How to use line expressive force in photography.

Lines can act on the overall structure of the picture and the overall posture of the main image. No matter what natural phenomena are seen in the sea, forest, mountains and deep valleys, they can choose horizontal, straight, curved and oblique line forms according to their characteristics and play a major role in the picture structure.

Lines can create a different sense of texture, quantity and space by depicting details such as subject, companion and background.

Lines also play an important role in creating the melody, rhythm and artistic conception of a work.

Line is not an objective entity, but only the contour lines of various objects formed by the action of light, the lines formed by dividing lines of different shades and too many color blocks, and even the nonexistent human vision and intermittent fuzzy dotted lines. Most of these different lines can only be seen later in the work. If you don't carefully analyze, observe and experience when you are engaged in photography creation activities in real life, you may ignore or be unaware of the existence of lines. So you can train the photographer's eyes and make full use of lines to complete the composition.
