Reducing the aperture on a camera
(a) reduces the depth of field and requires a longer exposure time
(b) reduces the depth of field and requires a shorter exposure time
(c) increases the depth of field and requires a longer exposure time
(d) increases the depth of field and requires a shorter exposure time
(e) does not change the depth of field and requires a longer exposure time (f) does not change the depth of field and requires a shorter exposure time
