Exercise 3 -Focal length and angle of view

continuing the theme from exercise 2, this time the task was to focus on the same object in a scene with a depth but change apertures while taking a set of photographs. the ceramic houses were still only desk so here we go again…

same lens as at exercise 2 used…

1. focus on the fourth house in the row, f2.8

this photo was taken with the widest aperture, and all houses in front and behind the fourth house were blurred as a result. shallow depth of field.

2. focus on the fourth house in the row, f8.0

this photo was taken with the aperture set at the mid -point. blurred house in the front of the row but more sharpness for the houses at around the focus point ( =the fourth house).much bigger depth of field.

3. focus on the fourth house in the row, f22

the smallest aperture setting resulted in all of the houses being sharp ( except the first one, which is slightly blurred ) so the biggest depth of field.

conclusion : photographing the same object with different aperture gives different depth of field and therefore gives different level of sharpness to the photograph

exposure – reciprocal relationship between aperture and shutter speed
