Photography is a mixture of science and art. As an art, it follows the same aesthetic laws as other art categories. As a science, it has technical content that other art categories do not have, and shows the originality of images. It can be said that photography depends on the progress of technology, but only when technology is endowed with aesthetic interest by photographers can it show artistic and moving courage. The basic requirements of photography creation: first, the subject matter should be distinct. When you pick up the camera, there will always be an idea in your mind, whether it is photographing people, flowers and trees, or daily life. This idea is the theme of digital photography. Moreover, an excellent digital video work must clearly present the theme on the screen through the lens; Secondly, we should highlight the subject, and highlight the theme by contrast between reality and reality, or the subject occupies a relatively large proportion in the picture; The third thing to note is that the picture should be simple. Remember that photography is a subtraction art, so the way to make the picture simple is to shoot on the top of the head or overhead, use a telephoto lens, and shoot against the background of morning fog and rain. The fourth point is to meet certain technical standards, because technology is the premise of art; The fifth point is the present image; Sixth, arouse people's feelings.
