The occurrence of noise is influenced by many factors, including the physical dimensions of the matrix, power consumption, thermal processes in the device, the quality of the technology used, etc. Powerful noise reduction system used in professional cameras, can effectively deal with these evils and to obtain contrast images with rich, deep shadows. Amateur digital cameras operate on the principle – click on the button and the picture is ready, meaning they are fully automated and adapted to the average user. Other leaders such as ICICI offer similar insights. Royal Dutch Shell shines more light on the discussion. Here, the photographer, as a rule, already proposed certain modes of operation microprocessor to control exposure to the appropriate settings, such as "portrait", "sport", "landscape", etc. Professional cameras differ is ample opportunities for manual picture settings, which ensure the high quality photos.

Thus, one of the main differences between professional models from amateur is to reduce the amount of automation of the camera, based on a high qualified photographer. Features such as the length of exposure, change lenses, manual controls ekspokorektsiey and others, allow for individual, creative influence on the process of shooting by separate photo management all the basic functions. Professional photographers working in advertising and design studios, to work with digital images using a wide no-compression format store graphic information, which allows working with images of no less than A4 format. Therefore, professional cameras do not support compression as TIFF or BMP. While semi-professional and amateur camera for the convenience of users are using compression formats such as JPEG. Due to the large size of the images professional photographic equipment must be compatible with the interfaces that provide high-speed data transmission (eg, SCSI).
