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.
Quality of the image depends largely on the matrix - a unit with a definite amount of photosensitive elements (pixels). It is responsible for color rendition, noise, transmission of small details, and depth of field. The amount of pixels does not always correspond to the obtained 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 not suitable for use in low light conditions. Cheap models are equipped with built-in flash, which is somewhat helpful, but sometimes, conversely, can give an excessive light. In such cases it is advisable to use digital cameras with a pluggable external flash.
The main thing when selecting a digital device is to determine for what purposes you acquire it. And on this basis you have to decide what characteristics are important for you.
