A problem of photography technology

The main difference lies in the depth of field and the clarity of the image. First of all, a large aperture will inevitably bring a shallow depth of field. In other words, only around the focal plane is the clearest. The large depth of field brought by a small aperture can be used to shoot scenery. Secondly, long-term shutter exposure requires stable handheld or tripod shooting. For shorter shutter time, hand-held shooting is more convenient. For flash and synchronization problems, shutter speed also has an impact.
