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 are more or less exposed to macro photography; in fact, macro photography is an extension of ordinary photography, its working mechanism is the same as ordinary photography, must abide by the basic laws of optics.

What do you mean, macro?

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 are more or less exposed to macro photography.

Macro photography is not mysterious, but some photography enthusiasts have a kind of unpredictable feeling about this kind of photography, mainly after engaging in ordinary photography, they think that macro photography is an alternative way, in fact, macro photography is an extension of ordinary photography, its working mechanism is the same as ordinary photography, must abide by the basic law of optics.

Tips:

In macro shooting, the main light control is to correctly adjust the ratio of natural light to artificial light, reasonable layout of light, can create a different atmosphere and artistic conception.

Personally, it is recommended not to use the camera flash easily, because although the camera flash can shorten the exposure time and deepen the depth of field, and reduce the impact caused by the jitter or object motion during exposure, it is important to understand that it is more difficult to use flash in macro shooting than in our normal photography mode, and it is easy to cause overexposure if it is not handled properly.

Extend:

Every day, I often hear that the lens can reach the macro effect 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 of 1:1, that is, the lens can project the true size of the object completely onto the film plane.

Let me take a simple example: the area of 135film is 24mmx36mm. If the lens we use can fully record a subject with the same area of 24mmx36mm on 135film, this lens will have a magnification of 1:1. We should keep in mind that the larger the number on the left, the higher the magnification, and the magnification at 2:1 will be higher than 1:1. If the value on the right is larger than that on the left, the magnification is smaller.

This is the end of what is Macro. Thank you for your reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
