Luxi review: Let your iPhone double as your camera's light meter

<p>Serious photographers sometimes spend hundreds of dollars on an incident light meter–a small handheld device that measures the light falling on the subject. <a href="http://www.esdevices.com/" target="new">Luxi[/url] is a $30 iPhone accessory that promises to do the same job using just your existing phone.</p>

<p>The Luxi device fits on a caseless iPhone 4, 4s, 5,or  5s.</p>

<p>Why do some photographers carry a separate light meter when there’s a perfectly good one built into their camera? In a nutshell, it’s because standalone incident light meters are more accurate over a wider range of photographic situations. That’s because they measure the light falling on the subject from the direction of the camera, not the reflected light that bounces back into the camera.</p>

<p>Luxi calibrates the light and then advises you on aperture, shutter speed, and ISO.</p><p class="jumpTag"><a href="/article/2083994/luxi-review-let-your-iphone-double-as-your-cameras-light-meter.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
