Choosing a digital camera as other technique must be done by studying its technical characteristics. It is advisable to hear feedback of present owners of cameras, as well as to compare the stills made by various cameras at the same time in the same place. But now we will consider technical characteristics, as they determine whether the camera will be able to give you a colorful image.
You may hear a view that the more pixels, the better the picture quality is. It is a mistaken belief and misguides plenty of persons. This characteristic is responsible for a maximum resolution of the image that you can make by a digital technique without losing quality. It is crucial to pay respect to 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 has to be to the selection of optics. In the first place, look at such an option, as zoom: it may be digital or optical. Good photo cameras have both, but low-price cameras have only a digital zoom. Digital zoom is implemented by increasing the still after photography and cutting it to the necessary size, thereby losing quality. The optical zoom is realized with the help of change of focal distance of the objective-glass.
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.
