A digital camera, against a movie or a video camera, uses an electronic sensor to transform images (or video) into electronic data. Modern digital cameras are typically multifunctional and the same device can take pictures, record videos, and / or 2005 Ton.Im digital cameras at the starting point for pushing traditional cameras in many markets. shrinking device sizes have recently allowed miniaturized digital cameras into multi-functional devices such as mobile phones and PDAs including werden.EinstufungDigitalkameras can be divided into several groups: * professional video cameras, video cameras, as used in television and film production. These sensors typically have multiple images (one per color to improve) the resolution and color space. Professional video cameras usually do not have a VCR or microphone. * Camcorders used by amateurs. It is a combination of camera and video recorder to create an all-in-one production unit. They usually contain a microphone to record sound, and feature a small LCD screen to the video during shooting and playback sehen.Still camera digital cameras are generally identified by the use of flash memory and USB or Fire Wire for more storage and transfer gekennzeichnet.Die have a rear LCD to review the records. They are classified in the mega-pixels, which is the product of their maximum resolution dimensions. The actual transfer to a host computer are often durchgeführt. All using the storage class USB mass (so that the camera appears as a disk) or on the picture transfer protocol and its derivatives with a CCD (Charged Coupled Device) is for a chip, which included a grid of phototransistors to light intensities in the focal plane of the lens Sinn.Es a recent application of a second type of chip called CMOS (Complementary Metal-Oxide Semiconductor) sensor , and this chip is often distinguished by a good CCD it uses less energy and other types of materials sensitive to light, but the differences are highly technical and many manufacturers are still coupled to the CMOS chip a charged device . For our purposes, a chip of a CCD. * Standard Digital Cameras: This encompasses most digital cameras. They are characterized by ease of use and easy focusing; This design allows for limited motion picture capability. They have a range to shoot. So, objects at multiple depths in the same household, accounts for focusing too lightly. It is also part of the reason professional photographers find their images flat or artificial-looking. They excel in landscape photography and casual use. * Digital SLR usually have a sensor nine times larger than that of a standard digital camera, and professional photographers and amateurs. They resemble ordinary professional cameras in most ways to give interchangeable lenses and Flash components that the user with maximum control over light, focus and Schärfentiefe.Sie are also larger and more expensive than their counterparts occasional-use oriented. They are excellent for portraits and artistic photography because they are adapted for different applications with a comprehensive range of modular interchangeable lens digital kann.

The first real digital camera, images from a computer file is probably the Fuji DS-1P of 1988, leading to a 16 MB internal memory that uses a battery to retain data stored in memory.

Digital cameras may also work, and not in the movie cameras, as they found: – Displaying an image on the camera screen immediately after taking it. – The ability to take thousands of images on a single small memory. – Include the possibility of video with sound. – The ability to delete photos and images allows the reuse of the storage they occupied edit. A digital camera is a camera, video or photos, or both, are performed digitally by recording images on a sensor sensitive to light. Most digital cameras to measure the distance from the subject automatically using acoustic or electronic techniques, but it is not customary to say that they have a rangefinder.

Because of dramatic changes in technology, digital cameras are very close and helping those people who hold the most precious moments and precious life. . to photography a few years ago people used a regular camera.

What is different is how the colors and the light reflected by the image pixel capture compared to chemical systems. You can focus a wide range of possibilities. Most digital cameras have two different types of image magnification, the magnification (zoom) which can be 35-150 mm equivalent lens, and a digital zoom which can be up to ten times (such as x10). This gives you opportunity with optical zoom, which can be limited in its depth of field monitoring and is subject to blur and the movement if the conditions are not only the right, and a digital zoom of the image pixel. If expanded to capture images at a distance is important to you, you need more megapixels and a lens system that gives you some control over its direction and management of initiation.

Today, people spend cameras, digital models. The obvious reasons, lightness, are framed by objects and pictures are recorded, stored and displayed. To make matters can be downloaded from the comforts of home and print images. However, if you buy one for the first time, chances are they have lost literally present the features and functions through the many brands out there on the market. They range from mega-pixels or through the manufacturer or by price range, or …. Well, there are many other possible classifications. The following guide is prepared with the intention to assist you in a practical model of your choice. Various FeaturesWeight This factor, much depends on the use of a digital camera. They want you to carry in your pocket or your bag, go for the lighter. Without doubt, they are comfortable, but they have tiny buttons, controls and scales, which can make handling a bit difficult. The older, heavier and have more features. Resolution The cameras are arranged as a mega-pixel resolution. It restricts the range of cameras and can help you with basic, intermediate and advanced groups. The range is 0 to 18 1 mega pixels mega pixels and a little more. The key to choosing the right pixel camera depends on how far you want to reach the goal. 2 megapixels and you get a little less strong images, and enough detail for prints 8×10 and smaller. The drawings are not very good, but decent enough to publish on e-mails and Web sites. These cameras are inexpensive. Because 6.2 million pixels ensures the increase in this area, the image quality is better than one. You get sharp images at all prices will rise. For example, Canon PowerShot S3, Fuji FinePix V10 etc. http://www. reviewgist. com / digital camera reviews? Resolution = 0. 1-to-5. 16 mega pixels or more, more is not always good. Remember, more megapixels means that the size of larger, expensive memory cards, and take more space on the hard drive of your computer. Example. Canon PowerShot Pro1 Canon PowerShot S80, etc. http://www. reviewgist. com / digital camera reviews? Resolution = 6 37-to-8. 32ZoomOptical zoom image of the objective lens is 3x, 4x, 10x and enlarged but keep in mind that are very sensitive to long-zoom camera shake. Used to cover a tripod to solve this problem. A 3x optical zoom means that they can appear three times a subject so close. A zoom lens provides optimum image quality. You can not too close to the object, but a photo editing software can help you crop your image. It gives better results than using the digital zoom. Digital zoom is an optical zoom of simulation, it only adds to the central part of the image. The objective in this case is not used. The effect of digital zoom is provided by the software inside. The result is usually a blurred image and digitized. You can zoom in cameras, the two effects that they provide both functions. Lens A dirty lens can ruin everything in a higher resolution and controls image processing. So before buying a judge the final image on a computer based on these criteria: Check the lens of the overall direction and focus, if the corners are as sharp as in the middle Check for flaring, ie, the circles of color and reflections when shooting towards the light source verify that the offer lens attachments, you can add wide-angle or telephoto attachments, to extend the zoom range whether manual and electronic zoom control, manual zoom offers more speed and flexibilityMemory Unlike cameras, digital cameras record images in memory. So, whenever the memory is full, you can download it and the device is ready to shoot again. The memory is of two main types: Installation and removable. Most low-end devices have onboard memory. removable memory cards have the advantage of the evolution of memory, particularly useful if you have many images in one trip. Flash Types It all started with photographers turn a tray filled with gunpowder, to illuminate the scene. Today, digital cameras with built-in flash automatically associated with a sophisticated light metering and exposure controls come.

Over the guide number, the more useful range of Flash. changes in the evolution of the speed sensor and / or the focal length of the lens, the guide number. Thus, producers are instead of the maximum flash range with the hypothesis that is fully loaded and the opening is wide open flash. Some common modes: Auto mode is known! Cameras with autofocus mode first fire broke out briefly on the issue of the Iris, then close the main flash, and finally the picture is taken. Fill-in flash modes to fill the shadows. Flash off mode to be in natural light. Night mode allows the foreground subject, without sub-background exposure. For maximum flexibility of Flash, you select a camera with an external flash shoe. Some models come only with external flash. Some varieties have both external and built-in flash units. Some models Compact digital camera with flash units are derived. Focus Type Most digital cameras have a focus on the combination of different transport modes. In automatic mode, when you press the shutter down, the focus is locked.

Different combinations of the main types are: Autofocus and manual focus autofocus and fixed focus Auto, manual and type of fixed camera focus standard models and cameras point shoot, aim and shoot with basic functions for those with advanced features and options and excellent macro capabilities. The flexibility with which these devices can be used in situations where it is difficult to frame the subject or shooting at the waist makes these models very popular. It is a quiet performer ideal for shooting in places where a closure valve box is not appropriate.
