Guide to Buy Digital Camera

Introduction



Digital Camera

Digital photography still trying to defend better. Higher resolution, more sophisticated controls and better technology, making all retrieval images is easier than ever before.

We'll explain the digital camera you need to know everything, ranging from large images with high resolution for storage and from exposure control to the color balance settings.

Large Picture

Megapixels still a problem for digital camera buyers, in part because manufacturers and sellers favor each specification. If you can not wait to consider in buying camera, you may be interested to make a decision based solely on megapixel count; that is why nearly all manufacturers display the number on the camera. But the camera needs more than just a high pixel rate to take great pictures, so consider other aspects. For example, a camera that takes too much time in between taking pictures, so many good scenes missing, and a great camera, the weight can be spent where the bag. Camera without manual controls can be amazing in the mood to take pictures in bright sunlight, but bad in more challenging situations.

Key features
Resolution: If you intend to take pictures only to send the e-mails to friends far away or to print images with a small size, most of the camera with any resolution will be biased to use. However, many more pixels gives greater flexibility - you can print sharper pictures at larger sizes, or cut small pieces and then print. Currently most of the cameras offer a resolution of at least 5 megapixels, which is sharp enough to print size 11-times-14.

Size, weight and design: To some users, how much weight the camera and if appropriate included in the pocket, perhaps more important than the resolution factor. We have been testing for a camera that weighs 2.3 pounds and only 4.2 ounces. Small camera feels comfortable, but often has several small buttons, to change the settings.

Zoom lens: The camera is cheap, often less good for a zoom lens. If we must choose between a camera with optical zoom and a higher resolution, we will choose a more sophisticated model with a zoom lens, meaning you do not need to enlarge the subject and then use software to crop the image. A few cameras now offer zoom ratings up to 15x. This lens is great for landscapes or sports photography, but you may need a steady grip or tripod to avoid blurry images due to the portrait of long-distance, if the camera has no image stabilization. You have to try an autofocus camera at full zoom: We've tested some models that are slow in focusing in full extension with low light.

Be careful of advertised zoom ratings. Many vendors combine the optical zoom (which moves the lens to enlarge the subject) with digital zoom captures only a little pixel and zoom images. Optical zoom gives you all the benefits of a maximum resolution camera, combined with the ability to get a closer target.

Manual focus: To make the close-ups or situations in which the camera could not lock the focus, switch to manual focusing can help you get the picture. Often ignore the simple camera manual focus or focus only rise, which forces you to choose a certain distance.

Storage: At the highest resolution, generally 5-megapixel camera can store six to eight images on the 16MB memory card. The size of the camera memory card that is not important, because you almost always have to buy one again (unless you are willing to transfer your images after every shooting). CompactFlash, SD (Secure Digital) Card and SmartMedia cards cost about $ 6 to $ 15 for 512MB, or $ 25 to $ 40 for 2GB.
