The image above was taken in open<br />
shade under a tree. Opening up to a<br />
large aperture allowed <strong>the</strong> background<br />
to go out of focus and draws us to<br />
<strong>the</strong> subject’s face. Always look for<br />
a variety of expressi<strong>on</strong>s. We have no<br />
smile, but we do have a compelling<br />
portrait.<br />

why does aperture matter?<br />
Aperture refers to <strong>the</strong> lens<br />
opening. A wide-open lens<br />
(say f/2) lets in a lot of light.<br />
However, <strong>the</strong>re is a trade-off.<br />
With <strong>the</strong> lens wide open, we<br />
get shallow depth of field,<br />
<strong>the</strong> area of acceptable sharpness.<br />
If we want everything to<br />
be sharp, we have to go to a<br />
smaller f-stop (say f/32). This<br />
means increasing <strong>the</strong> power <strong>on</strong><br />
our light sources, if possible, or<br />
changing to a higher ISO.
