Today mainly tried the role of high and low shadows in the process of still life photography and the daily considerations.
White objects on a white background is the high long tone is generally rarely used to shoot still life (usually more inside the landscape photography) The main body can reflect the feeling of clean and pure but bright color ceramics are not suitable. The edge of the main masking or it is easy to melt into the white background Black is the opposite.
White objects on a black background is low and long tone Can achieve the effect of highlighting the subject. Also pay attention to the edge line.
白底白色物体就是高长调 一般很少用来拍摄静物（通常风光摄影里面比较多） 主体能体现出干净和纯粹的感觉但明亮色系陶瓷不适合。边缘主要遮挡不然很容易融到白色背景中去 黑色则相反。
