Background defocus 
 
This control effectively gives you direct access to the aperture control. As 
we know selecting a large aperture (smaller f stop number) gives us 
shallower depth of field (DOF) making the background blurred, or 
defocused.  
 
The slider control shows the icon of a head and distant mountains, by 
default the camera selects the wide open f2.8 aperture to give the most 
defocused background as you use the navigation buttons, or turn the 
back control dial, you can move the slider to the right. Here the icon 
shows the mountains more clearly – the result of selecting a smaller 
aperture with more DOF. In essence this control allows you to select f2.8 
to F8. 
 
Color tint 
 
This adjustment allows you to add 
some color bias to the image.
 
Moving 
the indicator slider to the left
 
adds 
some warmth to the image whilst 
moving it to the right will add blue to 
the image and make it
 
appear cooler.
