Generally, mobile phone photography has an aperture. Is the aperture bigger or smaller? !

We know that if the aperture is large, we will get more light and shallow depth of field background blur effect, which can simplify the clutter of the picture and make the subject more prominent. So, is the larger the aperture, the better?

The answer is definitely no, depth of field has different uses for different subjects.

1, macro is more suitable for small and medium aperture.

Macro photography, we will see that the background blur is very soft, many beginners will think that this is the effect brought by large aperture, but the fact is that macro is more suitable for small and medium aperture. Because macro photography uses extremely short shooting distance and medium-long focal length (for example, 100 micron 100mm) in the three elements of depth of field, the range of depth of field becomes very small. If the aperture is enlarged again, the range of depth of field may be only a few millimeters, which is inconsistent with the photographer's purpose of clearly recording the macro subject characteristics.

Therefore, in macro photography, the aperture is generally set to a small aperture to obtain a wider range of depth of field, so as to clearly record the characteristics of macro subjects.

2. Commercial photography should have sufficient depth of field.

When shooting a portrait, shooting with a large aperture will make people look better, because the background such as sundries is blurred and the subject of the portrait is more prominent. Therefore, in the process of taking portraits, if the aperture is enlarged, more accurate focusing and composition arrangements are needed, so that the photos taken will be ok and the corresponding operation steps will be more complicated.

So a large aperture can bring a good amount of light and blur the background, but the larger the aperture, the better. In macro photography, commercial photography and other fields, small and medium aperture will be more suitable. If time permits, you can be patient, and the photos you want to take are straight, etc., and you can deal with the depth of field in the early stage. After all, large aperture shooting is easy to make mistakes, so it depends on your shooting habits.
