Choosing a digital camera and other equipment as is done by examining its technical characteristics. You may also want to hear reviews of current owners of cameras, as well as to compare the images made by different cameras at the same time in the same place. But at this point will be discussed is about the technical characteristics, as they determine how much the camera will be able to give you a colorful picture. You probably ever heard that expression, "And how many megapixels your camera?". This often hear when it comes to mobile phones with built-in camera. This trouble will not pass and a digital camera.
The view that more of them, the better the image quality, several erroneous and misleading many. This characteristic is responsible for a maximum resolution of the photo you can make a camera without losing quality. Quality is important to consider and matrix size, which are those same pixels. Therefore, an amateur camera may have more megapixels than professional. Picture quality depends on the matrix – a device with a certain number of photosensitive elements (pixels). It is responsible for color, noise, transmission of small details, depth of field.
The number of pixels does not always correspond to those in the product image, so an interest, according to a characteristic name given to the camera. A serious approach should be the choice of optics. First look at this option, as the increase (zoom): it can be digital or optical. Good cameras have and that, and another, and given only cheap digital zoom (digital zoom). Digital zoom is accomplished by increasing the frame after the shooting and cutting to the desired size, thereby losing quality. Optical zoom (optical zoom) is implemented using the zoom lens. Often the power supply digital camera, attention is drawn last. AND however, because the image quality will not affect it (but it will affect the price and convenience), but less important, especially with frequent use. Some cameras are powered by ordinary AA-batteries, which last no more than 30 shots. There are cameras that feed on lithium batteries. Sometimes they are built into the camera that first, awkward in the absence of a number of outlets, and secondly, their lifespan is limited. Some digital cameras are equipped with built-in memory, but usually no more than 20 MB. Therefore, most digital images stored on external memory card. Speed-to arrange any of the existing maps, as rate CPU chamber completely correlated. The advantage of digital cameras have LCD displays. First, they allow you to immediately view the captured image, and immediately remove it from scratch, and secondly, give the opportunity to withdraw from uncomfortable positions, serving as a viewfinder, and third, displays all the camera settings. The undoubted disadvantages include the extra expense is worth the battery. Digital Cameras without flash are not suitable for work in low light conditions. Cheap models are equipped with built-in flash, which is somewhat helpful, but sometimes, conversely, to excessive light. In such cases it is advisable to use Digital camera with external flash plug. The main thing when choosing a digital device to determine the purposes for which you get it. And on this basis to decide what characteristics are important for you.
