Before purchasing a digital camera, take thought for what purpose you will apply it. If it is needed to illustrate your page on the network, the camera with low resolution will be enough for you. But if you're going to make prints from received images, in order to get high-quality photos, you will need a camera with high resolution. Four major factors have a crucial influence on your digital camera:
- Resolution
- Method of operation of CCD
- An optical device of the camera
- Software that "works" with the shot.
Resolution is determined by the number of light-sensitive diodes on the surface of the CCD. For instance, if the instruction says that it has a resolution of 1600X1200 pixels, this means that the CCD has about 2 million diodes on its surface. Each of three various diodes on the surface of the matrix can write data about one of the main colors. In order to get data about the color of each pixel, we have to know information about the illumination of at least three diodes. This reduces the actual number of pixels to three times. Instead it the software is applied that allows you to put an equal sign between the number of pixels and the number of diodes.
Though the statement "the more pixels, the higher the resolution, the better the shot" basically is true, however, other factors have a significant influence on the quality of the image. So, the quality of the production of the CCDs is very important. The more qualitative made the matrix, the less it will have broken diodes (the size of one diode is about 7.5 microns) that will directly affect the quality of shots.
Unfortunately, the quality of the CCD cannot be described by any numbers or categories, therefore only a careful comparison of diverse models guarantees acquiring the best camera. Concentrate on the field, clarity of the visible picture. If you are satisfied with the quality of the picture, then test the camera under various lighting conditions. Ask also, if possible, to print the captured picture; it will give you more information about the CCD.
