title: How do I convert EXR to PNG and adjust brightness at the same time
body: <p>I was able to convert my EXR image to a PNG using the techniques outlined in <a href="https://stackoverflow.com/questions/28110353/image-conversion-from-iff-and-exr-formats-to-jpeg-format">Image conversion from IFF and EXR formats to JPEG format</a> . </p>
  
  <pre><code>convert 0007.exr /tmp/0007.png
  </code></pre>
  
  <p>Unfortunately the PNG looks quite dim.</p>
  
  <p>What should I add to the imagemagick <code>convert</code> command line to increase the brightness?</p>
