title: Using Preset Filters From CamanJS API
body: <p>I am using CamanJS plugin to apply effects to images, I want to know how do I apply preset effects like lomo, sin city, cross process, etc found <a href="http://camanjs.com/examples/" rel="nofollow">here</a>. The documentation of CamanJS does not  elaborate on this properly.  </p>
  
  <p>I tried the below code to apply vignette effect , but was not successful.</p>
  
  <pre><code>Caman("#effects", function () {
  
          this.resize({width: 650,height: 400
           });
           this.vignette();
          this.render();
  
              });
  </code></pre>
