How does a SLR camera shoot objects without blurring the foreground?

That is, the background does not need to be blurred. This requires comprehensive consideration of three aspects: aperture value, lens focal length and the distance between the photographer and the subject (object).

1. If the distance between the photographer and the subject (object) is very close, rotate the focal length to a wide angle and set a small aperture of more than 8 to ensure a clear background.

2. If the photographer is far away from the subject (object), the background will be clearer without pulling the focal section too close, basically no matter what aperture value is used for shooting.

3. If possible, try to preview the depth of field, or visually observe the depth of field effect through screen capture.

Simply put: don't stand too close to the subject, and don't pull the lens too close to the subject. If the aperture is above 5.6, the background will be clear. If it is not clear, please move the aperture to 22.
