What does macro mean?

It's macro photography. Macro photography is a relatively large category in photography activities. It can be said that most people engaged in photography have been exposed to macro photography to some extent. ?

Macro photography is not mysterious, but some photographers have an elusive feeling about this kind of photography, mainly thinking that macro photography is an alternative way after engaging in ordinary photography. In fact, macro photography is an extension of ordinary photography, and its working mechanism is the same as that of ordinary photography, and it must abide by the basic laws of optics.

Extended data:

It is often heard that the lens can take macro effects of 1: 1 and 1: 2, and these ratios refer to the magnification of the lens. The value on the left represents the size of the image on the film plane, while the value on the right represents the size of the actual object. When the lens can reach the magnification of 1: 1, the lens can completely project the real size of the object onto the film plane.

Let's give a simple example: the area of 135 film is 24 mm x 36 mm. If we use a lens that can completely record the subject with the same area of 24 mm x 36 mm on 135 film, the magnification of this lens is 1: 1. We should remember that the larger the number on the left, the higher the magnification. If the value on the right is greater than the value on the left, the magnification will be smaller.
