摄影是用光作画。光线不仅是摄影中确定曝光组合的依据,而且是一幅摄影作品的影调、色彩、意境、主题等诸多方面的决定性因素。所以摄影家对光线的选择和运用,便成为一项不可忽视的基本功。 Photography is done with light. Light is not only the basis for determining the exposure combination in photography, but also the decisive factor in many aspects such as the tone, color, mood and theme of a photographic work. Therefore, the selection and application of light by photographers has become a basic skill that can not be ignored.
