<p>OpenColorIO (OCIO) is a complete color management solution geared towards motion
picture production with an emphasis on visual effects and computer animation.
OCIO provides a straightforward and consistent user experience across all
supporting applications while allowing for sophisticated back-end configuration
options suitable for high-end production usage. OCIO is compatible with the
Academy Color Encoding Specification (ACES) and is LUT-format agnostic,
supporting many popular formats.</p>
<p>OpenColorIO is released as version 1.0 and has been in development since 2003.
OCIO represents the culmination of years of production experience earned on such
films as SpiderMan 2 (2004), Surf’s Up (2007), Cloudy with a Chance of Meatballs
(2009), Alice in Wonderland (2010), and many more. OpenColorIO is natively
supported in commercial applications like Katana, Mari, Silhouette FX, and others
coming soon.</p>
<p>OpenColorIO is <a class="reference external" href="http://opencolorio.org/License.html">free</a> and is one of
several open source projects actively sponsored by <a class="reference external" href="http://opensource.imageworks.com">Sony Imageworks</a>.</p>

<h2>Using OpenColorIO<a class="headerlink" href="#using-opencolorio" title="Permalink to this headline">¶</a></h2>
<p>Most users will likely want to use the OpenColorIO that comes precompiled with
their applications. See the <a class="reference internal" href="CompatibleSoftware.html#compatiblesoftware"><em>Compatible Software</em></a> for further details on
each application.</p>
<p>Note that OCIO configurations aren’t required to do any ‘real’ work, and are
available separately on the <a class="reference internal" href="downloads.html#downloads"><em>Downloads</em></a> section of this site. Example
images are also available. For assistance customizing .ocio configurations,
contact the ocio-users email alias.</p>
<ul class="simple">
<li>Step 1: set the OCIO environment-variable to /path/to/your/profile.ocio</li>
<li>Step 2: Launch supported application.</li>
</ul>
<p>If you are on a platform that is not envvar friendly, most applications also
provide a menu option to select a different OCIO configuration after launch.</p>
<p>Please be sure to select a profile that matches your color workflow (VFX work
typically requires a different profile than animated features). If you need
assistance picking a profile, email ocio-users.</p>
