Is the aperture larger or smaller?

For camera lens, the larger the aperture, the better (large aperture is beneficial to improve the shutter speed in dark environment).

However, when actually taking landscape photos, it is often set to a small aperture. Generally, digital SLR is set to F 1 1 or F 16, so it is not appropriate to set it to the minimum value (the minimum value is not good for imaging). For consumer-grade DC, the minimum aperture is not too small (a small DC lens has a short focal length, so it is very difficult to make a small aperture, and the minimum aperture is generally F8 or F 1655).
