What does macro mean?

Macro photography, that is, macro photography, refers to the camera shooting an image as big or slightly smaller than the actual object through the optical ability of the lens.

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.

Macro photography is one of the specialties of digital cameras. With macro photography, ordinary scenes can also be made into dramatic scenes. Macro photography is especially good at expressing tiny things such as flowers, birds, fish and insects, and can fully show details. It can also express its creativity at will in topic selection, composition and lighting, unlike taking pictures of scenery, people and folk culture, which are subject to many conditions.

Macros are quick to get started, although they are mostly sketches, but they often contain the good intentions of many authors, and they can also be called fine works.

Macro photography technology;

1, lighting control

When macro shooting, it is necessary to correctly adjust the ratio of natural light and artificial light, and reasonably arrange the light to control the light, which can create different atmosphere and artistic conception.

Don't use the flash of the camera easily, because although the flash of the camera can shorten the exposure time, make the depth of field deeper, and weaken the influence caused by jitter or object movement during exposure, it should be understood that the use of the flash in macro shooting is more difficult than that in ordinary shooting mode, and it is easy to cause overexposure if it is not handled well.

2. Focus selection

Generally speaking, when you take macro photography with a digital camera, you will find that the closer the camera lens is to the object, the bigger the object will be. But if you find the right focus, the photos will be clearer, more vivid and more impressive, especially the tiny creatures such as bees in flowers, worms in grass and predatory ants. Macro photography should pay more attention to the expression in their eyes.

3. Focus and depth of field

In macro photography, the depth of field is often the key to get a good macro picture. Because macro photography is taken very close to the subject, there is little field of vision. Of course, the depth of field of the photos taken is generally shallow, and the background cannot be expressed in most cases. But sometimes in order to make the photos look perfect, it is necessary to strengthen the depth of field appropriately, so special attention should be paid to the adjustment of focal length and depth of field.
