Buying a Digital Camera. A Few Tips.
Choosing a digital camera as other equipment is done by examining its technical characteristics. It will not be superfluous 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 we will discuss the technical characteristics, as they determine if the camera will be able to give you a colorful picture.
There is a belief that the more pixels, the better the image quality is. It is not right and leads astray a lot of people. This characteristic is responsible for a maximum resolution of the photo that you can make by a digital technique without losing quality. It is crucial to take into account the size of the matrix, on which there are these pixels. That is why an amateur camera may have more megapixels than a professional one.
Picture quality depends on the matrix - a unit with a certain amount of photosensitive elements (pixels). It is responsible for color rendition, noise, transmission of small details, and depth of field. The number of pixels does not always correspond to the resulting image.
A serious approach must be to the choice of optics. First of all, look at such an option, as zoom: it may be digital or optical. Good photo cameras have both, but cheap cameras have only a digital zoom. Digital zoom is implemented by increasing the shot after the shooting and cutting it to the needed size, thereby losing quality. The optical zoom is realized by using the change of focal distance of the objective lens.
Digital cameras without flash are inapplicable for use in low light conditions. Cheap models are equipped with integrated flash, which is somewhat helpful, but sometimes, conversely, can give too much light. In such cases it is expedient to apply digital cameras with a pluggable external flash.
The main thing when choosing a digital device is to determine for what purposes you buy it. And on this basis you should decide what characteristics are important for you.
