title: How to create Lomo / Retro effects in Android Camera Preview?
body: <p>Since Android 2.0 onwards, the camera API has supports few ColorEffect(s).</p>
  
  <p>The list could be found here, from Effect Aqua onwards.
  <a href="http://developer.android.com/reference/android/hardware/Camera.Parameters.html#EFFECT_AQUA" rel="noreferrer">http://developer.android.com/reference/android/hardware/Camera.Parameters.html#EFFECT_AQUA</a> </p>
  
  <p>The effect could be implemented as follows:</p>
  
  <pre><code>Camera.Parameters parameters = camera.getParameters();
  parameters.setColorEffect(Camera.Parameters.EFFECT_AQUA);
  camera.setParameters(parameters);
  </code></pre>
  
  <p>Apart from those supported effects, I am thinking to introduce Lomo or Retro effect in my application. Can anyone give some guidance on how to provide extra effects for the camera preview?</p>
  
  <p>Code samples will be greatly appreciated.</p>
  
  <p>Thanks.</p>
