Q&A
Depth of field is the depth of the object space in which a clear image can be obtained on the image plane. That is, there is still a clear range of imaging before and after the focal point of the object being photographed, which is the depth of field. In other words, the object being photographed is within the range of the front and rear depth of field.
Main factors of depth of field
Lens aperture
The larger the aperture, the smaller the depth of field; the smaller the aperture, the larger the depth of field.
Lens magnification
The larger the magnification, the smaller the depth of field; the smaller the magnification, the larger the depth of field.
