一、数字式照相机的用途 传统的照相机用胶片记录被摄物,胶片经显影定影和冲洗后获得底片。印刷制版时,底片或照片要经过电子分色再拼入图文版面。数字式照相机则不用胶片,被摄物在特殊的照相机后盖上成的像经电荷耦合列阵直接转换成数字式信息。它可以存储在磁盘中,也可以联机输入电脑进行拼版,不但省却了胶片的化学处理,而且省时省钱。数字式照相机的光阀值是无级调控的,影像的动态范围扩大使摄影家的创作天地更加广阔。 First, the use of digital cameras Conventional cameras with film recording of the subject, the film after developing and fixing the film obtained after washing. Printing plate, the negatives or photos to go through the electronic color separation and then into the graphic layout. Digital cameras do not use film, the subject in a special camera back cover into a charge-coupled array directly into digital information. It can be stored on disk, or it can be typed into a computer online to dispense with the chemistry of the film, saving time and money. Digital camera light threshold is infinitely adjustable, the dynamic range of the image to expand so that photographers create a vast world of creativity.
