Canon 5D Mark III Experience 
 

to confidently use the ones that turn your Canon 5D Mk III into an image capturing tool 
that works best for you and the photographic situations you work in. 

1.1 Take Control of Your Camera 

Since the camera is a tool to take the images you want to take, you obviously can’t 
always allow the camera to make decisions for you.  You have to take control of the 
camera to ensure that you capture exactly the images you intend - by autofocusing 
precisely where you want, setting the aperture or shutter speed that you want, and 
obtaining the exposure you want.  While the 5D Mk III is an intelligent camera, it cannot 
read your mind and your intentions and does not know that you wish to focus on and 
properly expose the small blossoms in the foreground, while making the background 
appear out of focus, and the branches to be caught still and not be blurred from the 
motion of the wind, on this bright, sunny day (see Figure 2).  You have to tell the 
camera to do all of this, through the various controls and settings, such as the autofocus 
AF Mode and AF Area Selection Mode (focus on the blossoms), the Exposure Metering 
Mode (properly expose the blossoms), the Aperture setting (the out-of-focus 
background), the Shutter Speed (freezing the motion of the branches), the ISO (bright 
day) and the White Balance (sunny day).
