Point
of focus is on background - and with the aperture set at f4 or
wide open this leaves the tree in the foreground out of focus.
|
|
Here the point of focus is still
the grass at the background but with an aperture of f22 both the
grass and the tree are in focus. |
|
While
the aperture is still at f22 the point of focus has been shifted
to the tree in the foreground. |
|
With
the focus set on the tree and the aperture set wide open to f4
the background becomes out of focus. |
