Aperture control
24
The aperture control provides you amazing versatility to produce mes-
merizing depth of field. A larger aperture (f/5.6) draws the viewer's
eyes to the main subject and blurs the background with a pleasing
aesthetic quality.
Bokeh refers to the magical out-of-focus blur rendered by a shallow
depth of field. In general, the larger the aperture, the shallower depth
of field. However, if you want everything to be in focus, choose a
smaller aperture (f/22).
Bokeh
Rotate the aperture wheel until the sign "star" is shown. Now you
are in Bokeh mode where you have a shallow depth of field.
Go out and look for some distinctive background lights such as LED
or Christmas lights. Get close to your subject and put some distance
between your subject and the background lights and take a picture.
