What does macro mean?

Macro refers to: macro photography.

Macro photography is a relatively large category of photography activities. It can be said that the vast majority of people engaged in photography activities have been exposed to macro photography to some extent.

Macro photography is not mysterious, but some photography enthusiasts have an elusive feeling about this type of photography. Mainly because after engaging in ordinary photography, they think macro photography is an alternative method. In fact, Macro photography is an extension of ordinary photography. Its working mechanism is the same as ordinary photography, and it must abide by the basic laws of optics.

Tips:

When doing macro photography, the main thing to control the light is to correctly adjust the ratio of natural light to artificial light and arrange the light reasonably. , can create different atmospheres and artistic conceptions.

Personally, it is recommended not to use the camera flash easily, because although the camera flash can shorten the shooting exposure time and make the depth of field deeper, it can reduce the impact caused by jitter or object movement during exposure, but What you need to understand is that the use of flash during macro photography is more difficult than in our normal photography mode. If it is not handled well, it can easily cause overexposure.

Extension:

We often hear that lenses can achieve macro effects of 1:1 and 1:2. 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 subject. When the lens can achieve a magnification ratio of 1:1, that is, the lens can completely project the true size of the object on the film plane.

Let’s take a simple example: the area of ​​135 film is 24mmx36mm. If the lens we use can completely record a subject with the same area of ​​24mmx36mm on 135 film, this lens will have a ratio of 1:1 The magnification ratio, you should remember that the larger the number on the left, the higher the magnification factor, and the magnification ratio of 2:1 is higher than that of 1:1. If the value on the right is larger than the value on the left, the magnification is smaller.
