Aperture and the Relationship to Depth of Field
+Lower f/stop = shorter depth of field
+
Aperture set at 4.5 f/stop
+
Aperture set at 5.6 f/stop
+
Aperture set at 7.1 f/stop
+Higher f/stop = deeper depth of field
+
Aperture set at 9.0 f/stop
+
Aperture set at 11.0 f/stop
+
Aperture set at 14.0 f/stop
+
Aperture set at 18.0 f/stop
+
4.5 f/stop 18.0 f/stop
+
Aperture set at 3.5 f/stop
+
Aperture set at 4.5.0 f/stop
+
Aperture set at 5.6 f/stop
+
Aperture set at 7.1 f/stop
+
Aperture set at 9.0 f/stop
+
Aperture set at 14.0 f/stop
+
Aperture set at 18.0 f/stop
+
Aperture set at 22.0 f/stop
+
22.0 f/stop 3.5 f/stop
+
But why would I want blurred or
non-blurred backgrounds?
+
CREATIVE CONTROL!!
+
Perhaps you want everything in focus…
+ Like this…….
+ ….or this.
+Or perhaps you want
just your main subject in focus, and other
things blurred.
+
Like this…..
+
Or this…..
This blurred background
is also referred to as “Bokeh.”
+So…..Low f/stop number equals short depth-of-field, which equals sharp focus on the main subject and blurred backgrounds.
+Large f/stop number equals long depth-of-field, which equals focus on all elements in the picture frame and limited or no blurriness.
