			<content:encoded><![CDATA[<p>So, after reviewing the shots from my previous exercise, I decided to make a few tweaks.</p>
<p>Andy&#8217;s hacked LED flashlight (the man stuck an 18650 Li-Ion cell inside a $2.99 keychain LED flash.  God that thing is bright) worked pretty decently in the previous light painting exercise, so I figured I&#8217;d up the fire power.  Ran to Harbor Freight during lunch and picked up a 1 million candlepower flashlight for $12.99.</p>
<p>First try was to set the camera&#8217;s white balance to tungsten (since that&#8217;s what flashlights are), camera on a tripod, f/8, ISO100, bulb mode, and lock the shutter open in a dark room.  For the sake of learning, I painted one side of the car at a time:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4388364474" title="View 'Lighting_Mazda5-1' on Flickr.com"><img border="0" width="" alt="Lighting_Mazda5-1" src="http://static.flickr.com/2748/4388364474_9c44aba6aa.jpg" height=""/></a></div>
<p>Here&#8217;s the front of my car</p>
<p>And the sides:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387608481" title="View 'Lighting_Mazda5-2' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-2" src="http://farm3.static.flickr.com/2784/4387608481_0806cca998.jpg" height="333"/></a></div>
<p>And here&#8217;s the combined shot:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387614675" title="View 'Lighting_Mazda5-3' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-3" src="http://farm5.static.flickr.com/4016/4387614675_bb59e795fd.jpg" height="333"/></a></div>
<p>There is some spillage of the light cone.  Basically the parabolic reflector throws a pretty tight beam spot, but there&#8217;s some secondary reflection / refraction off the front lens cover that&#8217;s lighting up stuff I don&#8217;t care to light up.</p>
<p>A quick trip to the mail room for an envelope or two, and a bit of packaging tape, solved that problem:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4388423446" title="View 'Lighting_Mazda5-13' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-13" src="http://farm5.static.flickr.com/4024/4388423446_57a65d63fe.jpg" height="333"/></a></div>
<p>Results:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387617517" title="View 'Lighting_Mazda5-4' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-4" src="http://farm3.static.flickr.com/2755/4387617517_0f26e17fb4.jpg" height="333"/></a></div>
<p>Next, I set up my Photek softlighter with the secondary diffuser, and hoisted it up high on my light stand.  I really need a sturdier stand, or something with a counterweight to help hold this up.  By lighting from up high, I am hoping to eliminate the hot spot on the bodywork.  Something to do with family of angles and stuff. <img src='http://TerenceTam.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> .</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387622351" title="View 'Lighting_Mazda5-5' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-5" src="http://farm3.static.flickr.com/2733/4387622351_cddb0107c3.jpg" height="333"/></a></div>
<p>HEY!  This is pretty good.  Of course, a softbox is kinda like a shotgun approach to lighting, but at least there&#8217;s a choke in this shotgun barrel.</p>
<p>One thing to note (if you zoom in on the original) is that the light stand holding up the Photek Softlighter is visible in the shot.  It&#8217;s being back-lit by the softlighter, and shows up as black lines in the reflections in the window.</p>
<p>I fixed this by installing the diffuser the &#8220;wrong&#8221; way.  Normally I don&#8217;t do this, as it eliminates the ability to tilt the softlighter and blocks off the flash&#8217;s controls, but for what I&#8217;m doing here, it solved my problem nicely:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4388432696" title="View 'Lighting_Mazda5-14' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-14" src="http://farm3.static.flickr.com/2601/4388432696_a7b63af828.jpg" height="333"/></a></div>
<p>I moved the car to shoot the driver&#8217;s side.  While there, I also popped just the hazard lights by themselves, to give an idea of their contribution independently in the final image:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4388385650" title="View 'Lighting_Mazda5-6' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-6" src="http://farm5.static.flickr.com/4063/4388385650_1336b07d7f.jpg" height="333"/></a></div>
<p>With the &#8220;gimpy&#8221; configuration on the softlighter, I retry the overhead lighting:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4388390504" title="View 'Lighting_Mazda5-7' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-7" src="http://farm3.static.flickr.com/2771/4388390504_6c07991c33.jpg" height="333"/></a></div>
<p>Not bad, but the sides are a bit dark.  By the way, the strobe is at M1/16 and I&#8217;m firing 2-3 shots per second while slowly walking down the side of the car.  Essentially turning my 60&#8243; photek into a virtual, 8ft x 60&#8243; strip lighting softbox.  That&#8217;s powered by 4x AAs <img src='http://TerenceTam.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
<p>Another shot, this time using a 70-200 for a tighter crop and less background clutter:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387632709" title="View 'Lighting_Mazda5-8' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-8" src="http://farm5.static.flickr.com/4050/4387632709_616e270a0f.jpg" height="333"/></a></div>
<p>Looking nice.  Need to do something about lighting the front surfaces though.</p>
<p>Here, after lighting the top and across the hood, I walked sideways across the front and held the softbox out to the side, aiming straight at the car.  </p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387638195" title="View 'Lighting_Mazda5-9' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-9" src="http://farm5.static.flickr.com/4065/4387638195_eb06049d2b.jpg" height="333"/></a></div>
<p>Ooops, ended up in the camera&#8217;s field of view.  The edge of the photek lights up from secondary bounce; so I have to be extra careful.  The next time around I&#8217;m going to try to find a proper softbox, and probably put a cardboard grid on it to control the spread more.</p>
<p>Now that I have a better understanding, I reshoot the sequence, being mindful to stay outside the camera&#8217;s field of view at all times with the side firing softbox:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387644237" title="View 'Lighting_Mazda5-10' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-10" src="http://farm3.static.flickr.com/2694/4387644237_3fe06031af.jpg" height="333"/></a></div>
<p>Straight out of camera, vantage point 1</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387651935" title="View 'Lighting_Mazda5-11' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-11" src="http://farm5.static.flickr.com/4047/4387651935_9d0a720fb6.jpg" height="333"/></a></div>
<p>Straight out of camera, vantage point 2</p>
<p>To get the camera low enough for the second shot, I twisted the Manfrotto tripod around like a pretzel:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387683169" title="View 'Untitled' on Flickr.com"><img border="0" width="500" alt="Untitled" src="http://farm5.static.flickr.com/4038/4387683169_da9677cfe7.jpg" height="375"/></a></div>
<p>And with a bit of editing in Lightroom:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4388444690" title="View 'Lighting_Mazda5-12' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-12" src="http://farm5.static.flickr.com/4068/4388444690_e0b79a92b8.jpg" height="322"/></a></div>
<p>The only mistake?  I got into the car to flick on the hazards, HID lights and fog lights.  The suspension reacted accordingly, so there is a mismatch where the side turn indicator lit up, versus where the indicator lamp sat during nominal exposure.  Nuts.</p>
<p>I think I&#8217;m at the point where I&#8217;ve outgrown this warehouse &#8211; the white walls really distract from the final image, but it offered me a nice, warm and dry place to practice my light painting.  By the way, here&#8217;s a behind the scene shot of the &#8220;studio&#8221;:</p>
<div style="text-align:center;"><a href="http://www.flickr.com/photos/8812323@N08/4387678291" title="View 'Lighting_Mazda5-15' on Flickr.com"><img border="0" width="500" alt="Lighting_Mazda5-15" src="http://farm3.static.flickr.com/2678/4387678291_8736bbe0ed.jpg" height="333"/></a></div>
<p>Total time:  About 3 hours, after work, for about 20 images.  And a lot of head scratching.  </p>
<p>Now, I need to location scout for an outdoor place that&#8217;s got low ambient light&#8230;</p>
