Project 3 - focus with different apertures

Here I took 3 photos of the same scene with 3 different apertures: wide, middle and small.

Photo no.1: wide aperture, F-no:5.0


Photo no.2: mid aperture, F-no: 8.0


Photo no.3: small aperture, F-no:22



For compering the 3 photos I chose the flower in the right-down corner as a point and looked at his edges.
I can see a difference between the widest and the smallest aperture photos as well as in the mid and smallest ones. there is hardly any difference between the first and second.
