Photography and Lighting

Photography requires a few skills to make your prints look professional. One part of making a print professional is lighting. Lighting in photography takes a little planning and understanding of a few techniques. You best subject or object might not turn out that way if the proper light does not help to laminate the area. Below are a few tips on using light for photography.

First you must decide if you will use artificial or sunlight. If you are using sunlight you will rely on the Kelvin scale to determine the temperature of light and therefore the color of light. The color of light is important to maintaining the colors you see around you. For instance the warmer the light the redder the light will be, thus you may need to pick the time you will go out and shoot photographs. Outdoor lighting offers so many different times to take pictures depending on your need.

Next a photographer needs to understand the sun's color scale. Pictures tend to lead the viewer towards certain feelings; often softer colors evoke more emotion. So understanding the suns impact on the colors will help you find the correct time of day. The sun evokes blue hues in the morning hours, while closer to noon you will find more neutral colors. The neutral colors can take away some of the definition you want in your print. Knowing how you want to shot the picture will also help you determine when you wish to take the shot.

When using natural light you will need to work with the angle and direction of the sunlight. If the sunlight is broad and diffused you will have softer shadows while the more narrow the light is focused the more shadow you can create. Often at noon when the sun is in mid arc you lose definition of the subject. The subject could look grainy. This is why shadow is used; the shadows can give you more quality to the print if used correctly. This adds to the beauty of your pictures.

You can also modify sunlight through certain techniques. Modifying sunlight when taking portraits outdoors requires the use of a background. You may wish for a breath taking landscape that will provide more composition to the photo. You may need to block the sun if it interferes with you or your subject's sight. You might also bring in a white surface to fill the shadows. Landscape photography requires less work than usually natural light for portraits. In fact using natural sunlight for landscape photography without modifications can yield you a better photograph.

Landscape photography uses nature to provide the light and shadows. This is why you need to understand the light scale and temperature. Time is the most important aspect of using sunlight. To understand natural lighting you need to understand the affects the sun will have at certain times of the day. For instance if you are in a thickly vegetative forest the sunlight will have difficulty streaming in unless it is over head. You will have natural shadows in the forest and remember you can move around your subject to find the best angle with the sun.

Photography is an art that requires techniques and practice. Lighting is a major part of photography, especially when you are using natural light. Sunlight can bring plenty of shadows or take them away depending on the time of day. Knowing the best time to take a photograph depends on the sun's angle. Photography is an interesting hobby and profession when practiced properly will give you plenty of prints for your home and others.

Whether you are a professional or a novice photographer, you want to produce some exquisite pictures with the proper lighting. With this in mind, choose your lighting according to your needs and the needs of your subject or object. Your pictures will be delightful with brightness when you use the best lighting situation.

Camera Phone Photography: Guides to Better Photos

The current camera phone is without doubt much better than the same camera phone at a few years ago. The built-in cameras on smartphones are now able to take decent photos. But for best results with the mobile cameras, few points should be considered. Here are most important tips to avoid unpleasant side effects on camera phone snapshots.

Under the right conditions, the results of the built-in camera phone can certainly compete with entry level compact cameras. If we considered the following points, your camera phone can make great snapshots.

Here are your guidances:

Camera Phone and Resolution

Most mobile phones come with high resolution camera. But hardly anyone knows what hides behind the term megapixel. As a general rule: the dimensions of a photograph in pixel multiplied together, gives the megapixel value. At a resolution of 2,048 x 1,536 pixels, this would be so 3,145,728 pixels, or in short: 3.1 megapixels. This means that it is possible for enlarging the images due to the large megapixel value. About the quality of the data, however, say nothing.

Nevertheless, just stating the megapixel values up to 10 is extremely important, because low-resolution details can be mapped correspondingly less. Therefore, it is nonetheless, the higher the better and yet at the same time respecting the storage capacity! High resolution photos take up more space. In addition, with most smartphones, the highest resolution is not even necessarily. Often set to "Normal" by default, whereas with the "fine", or "super fine", better results can be achieved.

Lighting on Camera Phone

Even current digital cameras have trouble with it, and for camera phone it is essential: the lighting. With the built-in flash, it is often not done, because often the LED flash will result in over-exposed results with tough shadows and extreme contrasts - and sometimes even color distortions. For optimal results, therefore, prevail in the scene accordingly optimal lighting conditions. Basically, the flash can be viewed only as a last resort, before the images are silhouettes, or completely disappear from the scene.

Zoom

Many users disappointed when looking at the results, despite ultra-high resolution coarse and grainy. This is not uncommon on the previous use of the built-in zoom. For what many do not know, camera phone doesn’t have a real zoom (optical zoom), but simply scaled up the photo shot. Pixels are to be interpreted by the software, which produces pixelated images. This is called a "digital zoom", and should be avoided. When the zoom is not an optical zoom, hands off!

Shake

Motion blur looks great - at least for the videos. In contrast, the blurry images are annoying. And here's the real advantage of phone cameras is also the root of all evil. Because in lightweight, small mobile phones, the device is unsafe in the hands and even the tiniest tremor is passed directly to the camera. Here, small adjustments will help. To avoid gross fluctuation, usually helps to lean on the pillars, walls or other objects. Tremor can be corrected by restraints of the elbow, either on objects or entangled at a pinch on the arm. Additional equipment such as tripods is mostly useless, since they charge the camera phone to the basic idea of mobility.

Canon 5D Mark III for 2011?

It is almost certain that Canon will bring the successor to the Canon 5D Mark II this year. While Canon has already offers more DSLR cameras this year, Canon 5D Mark III has its own charm.

During a workshop of the famous photographer Vincent Laforet, suggested that in 2011 may the successor of the Canon 5D MK II will be released: Canon 5D Mark III. This model will probably get a boost megapixel and equipped with an even more sensitive sensor. This statement supports other rumors, but it may take a while. Canon behavior manifests itself in this matter closed, so we do not expect a comment. Laforet, however, must reckon with a potentially severe reprimand, because he has talked. Although it is quite possible that he has just speculating like everyone else.

I wonder if the new Canon 5D Mark III will be equipped with a proud 3K resolution (3072 x 1728). That would make it interesting filmmakers who do not want to deal with effects and color corrections. Of course they will use but not 5D, when they make these thoughts.

How to filming with the Ricoh PX?

The Ricoh PX supports recording video clips. Note however that this need over classical image capturing significantly more space on the inserted memory card.

Regardless of the size of the inserted memory card, you can not per movie file over 4GB or 29 minutes to record movie. In some memory card types, it is possible that the video recording is automatically disabled before reaching this limit. How far the image can be zoomed depends on the selected video resolution: with HD video, you use a 2.8-fold, with VGA video, however a four-fold increase over the digital zoom the digital camera.

The video mode you get the standard or premium-shooting mode the digital camera on the small button above the right film at the back side (camera icon). In the course of the Ricoh PX sets the exposure and focus automatically detects and instantly starts recording the video so that they are particularly well suited for spontaneous clips.

How to create black and white images using software?

When a photographer wanted to take up 20 years ago, black and white images, he had even before the first shot to make a conscious decision. The next step, he then laid in place of a conventional color film Black and white film in the camera.

In this age of digital photography, the picture in the truest sense of the word has changed: In modern cameras, a small adjustment ranges in the menu for switching between color and black and white images. Also, color images can be transformed in the wake of the PC in black and white images without further notice. The latter variant is of course very convenient because you can change later on this way every color still photo. Conversely, you can make an image that was recorded from the outset about the black and white mode, the camera is no longer relevant, later in color.

First, check whether your digital camera has such a black and white mode. Very often this is to see the Motive of each device. Also, some camera manufacturers to offer creative filter, place the filter over a black and white color photographs. Regardless of the way, the result looks mostly the same. If your camera does not have such a mode that is said about the way computer-processing: Familiar tools such as transform "Adobe Photoshop" your photos in instant snapshots in SW.

The fastest way to convert color images is to convert the RGB images in the grayscale mode. This is the easiest way of getting inside the image editing to a black and white photos, but unfortunately he has no influence. Prefer to offer is more a function of the quality programs such as Adobe Photoshop. You can use the "Channel Mixer" specifically from the three color channels red, green and blue brightness of the mix proportions to be used for the construction of the grayscale image. In this way, can be achieved for example, both very hard and very soft contrasts implementations.

Finally, you can consider whether you want to leave it with the conversion to the monochrome screen. For example, the photo in question using the "Hue / Saturation" can be colored monochrome, while a sepia effect is slightly yellowed and accordingly look old. As an alternative to the fee-based Photoshop-like effects can be achieved through the free program Gimp or Bwork.

How to work with a light tent?

Especially in the professional product and object photography light tent is a standard feature of every photographer.

A beautiful clock, a car or a cell phone will eventually disappear behind neither endless reflections, even in a gray shade. This balancing act is a major challenge for the lighting: the lights are set too intense, possibly reflected the environment in parts of the object to be photographed. If you drive, the light intensity during its return, the object will turn quickly to dark and pale.

The solution: A light tent, the functioning of the name comes pretty close. The aim of such a light tent uniform scattering of light to suit the scene is around. In general, these are a transparent cone with an opening through which can be pushed through the photographer's digital camera. Scan the object is placed in the next step in the middle of the tent. Trappings positioned headlights finally deliver the luminous effect.

Of course, light tents are not available for all types of product photography: To illuminate a car in this way, it requires a professional studio setting. Smaller objects, however, you would like to set properly, for example, an Internet auction scene can be mapped in the home's basement or at your desk using the light tent effective without further notice.

Tip: It may not always be expensive. Professionals buy their light tent with a specialist supplier. Opportunity photographers on the other hand can also help with a form placed in bed sheets. Also Paus, parchment or greaseproof paper constructions are possible. For small objects such as clocks you need is a rolled-up 24-inch sheet of paper completely. The opening for the camera should always be large enough so that the autofocus-knife is not hindered in their work.s

Camera to Make Children Enjoy Photography

Digital cameras tend to be difficult for children to use. In addition, expensive camera shipments in children can be expensive.

Consumer Reports tested a digital camera specially designed for children and use the target demographic for your test. Fun-loving photographer accept thirty five camera designed specifically for children.

Consumer Reports models include Fisher-Price, Crayola and Lego, and testers also gave the children to compare a regular camera. Cameras proof from $ 35 to $ 60.

Adults tested battery testers, which turned out pretty good in all cameras. Shutter lag is also calculated, or how long to wait between pictures. Most models of short shutter delay. Elderly testers also assess the quality of the picture.

Most testers thought that the digital camera is easy to use, but each has slightly different characteristics. Like most common digital camera, child friendly model can be connected to a computer that can edit images, print or share.

Children can add up to $ 50 Disney graphical models and even built a Lego model for $ 60. Quality, $ 40 V-Tech Kidizoom Camera is the first choice. He also has a built-in graphics to be added to images and games.

Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II Review

Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II announced in July 2009, the second version of the fast stable telezoom professional company. It is the successor to the AF-S Nikkor 70-200mm 1:2.8 G ED VR, which first appeared in 2003 and brings to the table fully remastered mesh designed to meet the demands of the latest high-resolution format FX D3x, accompanied with a vibration reduction system to improve Nikon acquisition offer up to four stops of stabilization.

Optics, as expected for this type of lens, quite exotic, with 21 elements in 16 groups. No fewer than seven of them are formed from extra-low dispersion (ED) to minimize distortion, and the last Nikon Nano Crystal coating is used to combat the outbreak. One of the best management focus mode is the addition of new A / M, to prevent accidental movement of the main focus as the autofocus is also operating. Building a quality suitable for professional purpose workhorse, with a barrel made of magnesium alloy, as well as professional level Nikon DSLR bodies, and extensive sealing against dust and moisture.

Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II: What's new

Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II has high hopes for life, like its predecessor, is considered a pretty good body-DX format best in its class. But with the change of the sensor full-frame 'FX', deficiencies in the area of ​​the focal length of the picture is quite open, with soft angles are not uncommon, even in small openings and open the heavy bullets loose. Therefore loyal Nikon (and most important base of professional users) expect that this new model can solve this problem in full screen format without compromising the performance of the sensor is significantly smaller. We can see if Nikon has achieved this goal.

As for the controls and layout, the new version loses the three AF-stop buttons arranged around the front of the barrel, replaced with inlaid rubber grip. Distance scale of the focus has moved too far from the front end to more visible gap between the zoom and focus ring. Control switches on the left side of the barrel slightly modified function - now the focus limiter switch to limit the range of approximately 5 million instead of 2.5 m, which should reduce poaching a small fraction of the benefits of sports photographers. There is also a third position focus mode switch is called A / M, which is different from the M / A mode (still available) to give priority autofocus to manual focus, so that every movement of the ring during AF operation Focusing taken into account, not canceled.

Nikon has updated the stabilization unit in accordance with the specification Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II and said it now offers additional benefits stop (4 stops vs. 3). As usual there are two modes, "normal" automatically see in the picture (and then turn off the stabilization to the required direction), and "assets" that always gives stabilization in two dimensions.

A final distinction in the specification is the maximum increase, unfortunately, not widely available when the lens was first launched, and since then has caused some controversy. Because while the minimum focusing distance is reduced slightly to 1.4 million, an increase has slowed further, from al 0.12x 0.16x. This means that while previous models could, in principle, capture the image area as small as 9 x 6 inches (22.5 x 15 cm) FX camera, the best of the new version can do is 12 x 8 inches (30 x 20 cm). This shows that the angle of view is significantly magnified in close focus.

The long-awaited successor to the Nikon VR 70-200mm F2.8 always to close examination when he finally saw the light of day. For while the original is a remarkable lens on a DX camera, which suffers from several well-known optical defects in the frame of the camera that became all-too-clear about the release of D3. And the good news is that the AF-S Nikkor 70-200mm VR II F2.8G complaints as well and truly put to bed - missing corner opaque, darker towards the end of the term, replaced by the 200 mm can be truly described as a very good.

In fact, almost any measure, the newcomers or better than its predecessor, or at least as good. There are a large number of optics including DX, but in our opinion the new version is sharper and the width 200 mm, in exchange for a slightly softer at F2.8 in the middle of the range. FX is the most obvious differences, and improvements in the telephoto end, especially, of course. A sharper angle, the bullet is reduced, although significantly less distortion, the penalty is only increased by almost tangible in chromatic aberration. The picture quality on the distance of closest approach is much better too. Rarely We are very impressed with the performance of optical zoom as we have a new Nikon.

It's not just the optics of the well, however. Construction and management of virtually flawless, and the balance of the camera lens has been improved - you do not have a sense of the initial evaluation. Autofocus fast, quiet and precise and the image stabilization is quite good as it gets. We found the revised Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II a good system for stabilizing a solid 3-4 to stop holding hands and we are pleased to see one of our objections to the previous version (some over-enthusiastic lens switch to widescreen mode when it should not) seems to remain . This usually means that the lens just give it a shot with minimal fuss, and after hours - exactly what you need from the hard-working professionals.

Naturally, however, not everything is perfect, and there are some catches. The most obvious is the viewing angle increases Center (also known as breath focus), which means that although the prospect of a bit of a new lens, the highest increase is smaller. This has implications for users who often shoot at a distance of 200 mm and relatively close, you may need to consider carefully whether this behavior can ultimatum (unable to reproduce the near future can be better tight lens). But we can not help thinking that for most shooters, just not a problem, in fact, in many cases more than offset by dramatically improving image quality at close range.

In practice, we found a ribbed rubber grip to the front of the lens, which adorn the space previously occupied by the AF-STOP, a little annoying, it's easy to get confused with the focus ring to try to find touch. It's not a big deal (and not only intended to cover it with tape), but it was not necessary. Perhaps most importantly, includes living quarters three AF ​​stop buttons at the top - if you use frequently, then the losses will be significant.

The only downside is in the design of the lens cover. First, it is too shallow, so it is more effective than it should be in the shadow of the lens just like the slightly off-axis light that can cause serious problems to light. There seems no good reason, because the hood does not come close to the sketch on FX. Second, the profile slightly curved "petals" front means it is wise to try to support the lens hood, while not in use, fell from the potentially very expensive (although it can only be a concern for the small minority of users, such as concerts or event triggers that work in confined spaces ). But we can encourage Nikon to evaluate the design and production of campaigns to improve - the lens will be installed for you.

Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II: Conclusion

In general, however, it is impossible to conclude anything other than the Nikon AF-S Nikkor 70-200mm 1:2.8G ED VR II is one of the most important of its kind and the perfect companion for high-end Nikon bodies D3S and D3x. DX shooters may have many reasons to update the previous model, but for obvious improvement FX users. How long title is doubtful, with Canon and Sigma also just released a new image stabilized 70-200mm F2.8 lens, but now only as good as it gets.

How to select the recording mode on Casio EX-TR100 TRYX?

The Casio Exilim EX-TR100 TRYX digital camera has various recording modes, you can select via the touch panel on the rear panel.

To do this, follow these steps:

1. Turn on the Casio Exilim EX-TR100 TRYX digital camera.
2. Jump to the shooting mode, where playback is active. Then touch the shooting mode icon. If it does not appear, scroll through the menu tab.
3. Now touch the icon of one of the following recording modes:

• Automatic: This is the pre-activated recording mode, the Casio Exilim EX-TR100 TRYX. All settings (focus, etc.) are done at the moment of recording automatically. This mode is suitable for most types of everyday consumption.
• BEST SHOT: The BEST SHOT mode, you select from a range of scene modes. Thus, the image output parameters are adapted to a specific shooting situation (for example, "night", "Portrait").
• Premium car: In the Premium Auto mode detects the Casio Exilim EX-TR100 TRYX own, whether you are taking a landscape or a person. Depends then several adjustments are made automatically. The image quality is therefore usually higher than the automatic mode.
• HDR Art: Transform into this creative mode your recordings to digital art. "HDR" stand for "High Dynamic Range" and gives the photos a higher expression of a wider dynamic range.
• Camera pan, if you want to capture a large landscape, you can use the Casio Exilim EX-TR100 TRYX pan in this mode along the horizons. In the course of several single shots are made which are then combined into a large L-recording.
• Motion Shutter: This is the classic self-timer. Once you press the shutter button in this mode, a countdown begins. Only at the end triggers the Casio Exilim EX-TR100 TRYX.

Bridge Cameras

The bridge that the increase in digital cameras are ergonomic and physically resemble DSLRs and share with them some advanced features, but share with compacts with a fixed lens and a small sensor. Such as agreements, live preview of most use to frame the picture. Using the same contrast detect autofocus mechanism, but a lot of bridge cameras have manual focus mode, in some cases with a separate focus ring for greater control. Originally they were "saving" the gap between point and shoot camera affordable digital SLR that did not previously exist.

Given the combination of large physical size, but with small sensors, many of these cameras have a lens that is very, very determined with a wide focal range and quick release, partly to compensate for the inability to change lenses. Some qualify as a superzoom lens. To compensate for the decreased sensitivity of small sensors and the digital camera almost always include an image stabilization system to allow an exhibition of hand.

The cameras are sometimes marketed as and confused with digital SLR cameras since the appearance is similar. Bridge out the lack of reflex digital SLR system, usually have a fixed (not interchangeable) lenses (although some have wires in order to connect the accessory wide angle or telephoto converters), and can usually take movies with sound. The landscape is formed by looking at either an LCD or electronic viewfinder (EVF). Most have a shutter lag of a real digital SLR, but are capable of good image quality (with sufficient light) while the more compact and lighter than DSLRs. High-end models of this type of resolution in the bass and midrange DSLR comparable. Many cameras can store images in image format, raw or processed and compressed JPEG, or both. Most have a built-in flash similar to those found in a DSLR.

On sunny days, the quality difference between a good compact camera and a digital SLR, but a bit more portable bridgecams, cost less and have the ability to zoom DSLR. Bridge cameras that can fit well with the task of each, except in the pursuit of professional-quality photos.

In low light conditions and / or equivalent ISO above 800, most of the bridge cameras (or megazooms) lack of image quality even compared to the DSLR entry level. However, they have a great advantage, often not appreciated: - a greater depth of field because small compared to the digital SLR sensor, allowing a large hole in the shortest exposure time.

A 3D shooting mode was introduced in 2011, when the camera takes a second picture from a slightly different perspective, and provide a standard. MPO files for stereo display.

Digital SLR Camera

DSLRs often preferred by professional photographers, as they still allow an accurate preview frame near the time of exposure, and because DSLRs allows users to choose from a variety of interchangeable lenses. X0y0zs most also have a feature that allows accurate depth of field preview.

DSLR operational principle is as follows: for the purpose of viewing, the mirror reflects the light from the top of the lens placed at an angle of 90 degrees. After three times you will find through the roof pentaprism, repairing the eye of the photographer. During the exposure, the changes in a mirror set up, reducing the opening (if you stop down, or a smaller set than the width of the opening) and the shutter opens, allowing the lens to project light image sensor. One second after the shutter covers the sensor, stop the exposure and lower the mirror while the shutter. During which the mirror turns the so-called "blackout viewer." A mirror of fast action and the shutter would prefer not to delay action picture.

All this happens automatically at the time of milliseconds, with a digital camera designed to make it 10.3 times per second.

Many professionals prefer DSLRs also for a sensor larger than a compact digital thermometer. DSLRs has a sensor that is usually much closer in size to the traditional film format that professionals are now beginning to use. These sensors allow for greater depth of field and angle of the same image for the movie format, as well as the relatively high signal noise ratio.

The DSLR The term generally refers to a bedroom that resembles a 35 mm camera format, although some medium format cameras are technically DSLRs.

A camera that is based on the principle of single-lens reflex (SLR), using a mirror to show the images in the viewfinder to capture. Cross section (side view) of the optical components of SLR shows how the light passes through the lens (1), which is reflected in the mirrors mirror pentaprism (which should be at a right angle 45 degree) (2 ) and is expected to matte focusing screen (5). By condensing lens (6) and internal reflection in the roof pentaprism (7) the image is projected through the lens of the eye (8) for eye photographer. The focus is either automatic, activated by pressing the shutter button or a special AF, and especially in the case of a film SLR autofocus or manual, where the photographer to manually focus the lens by rotating the ring on the lens barrel lens. Once the image is a picture, the mirror up changes in the direction of the arrow, the focal plane shutter (3) open, and the image is projected and captured on the sensor (4), after the action closed the shutter the mirror back to the 45-degree angle, diaphragm reopening, and built-in drive mechanism re-tension the shutter for the next exhibition. Often there is a ring of soft material around the focusing screen, which helps reduce the impact of the slap of the mirror and help seal the mirror box of light entering the eye [1]. Some high-end digital camera features a shutter in order to further reduce the light that you can go there during long exposures.

SLR Cameras

Before the development of SLR, all cameras with viewfinders are two optical light paths: one path through the lens to film, and other road is placed on top (TLR or twin-lens reflex) or edge (Scout). Since the viewfinder and the lens can not share the movie with the same optical path, this lens is aimed to see the movie to converge on the lens at a fixed point in an area in front of the camera. This is no problem for the pictures taken at medium range or more, but causes parallax error-frame close-ups. In addition, the focus lens reflex camera quickly when a wider hole (as in low light or when using low-speed film) is not easy.

The single-lens reflex (SLR) camera is a camera that usually use a semi-automatic moving mirror (hence the name "shadow", the reflection mirror) that allows the photographer to see what is captured by film or digital imaging system, as opposed to pre-SLR cameras where the view through the viewfinder could be significantly different than what was captured on film.

Most SLR cameras allow upright and right lateral view by using the roof pentaprism situated in the optical path between the reflex mirror and viewfinder. Light, which comes either horizontally or vertically inverted after passing through a lens, is reflected upward by mirror reflex, the pentaprism which reflected many times to improve the inversion caused by the lens, and align the image in the viewfinder. When the shutter is released, the mirror moves out of the way of light, and light shines directly onto film (or in case of a DSLR, CCD or CMOS imaging sensor). Canon Camera Pellix is ​​exceptional for a moving mirror system, which mirror is a thin skin beamsplitting well.

Focus can be adjusted manually by the photographer or automatically by the autofocus system. The viewfinder may include matte focusing screen that is located just above the mirror systems to spread the light. It enables accurate estimation, developing and focusing, especially useful with interchangeable lenses.

Until the 1990s, the SLR is the most advanced system available to preview pictures, but the development and refinement of digital imaging technology and a screen-camera live preview LCD is overshadowed by popularity of SLR. Almost all compact digital cameras are cheap now includes an LCD screen that lets photographers preview to see what CCD is captured. However, SLR is still popular in high-end cameras and professional because they have a camera system with interchangeable parts, allowing customization. They also have a shutter lag is less, allowing images to be more timely. Also pixel resolution, contrast ratio, refresh rate, and color gamut LCD preview screen can not compete with light and shadow detail SLR viewfinder optics directly viewed.

Optical dan Digital Image Stabilization

Photography, image stabilization usually allows use of shutter speeds slower than 4.2 points (exposures 4-16 times), although the effective rate reported even slower.

General rules for determining the slowest possible shutter speed for hand without any visible confusion due to the vibration of the digital camera does the same as the equivalent of a 35mm lens focal length. For example, the focal length of 125 mm on a 35mm camera, vibration or movement of the camera affects the sharpness, if the speed is slower than 1 / 125 second shutter. As a result of slow shutter speeds 3-4 stops allowed by the SE, the captured image at a speed of 1 / 125 seconds in a conventional lens can be taken in 1 / 15 1 / sec with IS-equipped lens 8 and almost the same quality. Sharpness is obtained at a certain speed can increase dramatically. [1] In calculating the effective focal length, it is important to account for digital cameras by the user. For example, many digital SLR cameras with image sensors of 3.2, 5.8 or 1 / 2 frame size of 35mm film. This means that the frame of 35 mm was 1.5, 1.6 or 2 times the size of a digital sensor. These values ​​are defined as the factor of the last harvest, the crop factor of field of view, focal length multiplier, or for reasons of format. Growth chamber with a factor of 2x, for example, a 50mm lens works in the same field of view as a 100mm lens used on a 35mm film camera, and usually can be handheld at 1 / 100 per second.

However, the image stabilization does not prevent motion blur caused by subject movement or camera shake. Image stabilization primarily designed for and is able to reduce blur resulting from normal minutes, shaking the lens due to hand shot. Some of the lens body and the camera or the "way" the second panorama mode is more aggressive, both described in more detail later in the optical image stabilization.

The image stabilization, features can also be useful for photography with the camera is technically effective, but not fixed in place. Pentax K-5 and Cr can use sensor shift its ability to reduce exposure Star trails in a timely manner when an accessory is equipped with GPS position data. Consequently, stabilization compensates for the motion of the Earth, not the camera.

There are two types of deployments - based stabilization in the lens or body-based. See where the system is stabilizing. Both have advantages and disadvantages.

Image stabilization (IS) is a family of techniques used to reduce the blur associated with camera movement during exposure. In particular, the offset and tilt (angular motion equivalent to yaw and pitch) of a camera or imaging device. It is used in image-stabilized binoculars, still and video cameras, and astronomical telescopes. Camera, camera shake, especially problems in the slow shutter speed or focal length (telephoto) lens. The use of video cameras, camera shake causes visible frame by frame instability in the recorded video. Astronomy, the problem of lens-rock added by variations in the air from time to time, causing the apparent position of the object changes.

Optical Image Stabilization

A comparison of close-up photographs of the keyboard and optical image stabilization.

A optical image stabilizer, often abbreviated as OIS, IS, or the operating system is a mechanism used in the camera or camcorder that stabilizes the recorded image by varying the optical path of sensor. This technology has been applied to the lens itself or by moving the sensor as the last element in the optical path. The basic elements of the optical image stabilization system is to stabilize the projected image on the sensor before the sensor converts the image into digital information.

Digital image stabilization

Real-time digital image stabilization is used in some video cameras. This technique shifts the electronic image of the video frame by frame, enough to resist movement. Using the pixels outside the boundaries of the framework aims to provide a buffer for the movement. This method reduces the annoying vibration or improve video image quality by allowing a person to increase exposure times without blurring the image. This method does not affect the level of image noise, except in the extreme limit, when the extrapolation of the image.

Unfortunately, there are still many camera companies market their cameras' digital image stabilization, "when in fact it has a way of sub-optimal exposure time of the image, producing images with less blur, but more noise.

The main disadvantage of this solution is that the lack of definition of rock in the middle of low-light conditions is impossible to correct through post-processing system, image stabilization, so in real life works only for a short exposure time (day).
