The small aperture used to shoot still life is so dark, how should I adjust it?

In fact, this is not based on the object to be photographed.

First of all, the larger the aperture value, the smaller the actual opening. The picture is the aperture part of the lens, and the red circle is the aperture. The size is the part that remains transparent after being covered by the metal sheet.

The so-called large aperture is actually a small transparent part and a large aperture index.

For example, the aperture index is 2.8 and 5.6, and the opening is actually 2.8 and 5.6.

However, to get a fully exposed photo, the luminous flux is the same, so the larger the aperture, the shorter the exposure time.

The exposure time will affect the depth of field of the photo. The longer the exposure time, the deeper the depth of field. That is, the longer the distance of the clear object behind can be.

Therefore, in actual shooting, we still need to adopt different shooting methods with different depth of field according to our own understanding of photos.

Generally, in order to highlight the key points, we can use the method of "big aperture" (here, big aperture means that the aperture is really bigger) to shorten the depth of field and blur the background, so that we can highlight the key points.

Taking pictures is definitely a science. In fact, photographer Peng Zhong often regards aperture as a difficult point. Even if the choice of aperture is actually just a small skill in shooting, it can achieve excellent expressive force if used well.

This is a photo that uses an ordinary mobile phone, but uses the weak light before sunset to achieve a large aperture effect:

Shooting a landscape or panorama requires depth of field. At this time, a small aperture and a large exposure time are needed.
