery. Such as shooting of a person's facial expressions, or filming the detail adornment such as decorative pattern building, is the more difficult. For a few lights, a few lines combination, the outline of the outline of the distinction between the buildings, the character of appearance score, black and white processing, light and shade contrast and so on, it is suitable and appropriate. Due to the above factors, on a night of photos often give a person to screen is black and white, tonal contrast strong impression.

Second, scene features and environment, Angle choice

Night shoots, every scene has its unique and other objects of different place, these different landlords, and some of the environment and conditions around inseparable, and up for each other, the function of mutual echo. Then make the scene itself more remarkable characteristics is outstanding, these features is often shown in the contents, forms, the scale, geographical environment, climate classy every aspect. To catch the characteristics, sometimes must first understand the interior of the subjects, those are the main, and those are secondary, and activities such as law, below are listed several scene in the night when photography between effect.

1, lighting (or moonlight)

Lights (or moonlight) often is an important component part of night, it is also the night scene photography main light source, and no lamp or light scarce, the body would not expression comes out, or performance is not clear. Have enough light, not only can make physical present level, can also makes the picture more bright and clear. Flow of lights (car light the lamp, ships and other moving light), can present a light on in the film (namely column), can make the content add atmosphere, the picture get better effect.

2, rainy day, foggy weather (or damp weather)

On rainy days, fog lights can be in the photo beautiful aura, the sky is tonal as the air by the influence of water light, sometimes also can reflect the other color and appear on the picture, if use CaiSePian shooting, the effect is more apparent. Because of the rain asphalt or smooth ground, can show the object and the reflection of light, the effect of clap out more vivid.

3, water

Water at night sometimes to have certain effect. The sea, rivers, and ponds of the building. Because of the water reflective reflection function, it can make the shore or the light around to increase brightness and a scenery line outline, smooth shadow, can add a lot of angry to picture.

Night shoots, and master the characteristics, choose perspective and the use natural condition are closely linked. In other words, choose according to photograph the object must be Angle characteristics and the scene of the natural environment and calm, and master the characteristics, choose samsung sc-d305 battery Angle, the use of natural environment all three parts of the subject must obey the request, is not alone.

The stand or fall of choice Angle, to the performance theme, highlighted its characteristic also has very big effect. For example the project scale great site performance at night, useful high Angle is better. Performance of building large, majestic, used the low Angle is relatively appropriate.

Choose Angle, and they should pay attention to the camera position, be in usually, sunny day night sky is the west east bright black. From the east to the west, water is a piece of white, water and the sky light glance no much difference; Look from west to east, water reflection ability is very weak, a gray color. In the evening at night took from the east to west taking lens effect is good, but in the opposite direction taken by dawn, the effect is good, such as rain or a cloudy day, but don't have to consider these issues.

Three, the night view of photography exposure

In the process of photography, exposed correctly or not, is photography technical success or failure of the key problem, so in this step work, must be taken seriously, cannot careless finishs STH, to careful accurate. So, must according to different scenery, different light and the theme of the different requirements, to determine the time exposure. At night, the exposure photography can be roughly divided into two kinds of methods, namely a exposure and exposure times.

A exposure, is the camera on a tripod with a good, and then through the viewfinder shall be taken of the scenery, as requested, arranged in the picture. Take after ning, the camera on the tripod fixed, not make its activities. Filming, use the shutter release control shutter open or close the (or with lens cap control has open shutter) on a proper time exposure.

Many exposure, as well as the operation process, just exposure is not a complete, but in the same piece of negatives, through two times more exposure to finish filming.

Many times in a exposure exposure is not finished making the work can only use a kind of method, if conditions have (light, samsung sc-d307 battery environmental conditions, such as time all match requirements), a exposure is most ideal. But sometimes in order to get some kind of special effects, and many times the exposure, and in every time exposure--some scene is needed. In filming, we should pay attention to the following aspects:

(1) in the master exposure, can put the light intensity scenery such as separate, make the dark scene first exposure, much exposure, the brightest is less exposure, after exposure, and this can make up for exposure uneven phenomenon.

(2) meet certain scenery, when the first not in photographic exposure or more exposure, may be the employing work to subsidies light, dark scenery of light on subsidies, make contrast weakened.

(3) some scenery because the light strong or weak, cannot avoid in filming, first took later, in large still can use to keep out correction.

No matter use a exposure or exposure times, to master the accurate exposure time and the choice of appropriate exposure time. In general, the night of photography in a second exposure time above, general by a seconds to a minute, some special circumstances also have exposure for several minutes, filming will depend entirely on the photographer, the control. If excessive exposure, the light itself because time is long, will be around to spread, of the surrounding buildings or the sky produce large white, increase contrast, will like this broke the night scene lighting effects.

Exposure is insufficient, the photograph also will have adverse effect. Can't tell scenery outline, no levels in the photo in addition to the lights, the rest of the submerged in a dark in the picture, taken in at night, if the sky and some rays (in the evening or early morning), want to be careful to make the sky photographic shortage, don't make photographic peak, otherwise will lose the atmosphere of the night and characteristics.
