A/AV aperture priority model and fuzzy control clear

Aperture priority was to Camcorder Battery manual adjustment aperture size, and then to use the camera for the shutter obtain values. Due to the size of the aperture directly influence the depth of field, so in the daily photographer photography, this model is most widely used.

In the film, like, we generally USES large canon bp-808 battery aperture and get a long-focal-length throw the background is for the shallow depth of field effect, this shooting style can highlight the main body.

During the filming the landscape, the photographer generally want to get broad, the vast expanse of the visual effect, in order to make on the photograph was taken all objects are completely clear, the space feels clear, needed to use the F22 or smaller aperture value.

Aperture priority of the main significance is to control the picture of the depth of field. We all know that picture of the depth of field by the canon hf10 battery aperture of the lens size, the focal length of the lens and take distance to three factors, while filming a photo, the focal length of the lens and take distance are certain, can use the only change the size of the aperture, therefore, aperture size on the picture of the depth of field in fact plays a decisive role.

Use aperture priority should also pay attention to look through the viewfinder display shutter speed. When the subject the strong light, and you chose the maximum aperture and shutter speed and more than the actual camera canon nb-2l battery shutter speed, can appear excessive exposure, should narrow aperture shooting, when the subject field light weaker, or are you in use small aperture, is the opportunity to choose slower shutter speed, at this time you choose if is armed with shooting, so picture is likely to appear the fuzzy, influence the picture quality, you can choose from a large aperture is to use a tripod or to take photos.

According to the composition of the shooting travel photography skills

Tourism memorial as shooting, should according to the Digital Camera Battery surrounding environment and site conditions, adopting appropriate composition methods and skills.

Did picture composition. Banners in the CANON NB-1L Battery filming of tourism as composition, can highlight environment in a beautiful scene, can accommodate more people and the content of the scene. A general picture composition more suitable for shooting bust or features, outstanding character.

Box type composition. Use of field of the door, window, frame composition form called box type composition. In the scenic spots, the characters in "box" for these, can increase the picture of depth and stereo feeling, and more novel in form. The box type composition, had better use the dark border scenery,CANON NB-3L Battery so light color should be using backlight photography, the dark to border of the "dark" line of the main body of the "bright". Be used as the border with the main body of the scenery there should be some relationship, not derivative irrelevant border. At the same time frame is narrow unfavorable wide, otherwise is lost to decorate the effect. Of course, need to have a pair of composition, also found that "framework" eyes.

The triangle composition. Usually in the nature of the same three things, or view the composition triangle, give a person with stable feeling, has the extension and guide visual effect. In the actual composition, arrange the children in different positions of the picture, can make the viewer produce different lenovo, such as using CANON NB-2L Battery the scenery around for the triangle composition relations, more can show the different picture.

Use opportunely glare clap a beautiful effect photography skills

In the backlight photography to in front of a camera CANON Camcorder Battery under the hood, in order to prevent the glare and miscellaneous light into lens, so as to achieve a

clear picture of high quality, but in some cases, using the glare but it can get very special to take the result, photographs have a kind of special flavor.

Actually want to clap a beautiful glare effect is very simple, as far as possible let the position of some low model, the canon bp-808 battery position of the photographer high

some, this can avoid off too many strong light, keep only enough light to build the glare of the special effects. As for model facial brightness, can use a

reflector slightly for light, if all around shooting environment brighter, even can not using a reflector light supplement, only use environment of fill

light scattering the light from the sun, where you can get a higher brightness picture. And no glare compared the clear pictures, pictures of the glare of

less sharp sense, but many a kind of special dream effect, warm glare around in model created a blurred, mysterious feeling, is very attractive.

Just contact glare of photography novice might hand shake and cause canon hf10 battery failure because, this is because the model positive didn't get enough light supplement.

At this time, better use the tripod shooting, or raise the ISO GanGuangDu will shutter speed faster.

Use the glare of filming, try to get the position of the model of low some, avoid getting into the light of lens too much.

Use the glare of the sparkle of the canon nb-2l battery flare manufacturing blurred dream effect.

The performance of the quality of a material texture

Reality appearance condition CANON NB-1L Battery, nature of the object, and the accurate exposure and appropriate in light of the key factors in the simple sense is performance. The exposure of the strict control and correctly, can make the scenery of light and dark texture can be very good, and exposure to represent its excessive or inadequate exposure will make the object by the simple sense of loss, and at the same time levels can affect CaiSePian colour saturation.

The light lighting for things simple sense has important influence on the performance. Rough texture structure objects, like fur, grass, cotton products, trees, how wrinkled skin texture, etc, the surface is rough protruding sunken ups and downs, the photography CANON NB-2L Battery by side when appropriate light, the backlight lighting, can make the surface present a different light and shade of building, well reflect the rough texture.

Soft scattering light inclined side lighting, makes the quality of a material of rough surface structure and close the CANON NB-3L Battery pale green vegetation and damp smooth moss has the obvious differences and light and dark tonal contrast, the simple sense of picture effect would be got outstanding reappear.

Natural light top side lighting, the character of facial wrinkles, folding of the metope of clothing and rough texture can clear texture to characterize the out, remember years trace.canon camera batteries

Google Android pay application was forbidden Taiwan refund time too short

According to media reports, from Taiwan regulators in CANON NB-1L Battery command, the Google has decided to stop in Taiwan sales Android applications. Pay

Although this problem is not like it in the United States faced the federal trade commission's antitrust investigation so serious, but Google and Taiwan regulators must also have a CANON NB-2L Battery tough time. Taiwan regulators have been ordered to Google stop in Taiwan through the Android Martket pay application sales.

Google and Taiwan regulators problems stem from Android Market consumers to buy after application of about a provision of the refund time. Taiwan consumer protection laws provisions, online retailers must provide consumers of seven days time, and Google now a CANON NB-3L Battery refund for providing consumers with the refund time only 15 minutes.

The Taipei city government legal and regulatory commission in the subordinate earlier this year made the decision, that the above consumer protection laws provisions shall apply to Android and iTunes store, and require application Google and apple modify their CANON NB-4L Battery application store policy. Apple according to the request and change, Google it (or the rebuffed.

Google spokesman, Android Market to provide consumers with 15 minutes of the refund have enough time, the policy can help consumers make rational decision, at the same time also can let Taiwan developers effective management of their business.

Google would not refund will be prolonged to 7 days, but decided to temporarily stop selling paid in CANON NB-5L Battery Taiwan application. The move caused a strong dislike of the Taiwan government, the municipal government press releases, Google says published do so obviously wanted to put Taiwan consumers as a hostage, the purpose is for the privilege of not kept Taiwan law.

Legal and regulatory commission has to Google shall be fined not more than 100 WanYuanXin dollars ($35000) fine, the fine of reason may not because Google violates the law, but because it arrogance. CANON NB-6L Battery

The personage inside course with Google for Taiwan was a bit surprised by the practice of operation, because many manufacturers such as HTC Taiwan electrical and many other small manufacturers are closely related with Android, Android pop for those manufacturers is favorable. The personage inside course of study thinks, Taiwan may be to do so in the start of the new round of elections for voters, because protecting the canon camera batteries consumer rights support can be sure to government authorities to win some political points

The power of Canon Powershot digital camera

If you want a reliable and robust camera canon nb-2l battery that will last a long time, as well as provide photos that will also survive several occasions; record special moments of your life with excellent, crisp images that will last forever, so is the Canon Powershot the camera for you. With Smart Auto mode, you have the perfect setting to take photos.

The camera canon bp-308b battery will detect that you are trying to take a picture and then she'll make sure that all technical details are fully met, will take into consideration the color, movement, contrast, and all the available light. So even if you are visiting friends at the lake or watching a sunset breathtaking from the top of a mountain or looking at the flowers in the middle of a rainstorm, you will make sure that the camera will adjust to take the most lively, vibrant and beautiful images that you dreamed. The manual options are there, so you can also adjust the way you want to take pictures. You can choose between rooms inside, outside, night, fireworks and a number of other ways that allow you to get photos based on the environment, so the lighting is properly adjusted and your photo out wonderfully.

The 12.1 megapixel resolution, is designed so you can choose your favorite photos and have them in large prints with remarkable quality. No matter how you cut the picture, or how much you increase, it will keep the detail and quality enabling you to enjoy the images so sharp and clear. Suppose you use a Canon canon bp-808 battery Powershot to take pictures of a bride and groom or their new baby, thanks to high resolution and sharp, you can easily make great photo enlargements and have them hanging on the wall so incredibly clear and excellent quality, enabling you to keep this memory forever.

Canon PowerShot has convenience in mind, its system of 2.7-inch PureColor LCD screen has a clear picture, which lets you see exactly how the picture will look even before it was taken. You frame the shot the way you want it to appear on the screen and it will show the photo once you've taken. With durable, lasting quality, you can easily see what kind of picture is taking no matter the ambient light around you. Speaking of light, the Canon PowerShot has light as a principle, since light is an important factor for a good photo. So no matter what your situation ambient lighting, the camera canon hf10 battery has an ISO 400-6400, as well as a Low Light mode, which lets you take pictures even in the shadows. Even though the place is horribly dark, lit only with candles or lanterns or somewhere in a dark cave, you can still get great shots.

Filming the silhouette technique

There are some skills: shooting canon nb-2l battery silhouette under the backlight your eyes narrowed eyes, let into the main light decreases, will find subject formed silhouette effect and faster to grasp the shape of the silhouette. Also, when you take multiple silhouette of form, don't let silhouette, overlapping between may produce unless you're want two or more silhouette synthetic a new image, otherwise the silhouette might make overlapping who cannot distinguish original modelling effect, thus will lose silhouette of expression.

Silhouette language expression of subject peripheral outline more demanding, too simple or lack of expressive peripheral outline is not suitable to the way to show the silhouette. Because once smoke went to the internal structure, main periphery outline became the only force part. There For example, the silhouette portrait photography canon hf10 battery often choose the performance side of modelling, reason is character than positive side the outline of more features, side with smooth lines that shape between person and person produces quite clear distinction, and positive silhouette too simple and appear drab, it is very hard to distinguish between the two, this is should arouse the attention. Describe the vivid mudra, sometimes more than details rich that picture, let a person be interested.

The language structure is implicit silhouette, because the underexposed pictures subject constitutes a bottomless space, but as long as the contour vivid, everything is not in character.canon bp-308b battery

How to determine the appropriate exposure

AE

Now, all of the stupid camera CANON Digital Camera Battery and the vast majority of single-lens reflex camera (SLR) have an auto exposure (AE) of the available features. In theory, we have to do all the work is the lens at the subject matter, and press the shutter button. Built-in light meter will complete the remaining work, regardless of the color film or black and white film, it will automatically calculate the "correct" exposure. This seems to look perfect, but unfortunately the built-in light meter that "correct" exposure is often wrong!

Why? Because the light meter does not think, only we think. We want to correct the subject's face exposure, or do you want to only show the contours of the face and exposure for the sky to catch the beautiful sunset while it? AE metering system can only guess is that we want to get the object, no matter how complex metering system, it is impossible to know what we want.

While we ourselves know what we want to do. This lesson will learn how to use the camera's built-in metering system and a separate light meter to ensure that every time we need to get exposure. We do not guess, but do not know.

The type of metering system

Basically, there are three different types of metering systems, we can find their own way out of its use.

First of all, you can use the automatic metering system. Such systems are generally used in the fool the camera, it can automatically do it all. We do not have any control of the exposure, the camera will complete all the work, but it does not matter right or wrong. If our camera and metering system is fully automated, without any control of our exposure, then they want us to do? Perhaps we can do nothing on the exposure control, and yet not be overly pessimistic. This lesson we will introduce some techniques, the use of these skills can "fool" the camera, and thus exert some control over exposure.

Second, we can use the metering system with built-in camera, it allows us to conduct a manual exposure control. Many cameras have auto exposure to manually override by a known way to achieve this function, that is, turn off the automatic metering system, and manual exposure control.

Most SLR cameras CANON NB-3L Battery offer a "model" option, which we can set the camera for a variety of different automatic exposure modes, you can also set it to manual mode, the exposure to full human control. Whether using a manual override or manual mode, the result is the same, that is, to impose artificial control of exposure. A third possibility is to use a separate handheld light meter, as shown in Figure 5.2. If we do not built-in camera light meter, you can use this separate light meter. Or we can use it to supplement the built-in light meter to get the data.

Regardless of the type of light meter, but also whether to take a color film or black and white film, the basic principle behind its operation is similar. There are two basic types of metering systems:

1. Reflected light exposure meter

2. Incident light meter

What is the reflected light exposure meter

Reflected light meter is more common to use all the built-in light meter are this type. The meter is the object of the reflected light is measured. When the lens at the subject at the same time, it will be the face of optoelectronic components of the subject.

The alignment meter, the brighter the subject matter, which gives the higher readings; are aligned, the brighter the subject matter, which gives lower readings. If the meter object aligned with a mixture of the composition of light and dark scenes, it gives the average brightness of the whole scene, whether it is to take a color film or black and white film, readings are the same.

Theoretically, we may we are interested in the subject is arranged near the center of the photo CANON NB-2L Battery , so some of the built-in camera light meter will be more concerned about the image near the center of the reflected light, and more less attention to objects near the edge of the reflected light. The meter is the center of focus for metering, that is, they produce a reading of all light in the scene based on the strength of the center of the light is particularly emphasized (weighted) and obtained.

Another type of reflected light meter is a spot light meter. The meter reads a very narrow region of light - may be only a twice wide. As the name implies, can point to the spot meter and read a very small spot. Therefore, some SLR's CANON NB-1L Battery built-in light meter that offers a choice of local metering function.

Today, many of the most complex camera offers a feature called Matrix metering. In fact, these cameras is the frame into different intervals, such as a central range and angle of the individual interval. Meter "reads" the light in each section, and the information is fed into computer chips, the chip is given in the light of each interval, and the information is fed into computer chips, the chips are given for each reading " value "and ultimately determine the" correct "exposure. However, this meter is still only guess our intention, as we mentioned in the previous example: we want to correct exposure is the subject's face or sunset when the sky? Meter can not make decisions for us.CANON NB-6L Battery

What is the incident light meter

The incident light and reflected light meter light meter is different from the camera CANON NB-5L Battery position is not to point the subject is, but from the subject is at the point the camera. The result is exposure to light the subject is on the light meter will fall on the same token, this is the light that we are measuring. We do not measure the subject brightness value of the object itself, but the measure fell on the subject is on the light. Meter designed to indicate the correct exposure required for exposure, and assume that the scene from clear to dark tones, the average range.

Should use what type of light meter

Incident light meter in the professional photography has a special value, for example, used to balance studio lighting. Now, we recommend using the light meter is the type of reflected light. Remember, the camera's built into us as the reflected light meter light meter, so we can safely use, as long as we understand it the flexibility to use it.CANON NB-4L Battery

How to handle the color balance DV camcorder

As technology advances, the development of the camcorder CANON NB-1L Battery tends to size small, functional automation and price is reasonable, while the television camera has quietly entered the people's entertainment. Television camera into people's lives not only enrich people's entertainment, but also to pursue more artistic people ... ... People often talk about the color screen does not reddish to bluish, the appearance of the screen. In fact, the color balance is a television camera is one of the important technologies. Here, I want to take the Sony DCR-TRV27E camcorder, for example, on how to correctly handle the DV camcorder's color balance of a point to talk about their experience and understanding.

Color CANON NB-2L Battery is one of the means shape the TV screen, it has a direct role in human vision, gives rise to emotional responses. Color screen, a direct impact on the quality of TV programs, how to correctly handle the color balance of the TV screen it is very important. Correctly handle the color balance of the TV screen has two meanings: the TV screen should be properly restored the natural color of the scene, no color cast; from a deeper level point of view, the color television picture and television should be to convey emotion and mood is consistent. In this article, because of space limitations only talk about the first point.

"DV" is the "Digital Video" acronym. DV video camera CANON NB-3L Battery is the digital camcorder. According to the different features and price, DV camcorders with home video cameras and professional video cameras of the points. Home video cameras and professional video cameras compared to the color balance in the regulation of the screen when the camcorder does not have manual white balance function, such as DCR-TRV27E only 4 white balance mode Hold, Indoor, Outdoor and Auto, but also Some DV camcorders only one white balance mode Auto. For professional cameras, the color balance in the pre-shooting machine improperly can take advantage of post-production effects in the appropriate remedy. For weddings and other family tourism and entertainment video, it does not have these conditions, once the shooting, when there is no way to make up. This requires shooting to correctly handle the color balance.

Here's the DCR-TRV27E camcorder,CANON NB-4L Battery for example, to talk about the correct handling of DV video camera color balance method. In the above-mentioned DCR-TRV27E camcorder white balance adjustment is usually only 4 ways: Hold, Indoor, Outdloor and Auto. Their usage is different.

One, Hold

Shooting an object or background color, usually white balance using this method.

In the following cases, the white balance set to Auto, and after a few seconds to re-set to Hold.

Change PROGRAMAE way; the camcorder from indoors outdoors, or vice versa.

Second, Indoor

"Indoor" in Chinese means "room", but does not mean that all indoor shooting are a way to use it. It depends on the indoor illumination conditions. Because the television camera in the room is usually carried out with tungsten lighting, so the true meaning of Indoor indoor shooting is not to say all this way, but rather for the 3200K color temperature of light. So that did not play lights in the room but from the windows or doors shining, the light source color temperature is 5600K, can not be used this way, but rather use the Outdoor mode. So be sure to understand the Indoor 3200K color temperature light source refers to the white balance mode.CANON NB-5L Battery

Here are some ways to use the situation Indoor White Balance:

1, in the room, to tungsten, or incandescent light sources as the main shoot.

2, the sun rising or falling quickly when the sun, the sun color temperature close to 3200K, at this time, it should be used in Indoor. If the sun rises over the horizon or the sun disappears below the horizon, you should use Outdoor.

3, cloudy or night outdoors with tungsten or incandescent lighting for the main shoot, they should be used Indoor white balance mode in order to obtain the correct natural color.

4, sodium or mercury in the shooting.

Third, Outdoor

"Outdoor" in Chinese means "outside", and are usually shot outdoors with the sun, so, Outdoor actually refers to a color temperature of 5600K white balance shot way of illumination.

Here are some selected cases Outdoor white balance modes:

1, in the outdoors, sunlight as the light source to shoot.

2, the sun has already risen in the morning or evening sun on the horizon, not down the horizon, the sun color temperature close to 5600K, should be used in Outdoor.

3, fluorescent colors in the room to shoot as the main source.

Fourth, Auto

Auto white balance adjustment mode is automatic when the light source or lighting conditions change the camcorder automatically adjusts the white balance. In most cases, the proposed use of this white balance, the general picture can be a good color. The following situations for use of this White Balance:CANON NB-6L Battery

1, the light mixing occasions. If both the sun, there are lights, then the best way to use Outdoor;

2, color temperature changes quickly in the light of the occasion, such as the shooting party stage lighting changes quickly, preferably Indoor.

Remind beginners to note that after the replacement of lighting conditions, shooting situations tend to change, then we should pay attention to timely adjust the white balance mode. Such as weddings and often from indoor to outdoor, and then back inside, shooting will identify the appropriate white balance mode. Often change the situation in the shooting venue, it is best to use Auto mode, adjust the balance so as not to forget the hectic way.CANON Battery Charger

Talking about the popularity of DSLR brief history of digital SLRs

The first digital canon mv750i battery single lens reflex camera (DSLR) as early as the early 90s in the 20th century has been available, but not until 2000 that the camera began to widely proliferate. Work only a few short years, digital SLR users have been relatively few photographers news and public relations to the majority of the development of professional photographers and amateur photographers. This huge leap on the one hand due to sensor design and digital storage of significant progress, since the main camera on the other hand is the fierce competition among manufacturers, making the camera specifications rising costs continued to decline.

Until recently, trying to film to digital photography who also face the question: When will purchase the largest investment the minimum income? Rapid technological progress, the previous week's top high-end camera to become obsolete in the next week, nobody cares. But how much this situation has now eased; presented with progressive advances in technology, rather than revolutionary, the magnitude of price cuts has slowed. Technology is mature, all forms of digital photography - especially digital SLR photography - ushered in the first spring, people began to be widely accepted and loved.canon nb-2l battery

The dawn of the digital age
The late 20th century, 80, appeared in the first scanner, image processing software and the ability to take these powerful computers, the digital photography era began. At the time, is still photos taken with film, and then through a scanner to do digital processing. The computer equipment was extremely expensive (by today's standards look very low-level), thus the early use of the equipment of almost all the world's top newspapers. News publishers on the one hand in the endless competition with each other, trying to grab the opponent in front of sensational posted on the front page news, but also do everything possible to make the production system have been eliminated to achieve modernization. In fact, when they have begun writing for the computer design and layout, so no matter how high the cost, they use the computer sooner or later, armed with this aspect of photography.

Almost at the same time, digital capture images - that is, take a picture with a digital camera - start coming into view. At first, this film is very clumsy way. Early digital cameras can not handle the image and thus have been connected to the computer. To obtain color images, the need for exposure of the same picture three times, respectively - on the red, green and blue of the exposure time. In this way, shooting moving objects has become unnatural, but also means the camera when taking pictures must be firmly fixed, to ensure that the exposure between the two can not have the slightest move. This camera is severely limited by the use of only applies to studio still life photography.canon bp-308b battery

Digital SLR debut

These problems are resolved early, first of all, thanks to a single exposure to the three primary colors by capturing all of the new camera. Then appeared not connected to the computer models. In 1991 the first digital SLR camera marks the birth of a huge improvement. Developed by the Kodak camera, code-named DCS (later renamed the DCS100), is the world's first truly portable digital photography equipment. It is based on Nikon F3 body and the design and development, with universal Nikon lens is 35mm photographic camera people already familiar with, but less negative position, replaced by a digital sensor and a number of related electronic components.canon bp-608a battery

The device has numerous drawbacks inevitable. The camera can not store images, image transfer to go through the connection to the digital storage unit (DSU) to go, and photographers who like the same back carrying a heavy backpack digital storage unit. Second, the size of the sensor than a 35mm film to be small, so not all cover the lens field of view, the resulting focal length conversion factor of a say (now many digital SLR still the problem.) Another point, the image resolution for power and dynamic range (shadow and highlight areas of the resolving power) is also far better than the film can play a level, the sensor can be only 130 million pixel images - much better than the current mobile phone with camera pixel is even lower.

After several years, Kodak has introduced a number of consecutive new digital SLR, the DCS100 steadily with development. Most of these models using the Nikon body, there are some from the development based on Canon body. Technical content has slowly improved, but prices are still astronomical, high, according to models of different prices in 10000-25000 pounds (17000-42500 dollars) between the float.

Newspapers and news agencies played a pioneering role once again. Magazine photo paper printing photo quality demanding, and printed in the newspaper some of the standard will be relaxed. Newspapers, the transmission speed is critical draft, so the phasing out of the DCS series of cameras with longer time-consuming, to obtain images by scanning the negatives for the newspaper republication of the old method. Still later, a photo shoot after a few minutes with a laptop can be reached by e-mail before editing, digital SLR photography has finally received the news supremacy.

In 1999, Kodak and Nikon the two companies parted ways, digital technology accelerated the pace of progress. Nikon will soon be announced that it is developing its first digital SLR D1, the price of any one of the Bike Da are much cheaper. Fujitsu followed suit with its cheaper Finepix S1. 2001, the Canon D30 carrying join the fray.

Since then, there have been new digital SLR market, prices dropped lower and lower, configuration, continuous improvement. Computer is essential to any extension of a digital SLR since 2000, the computer's processing power and memory configuration has a leap forward, pushed the technology of digital photography to mature, and easy to use. Kodak - the great pioneer of digital photography - has been left in this race to the back in the end sadly retired in 2005.

A brief history of digital SLRs

1991, Kodak launched the world's first digital SLR DCS100.
Then in 1992, Kodak launched DCS200, which is the world's first with built-in image memory (a miniature hard drive) of the camera.
1994-1995 developed DCS420 and Kodak DCS460, made in the design of major improvements.
Kodak 1995, ushered in the first batch of competitors: the Nikon and Fuji teamed up to launch the FujixDS-515, and Minolta RD-175.
1998 Kodak DCS camera the other three asked the city: 520,560 and 315. Prior to this, DCS series cameras all designed based on the Nikon body, while the 520 and 560 for the first time using a Canon body.
During the 1998 World Cup proved a news photographer dominance of digital photography continues to strengthen its advantage in the constantly expanding.
Nikon 1999, Kodak released the fuselage with DCS620.
1999, Kodak and Nikon collaboration rupture; Nikon developed its own digital SLR Nikon D1, Kodak DCS series of prices is equivalent to a small part of the camera.
2000 Sydney Olympic Games, once again proved its digital SLR photography and news photography in the field of sports dominance.
In 2001 Canon introduced the first digital SLR (D30); Nikon broadens the product range; Kodak DCS760 into the market.
In 2002 Kodak introduced DCS Pro 14n, known as the world's first full-frame sensor with a digital SLR. However, the camera did not meet the standard of pre-publicity, followed discredited.
2001-2005, the main camera manufacturers have released a new digital SLR, the price plummeted, technical content rapidly.
Kodak 2005, tragically lost in the competition, announced the launch of the digital SLR market.canon bp-412 battery

how to make the picture more clearly

Photography CANON NB-1L Battery, the focus clearly is the basic requirement, but for beginners, requires a clear focus of each photo can have a certain degree of difficulty. Many factors affect the focus of a clear, if you can not have a good grasp, it is difficult to obtain good results.

Here are a few good way to keep a clear focus for beginners reference.

1. To prevent vibration. Vibration would shake the image in the blurred photos, even if the focus is very accurate, and will therefore affect the imaging and clarity. Vibrations generated are generally two reasons: First, the camera shake, that is, press the shutter, the camera shake caused instability in the control. Second, the main movement, that is, the moment the camera CANON NB-2L Battery shutter open, your subject is in motion its own, but short enough shutter time, did not freeze live dynamic, so the situation appears blurry.

To prevent vibration, must be the right medicine, you can take measures three aspects:
(1) camera CANON NB-3L Battery mounted on a tripod. If by the shooting conditions, can not support the tripod, monopod can also be switched.

(2) shortening the shutter time (generally use 1 / 250 second), can reduce the vibration generated image camera shake.

(3) The correct way of holding machine. In the case without a tripod, holding the correct posture machine or not, will directly affect the stability of the camera CANON NB-4L Battery.

Your subject themselves to overcome motion blur, only one way, that is to shorten the shutter time. As long as conditions allow, the shorter the time the shutter the better.

2. Not one-sided pursuit of a small aperture. Beginners that small aperture will increase the depth of field, must make the image clear, therefore, regardless of where they tend to charge very small aperture, especially when the focus is not sure, but will believe that a smaller aperture can be of help. But the final results do not always ideal, because the use of small aperture will result in the shutter time and, therefore, the camera shake to produce enough negative impact. Therefore, one-sided pursuit of a small aperture is not the best, the correct way should be to use short shutter and tripod.

3. Proper understanding of the characteristics of the lens. Many people believe that the more the lens aperture with a small knot like greater clarity. This view is not correct. In CANON NB-5L Battery fact, the best imaging lens, the maximum aperture is reduced to 2-3 after block. If a maximum aperture of F2.8 lens, when the aperture to close at F5.6-F8, the end like the best.

4. Note contrast between King and subject. Subject and the color contrast between the lining King size, it will affect people's vision, the focus remains unchanged, the main contrast between the King and the lining of large, high-definition video looks appears; if the color contrast between the small image CANON NB-6L Battery to see up the resolution is low. Therefore, to make the subject in the picture is clearer, a conscious choice to high contrast lining King is very effective.

Shooting skills in the water

The performance of many forms of water, including dew, ocean or river. So how do you come to shoot different subjects, in which the exposure time and play what role? Here you can learn the appropriate knowledge.

Water features rely on movement, surface reflection and reflection to the performance, which makes the corresponding shot is not too easy. Tell you how to use the right technology perfectly capture the water and use some "tricks" to create a completely different atmosphere.

Exposure time on the picture plays a decisive impact on the atmosphere: a short exposure time can be instantaneous movement solidified. This camera can capture the moment the naked eye can hardly notice. Even as the glass in an overflow or a water column of each small water droplets, can suddenly appear.
What kind of exposure you need time, which must be taken through a number of experimental determined. Long exposure time can produce the opposite effect. The longer the exposure time, motion blur becomes. For example, you can use a long exposure time to capture a mysterious stream. Using a long exposure time of the case, we must use a tripod. The only way to ensure that photographs did not shake. Using a tripod Another advantage is that you can focus on the subject, determine the size of view and consider the reflection. When shooting in hand, the exposure time should be longer than the reciprocal of the focal length. For example, you shoot using 60mm focal length, the maximum exposure time can not exceed 1 / 60 sec.

Reduce the image elements

Reduced by reducing the depth of field and shooting range, dew on the photo placed in the center. Only one was really clear record of dew down, the leaves and the background are integrated into in a blur. On the camera you select the "Macro mode" in order to bring the largest possible format dew to shoot down. As for the subject matter you can go and how close shot, depending on your camera in macro mode provides the kind of close-distance, as shown above.

Create fuzzy

Clear stones and rushing water create a collaboration between the understanding of the movement. To get the motion blur effect is very strong need to use 2 seconds or longer exposure time. To do this, you have to "shutter priority" mode (Tv), select the exposure time. Then, the camera will automatically calculate the appropriate aperture. Clear position will appear in fixed places, this can be the stone river can also be a bank. If your camera does not "shutter priority" mode, you can also choose "landscape" mode. In this scene mode, the camera will choose a small aperture, so that at least can get a longer exposure time

Change the color of the water

Use of white balance, you can set the color tone fundamentally. When the white balance in the "light" option, the colors in this picture gives the impression that the overall cool. To reinforce this effect, the best way is to use a white board as the background, and then illuminated by a blue piece of cardboard aluminum foil. Of course, you can simply put a piece of blue as a background to use photo paper. Water and glass will increase the background color, and reflection will make this picture becomes angry. In order to state solidification of the movement of water down, choose 1 / 1000 ~ 1 / 2000 seconds exposure time is necessary, as shown below.

Use of reflection

Clouds reflected in a broad reflection in the water, the flat surface reflection of the sky color. The sky is almost perfect in the photos show up in the abstract, blue plane became the main theme. You go under the "golden section" rule for the photo composition. This means that the important image elements to the page on the ratio at 2:3. The middle of the upper horizon in the photo, such a match will lead to more harmonious picture, as shown below.
