<h1>EPPM Files</h1>
<p>EPPM is an extension to the PPM file format that allows specification of
metadata. The header of an EPPM file conforms to the following template:
<pre>
P6#E
# Tag1: Value
# Tag2: Value
# Tag3: Value
# .
# .
# .
Width Height Maxval
Data
</pre>
<p>Tags recognized by ALE are outlined below.
<h2>Black level</h2>
<P>The black level tag specifies a value that should be subtracted from
all pixels in order to achieve linearity. A modified version of dcraw (<a
href="/darcs/dcraw">darcs repository</a>) can be used to generate files
containing this tag.
<pre>
# Black-level: &lt;value&gt;
</pre>
<h2>Exposure tags</h2>
<p>Exposure tags can be used for determining tonal registration through
specification of shutter speed, aperture, and ISO sensitivity (or gain).
<pre>
# Shutter: &lt;value&gt;
# Shutter: 1/&lt;value&gt;
# Aperture: &lt;f-number&gt;
# ISO: &lt;value&gt;
# Gain: &lt;value&gt;
</pre>
