I took two photographs of these Playmobile characters standing on a log. In the first one I focused on the face of the one on the right. The f-stop was 5.6 so the dof was very shallow, even the character on the left is slightly out of focus. The second photograph was taken with the focus on infinity.
Both photographs were set as follows: f-stop 5.6, shutter 1/125 sec, ISO 200, focal length 80mm.
These examples show how the eye is drawn to the focus area, in particular to the face on the right hand character. However, when looking at the right hand photograph the two characters are almost non existant, as the eye tends to ignore them.
