What is the aperture of tourists' favorite commemorative photos?

Depends on which one you shoot. . When going out to play, you usually take two lenses, one is 18- 135, and the other is 50 1.4 fixed focus. The Jiao Da aperture is generally set at f 1.4- 1.8, which mainly shoots people, special things and flowers. For example, in the seaside, Gulangyu Island and those alleys, the aperture of f 1.4 will take a shallow depth of field, and the background is blurred and very emotional. If you want to release people and scenery, then use a lens with normal focal length and make a good composition, which is also beautiful. . It can also be equipped with a wide-angle lens, shooting people and scenery are all kinds of high-end atmosphere. . So I think this question is not a fixed number, it depends on the scene you are in and your emotional feelings at that time. .
