Ask God for help, project the title of this picture, about photography, thank you.

Wide-angle lens is characterized by many things suitable for shooting large scenes, such as scenery photos, but it is easy to deform. Please note that there is no linear reference at the edge of the photo. The characteristic standard of medium focus lens is close to the visual range of human eyes, which is suitable for taking portraits or still life. Because of the small lens distortion, the telephoto feature can shoot distant objects, suitable for shooting sports or wild animals, as well as birds and planes.

Triangle composition is also a composition with the word' well'. Mainly put the main body at any point on the four right angles of the word' well'.

Depth of field has three elements, aperture, object distance and focal length.

Background blur needs to be shot at a large aperture of 1. The person or thing being shot is far away from the background and close to the lens, and the air knife is shot with a telephoto lens.

Same as the second question? The characteristics of standard lenses are close to human eyes, and the lens distortion is small.

M stands for manual gear, A stands for aperture priority, and S stands for shutter priority.

I really don't know much about scenery. I should choose morning or afternoon, because there is a large amount of sunlight at noon, so I really don't know much about not taking scenery films.

Hand to hand combat hopes to adopt
