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.
