title: Instagram Lux effect
body: <p>Instagram added a Lux button recently, which allows auto-contrasting / leveling for the pictures you take. </p>
  
  <p>I have a bunch of pictures that I need to autolevel in a similar manner, making those pics better looking. If I would want to use a batch command with Imagemagick, what would be the "secret ingredients" to use? Should I just stick to the contrast setting, or play around with levels, etc.? </p>
  
  <p>As I do not know if the original picture will be dark, bright, already contrasted, I will need to analyse the pic before processing it. </p>
  
  <p>Therefore 2 questions:</p>
  
  <ol>
  <li><p>What are the settings I should look at in creating my batch command for Imagemagick that will consistently output better looking pics?</p></li>
  <li><p>Does it make sense to run the batch and revert the "false positives" by hand later (I have around 50,000 pics to process)?</p></li>
  </ol>
