compromise is not ideal for<br />

Infrared trigger<br />
Technically, we could simply<br />
c<strong>on</strong>sider <strong>the</strong>se to be a special<br />
type of light-sensitive trigger,<br />
as infrared is simply ano<strong>the</strong>r<br />
frequency of light that happens<br />
to be invisible to humans. The<br />
similarity ends <strong>the</strong>re, though:<br />
most infrared triggers are highly<br />
intelligent. They allow both <strong>the</strong><br />
camera and <strong>the</strong> flash to measure<br />
<strong>the</strong> scene, think about what each<br />
sees from its viewpoint, and<br />
agree with each o<strong>the</strong>r about what<br />
<strong>the</strong> camera is going to do and<br />
what <strong>the</strong> light is going to do.<br />
These are expensive, but some<br />
of <strong>the</strong> cost is reduced by not<br />
having to buy a separate device.<br />
The system may be ideal for (1)<br />
absolute novice photographers<br />
who want as much automati<strong>on</strong><br />
as possible so <strong>the</strong>y d<strong>on</strong>’t<br />
have to spend a lot of study<br />
time and (2) highly experienced<br />
photographers who want <strong>the</strong><br />
system to take over a lot of <strong>the</strong><br />
The infrared trigger<br />
<strong>on</strong> this flash<br />
not <strong>on</strong>ly triggers<br />
<strong>the</strong> flash, but it<br />
can communicate<br />
intelligently<br />
with <strong>the</strong> camera<br />
for remote<br />
power<br />
adjustment.
