This is called antialiasing (antialiasing) or smoothing and is necessary to prevent moiré-striped artifacts that can occur when photographing fabrics and other items that have a periodic, repetitive structure.

But when either the camera or the subject is in motion, choosing the appropriate shutter speed becomes not only a technical but also an artistic task.
Not to get confused: the higher the shutter speed, the shorter the exposure time than a shutter speed lower the shutter speed longer. Continue reading
