<h3>Overview</h3>
<p>Night photography is one of my favorite branches of the photography tree. It is not<br />
your standard shots: long exposures at night allow for surprises and interesting effects;<br />
lighting is provided by the moon or artificial; plus numerous other unknown factors<br />
(such as airplanes) all play into night photography. </p>
<p>Here&#8217;s a few tips and things I&#8217;ve picked up while shooting night photography. Hopefully it<br />
is helpful to you and encourages you to get out there and shoot. Sometimes the dark of night<br />
is the only free time we can find for ourselves and photography.</p>
<p></section></p>
<p><section></p>
<h3>Most Important</h3>
<p><a href="/photo/blog/index.php?p=65"><img src="/photo/blog/thumbs/2005_C01_07.jpg" border="1" align="right" style="margin: 8px"></a></p>
<p>In my mind, the two most important things for night photography is:<br />
    (1) <b>Warm clothes</b> and (2) <b>Food and Drink.</b> If you are hungry or cold you aren&#8217;t going<br />
    to be motivated to stand out there and shoot 20 minute exposures.</p>
<p>Ok, so we aren&#8217;t hungry or cold, so next, you should probably have a<br />
    camera and film/memory/batteries. Digital or film doesn&#8217;t matter much, what<br />
    is really important is Bulb, or long exposure settings on your camera.  Many<br />
    small point-and-shoot digital cameras are limited to this respect. My Canon S410&#8217;s<br />
    longest exposure is only 15 seconds, barely adequate for anything but bright lights. </p>
<p>Another great thing, but not necessary, for night photography is a comrade photographer.<br />
    Some one to give you a little extra encouragement to get out, to stand with you and chat<br />
    with during the long exposures, another vision and set of ideas. Plus having some one else<br />
    there gives you a sense of security in the dead of night, especially if you are in shady<br />
    neighborhoods where all the great shots hide.</p>
<p></section></p>
<p><section></p>
<h3>Technique &#8211; Handheld Night Photography</h3>
<p>A tripod is also pretty important, but as these handheld shots show, you don&#8217;t always<br />
    need one. The following three shots were at Times Square, handheld, four second exposures:</p>
<table width="95%">
<tr>
<td align="center" width="33%">
        <a href="/photo/blog/index.php?p=103"><img src="/photo/blog/thumbs/2005_C07_15.jpg" border="1"></a></p>

    </td>
</tr>
</table>
<p></section></p>
<p><section></p>
<h3>Technique &#8211; Exposure Time</h3>
<p>One of the hardest parts of night photography is getting the exposure close, let<br />
    alone getting the right exposure.  Numerous factors come into play from light source:<br />
    moon, artificial, reflections; to film type and reciprocity.<br />
    A big advantage for digital cameras is being able to see what you captured immediately,<br />
    which at least gives you an idea if you&#8217;re in the right ballpark.</p>
<p>I have an exposure calculator and write up on <a href="moonlight.html">Exposures for Moonlight Photography</a>.<br />
    However this only covers the instances when you are taking pictures only by the light of the moon,<br />
    this does not cover any city shots, or weird combos of artificial light and moonlight.</p>
<p>The single greatest method to get the right exposure is: practice, practice, practice; and<br />
    take good notes. Usually all I record is the subject and exposure time. I normally shoot night<br />
    stuff at f/8, if I differ I&#8217;ll make note of it too.</p>
<p>For city shots with a fair amount of light, you can still meter and be reasonably<br />
    close. If you take into account reciprocity, film sensitivity falls off with more time, you<br />
    should be alright. Reciprocity is tricky, black and white films have a much steeper fall off,<br />
    while slide film is more consistent. You can see these<br />
    <a href="/photo/tools/reciprocity.html">reciprocity tables</a> for a better idea on it.<br />
    Digital has no reciprocity issues, so digital exposures<br />
    at night are usually much shorter than film.</p>
<p></section></p>

<h3>Photography Equipment &#8211; Tripod</h3>
<p>    <img src="/photo/tools/ais/tripod_legs.jpg" border="0" align="right" hspace="5" vspace="5"></p>
<p><b>Tripod </b> &#8212; probably one of the most important pieces of night<br />
    photography is the tripod. You want something solid and sturdy, but light<br />
    and flexible so that you&#8217;ll want to carry it wherever you want to go.
    </p>
<p>I have a three tripods: medium, light and tiny.<br />
    My medium tripod is a Bogen/Manfrotto legs and head: legs are model 3001BN and the<br />
    <a href="http://www.amazon.com/exec/obidos/ASIN/B00009V3D9/mkazcom-20" title="View on Amazon.com">ball head is 3055</a>. I&#8217;m perfectly content with the head and would recommend it.<br />
    The tripod legs I would recommend an alternate model, <a href="http://www.amazon.com/exec/obidos/ASIN/B00006I52X/mkazcom-20" title="View on Amazon.com"> the Bogen 3021B</a>, that model<br />
    comes with quick release knobs for extending the legs. My tripod legs are screw<br />
    knobs and it takes a little more time to extend.</p>
<p>My light tripod is the <a href="http://www.amazon.com/exec/obidos/ASIN/B001KW6IRQ/mkazcom-20" title="View on Amazon.com">Velbon Ultra Maxi</a>. This one is nice, light,<br />
    packable but is also light weight. The maximum height isn&#8217;t that great and it can only hold my 35mm gear with a small lens.<br />
    A great travel tripod and one to always have around, but not a work horse.</p>
<p>My tiny tripod is one of the table top models, a <a href="http://www.amazon.com/exec/obidos/ASIN/B000274GHE/mkazcom-20" title="View on Amazon.com">Bogen 3007</a>  I hardly ever use it for<br />
    night photography but I always have it in my bag. These little tripods are strong, I&#8217;ve used them with my Hasselblad without problems.</p>
<p>That is just my equipment, people seem to be very particular with their tripod selection;<br />
    quick release system and other options. Here are a few other articles discussing it:</p>
<ul>
<li><a href="http://www.photo.net/equipment/tripods/cheap">Cheap and Compact</a></li>
<li><a href="http://www.bythom.com/support.htm">Serious Support</a></li>
<li><a href="http://www.photo.net/equipment/tripods/davis">Tripods, Heads and Quick Release</a></li>
</ul>
<p></section></p>
<p><section></p>
<h3>Photography Equipment &#8211; Film</h3>
<p><b>Film</b> &#8212; Your choice of film has a lot to do with what results you will<br />
    get in night photography pictures. Tungsten balanced film is very common to use<br />
    in night photography, such as Fuji&#8217;s 64T, which is the primary film I use.</p>
<p><a href="/photo/blog/images/2005_R02_10.jpg"><img src="/photo/blog/thumbs/2005_R02_10.jpg" align="left" border="1" vspace="5" hspace="8"></a></p>
<p>Tungsten balanced films will tend to give you more blue or purplish colors<br />
    which people tend to associate with night photography. Fuji&#8217;s Provia is also<br />
    another popular film for night work. I&#8217;ve used Kodak Porta 400VC, the<br />
    results were more of an orange tint, not quite as pleasant. Again:<br />
    practice, experiment and take good notes. </p>
<p>For black and white film, I&#8217;ve used Kodak Tri-X and Ilford HP5 and FP4 films.<br />
    The Ilford films have slightly better reciprocity, but I wouldn&#8217;t declare<br />
    any of the films to be clearly superior. For reciprocity alone, Kodak&#8217;s T-Max seems to<br />
    be best, but I&#8217;ve always avoided T-Max, I think my early B&#038;W instructor scared me away<br />
    from it.</p>
<p>I plan to experiment more with black and white films and development techniques<br />
    for night photography. I&#8217;ll post my results when complete.</p>
<p>    <br clear="all"><br />
</section></p>
<p><section></p>
<h3>Non-Photography Equipment</h3>
<p><b>Flash Lights</b><br />
You will probably need some form of light just to see depending<br />
how dark it is and where you are shooting; loading film in the dark<br />
always sounds easier than it is. The new little LED key chains are<br />
bright, last a long time and work pretty well.  You may also want to use lights<br />
to brighten elements in the scene; different colored lights can add some fun<br />
effects.</p>
<p>I personally have a few LED key chains, blue and white; I have a big Mag-light<br />
flashlight and a few mini-Mags. If I&#8217;m lucky I remember to bring one of<br />
my flashlights.</p>
<p></p>
<p><b>Timer</b><br />
The simple matter of timing your exposures: you can use anything from counting in your<br />
head, a watch or a friend of mine uses his Palm Pilot. I normally use kitchen timers or<br />
if short enough count in my head. Here&#8217;s two timers that I&#8217;ve tried out:</p>
<ul>
<table>
<tr>
<td align="center"><a href="http://www.amazon.com/exec/obidos/ASIN/B00004S4U7/mkazcom-20" title="View on Amazon.com"><img src="/photo/tools/ais/polder_bad.jpg" border="0"></a></td>
<td> the <a href="http://www.amazon.com/exec/obidos/ASIN/B00004S4U7/mkazcom-20" title="View on Amazon.com">Polder 898-90</a> is a very loud timer; I do <b>not</b> recommend this one,<br />
            it ruins the serenity of night and alerts people to your presence; though it is easier to program longer exposures.
        </td>
</tr>

<td> I recommend the <a href="http://www.amazon.com/exec/obidos/ASIN/B0002EXVIM/mkazcom-20" title="View on Amazon.com">Polder 212-00</a>, this one has multiple settings<br />
            to turn off sound, vibrate mode and even a visible light alarm.
        </td>

<h3>Overview</h3>
<p>Here&#8217;s a rough chart to give a starting point for estimating moonlight photography exposures.<br />
Note, this is taking a photo of an subject illuminated by moonlight and not a photo of the moon itself.<br />
I welcome your comments, experience or tips on improving this information.</p>
<div class="note">If you wish to <b>photograph the moon itself</b>, the exposure is much different.<br />
The moon is an object reflected in sunlight, so the rule-of-thumb is to use the &#8220;Sunny-16 Rule&#8221;.<br />
This says, for an object in direct sunlight expose at f/16 and time is 1/ISO.  So for 100 speed film,<br />
your exposure would be 1/125. </div>
<p><b>Remember: </b> experience, practice, patience and bracketing will help all shots. Take good notes.</p>

<h3>Subject in Moonlight &#8211; Static Chart</h3>
<p>The following exposures are for <b>f/8</b> using <b>ISO-100</b> slide film.<br />
See the dynamic form below for different aperture and film settings.  The exposure<br />
times are rough starting points, the subject surface (reflection), ambient light and<br />
other factors will effect your exposure. When in doubt, bracket.</p>
<p></p>
<div style="margin: 0px 25px 25px 25px">

<p>Note: The moon phases are reflexive, so 3 days after a full moon is the same<br />
as 3 days before a full moon.</p>
</div>
<p></section></p>
<p><section></p>
<h3>Sources for Full Moon exposure: </h3>
<div style="float: right; margin: 10px 10px 10px 25px; text-align: center">
    <img src="/photo/tools/ais/moonlight.jpg" border="1" width="240" height="239" alt="Moonlight Reflected"><br />
    <font size="2"><i>Moonlight Reflected on Pacific </i>  <br />
    Full Moon. f/8, 4 mins, Fuji 64t</font>
</div>
<p>Kodak Recommendation from <i>Trial Exposures Under Difficult Lighting Conditions</i></p>
<div style="margin-left: 25px">
    Moonlit landscapes:   30 seconds at f/2 at 100 <br />
    For scenes lit by the unobscured full moon to show full detail in the surroundings, not including the moon in the picture.
</div>
<p><b>Adjusted:</b> ISO 100 film at f/8 is 8 minutes</p>
<p></p>
<p>Another rule of thumb is the <b>Looney 16 Rule</b>, which says the full moon is roughly 250,000 times dimmer than the sun, which works out to 18 stops less light than full sunlight. (2^18 = 262,144) The sunny-16 rule for full sunlight says for ISO 100 film, expose f/16 at 1/125, so adjust this 18-stops.</p>
<p><b>Adjusted:</b> ISO 100 film at f/8 is 8 min 30 seconds</p>
<p>So I used the base exposure for ISO 100 film at f/8 as 8 minutes, since 30 seconds of 8 mins is only a difference of 6% which is a small difference overall. </p>
<p></section></p>
<p><section></p>
<h3>Calculating Luminance for non-Full Moon </h3>
<p>Keep in mind that the days right around the full moon is brightest and then it falls off very quickly. [<a href="http://home.earthlink.net/~kitathome/LunarLight/moonlight_gallery/technique/moonbright.htm">See the Chart: Earth Surface Lunar Illumination</a>]  Also published on the LunarLight site, is the following table which shows the calculated LV values for the above stated moon phases.</p>
<table cellspacing="0" class="mktable">
<tr class="hdr">
<th>Adj Stops</th>
<th>LV</th>
<th>Situation</th>
</tr>
<tr>
<td>13.5</td>

<p></section></p>
<p><section></p>
<h3>Reciprocity Failure</h3>
<p>Reciprocity Failure is a problem that occurs with film&#8217;s ability to evenly measure light during long exposures. The characteristics of film is that during an exposure it is initially very sensitive to light but as exposure time increases the film&#8217;s ability to record light is diminished.  So what a light meter may tell you should be a 1-minute exposure, for a particular film that exposure may actually need to be 8-minutes. </p>
<p>Black and White films are effective more by the reciprocity failure than color or slide film. Check your film data sheet for it&#8217;s characteristics and tables. Data sheets uses were collected from numerous sources (see below). </p>
<p> Unfortunately not all sources publish the same data, most sources have incomplete data for films and even manufacturer data seems suspect especially for very long exposures. All the best efforts were put in to give reasonable values.</p>
<p>Here are the <a href="/photo/tools/reciprocity.html">Reciprocity Tables</a> used for the calculations. Linear interpolation used for in between values. Please let me know if you have corrections, suggestions or more data available. </p>
<p></section></p>
<p><section></p>
<h3>Addendum: Stop Calculations Explained</h3>
<div class="clearfloat">
<div style="float:left; width:500px">
<p>A stop is a doubling of light. So opening an aperture up by making it wider by one stop will half the amount of exposure necessary.  So for example if you needed a 4-minute exposure at f/8, you would only need a 2-minute exposure at f/5.6.</p>
<p>Here is a sample table of different exposure and aperture times, all of these have an equivalent luminance. Starting with a exposure f/8 at 1-minute, look at the range of exposure times based on changing the aperture value. </p>
