The importance of expanding information and making good use of composition

Ernest Haas, an Austrian photographer, has reached the point where there is no sword in his hand and a sword in his heart. He believes: "Composition lies in balance, and everyone handles balance differently."

Just like when Wushu reaches the highest level, there is no name for moves, and it can only be solved by one's own ability. On the position of camera in composition. He believes: "The more you can forget your equipment, the more you can concentrate on your subject matter and composition, so the camera is just a continuation of your eyes and has no other meaning."

Jacobs Jr also thinks: "The most basic factors of composition are lines, forms, textures and the space between these factors. Of course, color is also a factor that cannot be ignored. Convergence lines can generally explain the perspective relationship, but not all photos should show the depth of perspective. Many excellent works are flat patterns.

Portraits of scenes or people in the viewfinder are arranged according to the photographer's personal feelings. Therefore, how to compose a composition, just like how to choose the theme, light and color, can also be the basis of a photographer's unique personal style. ?

In most cases, one or a group of shapes or forms play a leading role in each photo, and the color, volume, position and other shapes in the photo serve as the leading factors. The contrast in composition refers to the contrast between big and small, bright and dark, near and far, active and passive, smooth and rough, rich and light colors.

We should make more use of these opposing factors so that the subject can influence the whole composition through them. For example, if the contrast law is used properly, the photos will have great charm. "Some people may have a gift for composing music.

When the proportion of the subject in the picture is too small, or the blank space of the picture is monotonous (such as shooting a tall building in the sunset), you can creatively use the underexposure to form a silhouette as the foreground. Black silhouette can not only oppress the audience's vision of the subject, but also not distract the audience.

We can even use the silhouette as the main frame to form square, round or varied shapes, so that ordinary scenery has a unique sense of form and increases the depth of the picture.

Two exposure principles: "Better than not" and "Better than not"

The two exposure principles of "better than nothing" and "better than nothing" in photography have different views and many supporters. As the name implies, "overexposure is better than underexposure" means "overexposure is better than underexposure". As long as the exposure histogram does not exceed the right boundary, you can safely overexpose, which will make the picture as clean and delicate as possible, and the higher the sensitivity, the more obvious the effect.

"Better owe than pass" means "Better owe than pass", because the picture is not bright enough caused by underexposure, and PS can be used to make up for it in the later stage, but once overexposed, the details are lost, and it is difficult to solve it with any software.
