Source sentences:
text: The higher the f-stop number = the smaller will be the aperture opening = the deeper the depth of field (less blur effect)
text: The smaller the f-stop number = the bigger will be the aperture opening = the shallower the depth of field (more blur effect)
text: You can also use smaller f-stop to click portraits and macro photos with shallower depth of field (more blur effect).
text: Now you want a shallower depth of field (more blur effect), so you reduce the aperture value to f/2.8.
