title: Instagram like photo editing feature
body: <p>I have seen apps like <code>Instagram</code> and many more, could take a photo and change the colour of the image, as in fade, brightness, gray-scale, and various image processing effects added to it.</p>
  
  <p>I need to try this out, so can someone help me find a good tutorial, to begin with.</p>
  
  <p>For now, my program could take the picture from the camera, but I am unable to process the image as shown on Instagram.</p>
