Digital cameras that use reusable memory cards instead of the movie will be much more creative control of film cameras can. With a digital camera you can transfer recordings to the computer to crop, to adjust color and contrast, and add textures and other special effects. The final paper or T-shirt, or e-mail, all of which come with the software, usually with the camera. You can make prints on an inkjet color ink, or the school from the memory card into one of a growing number of laboratories. You can split the file to upload a photo sharing website for storage, exhibition, and others.
Such as camcorders, digital cameras have LCD viewers. Some cameras can take pictures, but the resolution of a typical camcorder is not playing for a good camera.
What is available
The leading brands, Canon, Fujifilm, HP, Kodak, Olympus and Sony, other brands are consumer electronics, computer and traditional camera and film companies.
Digital cameras are classified as many pixels, or dots, contains the image sensor. One megapixel equals 1 million pixels. A 3-megapixel camera can be excellent 8×10s and pleasing 11×14s. There are also 4 – to 8-megapixel models, including point-and-shoot for those who are making larger prints or for maintaining sharpness if you want to use only part of the original image, are suitable. Professional digital cameras up to 14 megapixels.
Rates: $ 200 to $ 400 for a 3-megapixel, $ 250 to $ 400 for 4 pm to 5 megapixels, $ 300 to $ 1,000 for 6 to 8 megapixels.
MAIN FEATURES
Most digital cameras are highly automated, with features such as automatic exposure control (shutter speed, aperture, or both to succeed in this light) and autofocus.
Instead of film, digital cameras usually record their shots on flash memory cards. Compact Flash and Secure Digital (SD) are the most common. Once quite expensive to have such maps in the price – a 128 megabyte card can cost less than $ 50 fell. Other types of memory cards used by cameras, Memory Stick, SmartMedia and xD-Picture Card A pair of cameras, including some Sony models use, 1/4-inch-R CD 3 or CD-RW.
To save images, transfer them to a computer, usually by connecting the camera to the USB or FireWire port or insert the memory card into a special reader. Some printers can print the cards and place, without having to establish that the images on a computer. Image management software, like Adobe Photoshop Elements, Jasc Paint Shop, Microsoft Picture It, and ACDSee you can tweak the size, crop, and digital images with a computer. Most digital cameras work with Windows and Macintosh computers.
The file format is used for JPEG images is a compressed format. Some cameras can save images in uncompressed TIFF format, but this setting has enormous files. Other high-end cameras have a RAW file format, which provides the image data without processing by the camera.
Digital cameras typically have an optical viewfinder and a small color LCD viewer. LCD display is very accurate in determining the real image is obtained – is better than most optical viewfinders – but the use of drums and more difficult to see under the scorching sun. You can also use the photos that you have already taken the LCD. Many digital cameras provide a video output, so you can view pictures on a TV screen.
Some cameras can record an audio clip with a picture. But these clips with additional storage space. Some can accept only video you want, but the frame rate is slow and the resolution poor.
A zoom lens offers flexibility in setting off strikes and closes the distance between you and your subject – ideal for those who want to move too quickly reversed. Typical 3x zoom on cameras ranging from a traditional 35 millimeters moderate wide-angle view () to moderate telephoto (105mm). You can also cameras with advanced search is between 8x and 12x zoom, giving added versatility for outdoor photography. Other new cameras go up to 24 or 28 mm wide-angle end, making it easier to take in a scene in the immediate vicinity, such as a crowded party.
Optical zoom is superior to digital zoom, the center of the image, without actually increasing picture detail, rising to a vision a little 'crude.
The sensors of digital cameras are typically about what light sensitive as ISO 100 film, even if some of you may increase this setting. (At ISO 100, you'll probably be forced, a Flash at home and in low sunlight.) A camera's flash range tells you how far is the flash from the camera the proper exposure before: If the subject is out of reach , you 'll know to bridge the gap. Digital cameras are some underexposure before the image suffers greatly tolerate.
Red-eye reduction light of a light on this issue directly before the main flash. (A camera whose flash unit is farther from the lens reduces the risk of red eyes. Computer image processing can also fix red eye.) With automatic flash mode, the flash of the camera when the camera registers light inadequate. Some new cameras have built-in ability to correct red-eye.
Some cameras are powerful telephoto lenses are equipped with image stabilizer. This can compensate for camera shake, have a slower shutter speed than otherwise would be in favor of the motion. But an image stabilizer does not compensate for the movement of the subject.
Most of them come new 6 – to 8-megapixel camera with full manual control, including independent controls for shutter speed and aperture. The serious shutterbugs control over depth of field there, shooting action or shooting scene with the darkest areas of the image.
HOW TO CHOOSE
The first step is to determine how to use the camera most of the time. Consider these two questions:
How much flexibility to enlarge the images you need? If in particular the 4×6 snapshots, they want to make a camera with a 3 – or 4-megapixel resolution is good. This camera is also a 8×10 print of an entire image, without change, so strong, as shown by a 6 – or 8-megapixel model. But the photo to enlarge the image or enlarge more than one part of it, you'll want a 6 – to 8 megapixels.
How much control you want over exposure and composition? Cameras for the average auto point-and-shoot photos with a 3x zoom lens, snap shooters and amateur intended to dedicate the time anymore. Fully functioning cameras in the 6 – to 8-megapixel range offer the features that they want to get more-dedicated photographer. Two of the most important skills are a range of 5x to 10x zoom or more, with which you bring distant outdoor subjects close and you can 'shoot candid portraits even without being directly in the face of the subject, and a full manual control They determine, add to the shutter speed and aperture. "
Once you have the priority of performance that you need to have created a camera, you can further narrow the selection, in the light of these factors Comfort:
Size and weight. The smallest, lightest models are not necessarily economic 3-megapixel camera. And the bigger and heavier is not necessarily located at the upper end. If possible, try to cameras in the store before buying. This way you will know what suits your hands, and will be stopped safely. In our tests, we found that some of the smaller leaves much space, even for small fingers.
Battery type and life. All digital cameras can be run in two ways, with rechargeable batteries, a expensive battery pack or a set of AA batteries. In our tests, the cameras, he had neither the type of battery, a clear performance advantage. The cameras offer better results up to 300 shots on one charge, while the worst manage only about 50 We find it more convenient, a camera that accepts AA batteries of its own. You can buy economically, rechargeable batteries (plus charger) and drop into a series of lithium batteries or disposable alkaline rechargeable when running down the middle of recording the day.
Cameras. With point-and-shoot cameras like the one we tested, it will be necessary after each shot, as the camera processes the image of waiting. Most models let you take a picture every few seconds, but few do wait 5 seconds or more. You get frustrated when you take pictures in a row.
Your other cameras. If you have a camera to add to your lineup, or trade for up to a versatile model, first, that a camera is compatible with others. If so, you can share your memory cards and batteries. Models within a brand line of cameras are often similar. So that is the brand that you remain lowers the learning curve for the new camera for family members to switch between cameras.
