<p class="MsoNoSpacing"]Hi,
<p class="MsoNoSpacing"]Can anybody tell me the differences between the &ldquo;Metering
Mode&rdquo; on the Canon EOS 550D.<span> On the
camera you can choose between:
<p class="MsoNoSpacing"]<span><span>-<span>
Evaluative metering
<p class="MsoNoSpacing"]<span><span>-<span>
Partial metering
<p class="MsoNoSpacing"]<span><span>-<span>
Spot metering
<p class="MsoNoSpacing"]<span><span>-<span>
Center-weighted average metering
<p class="MsoNoSpacing"]
<p class="MsoNoSpacing"]When do you change your metering mode?
