title: Lomography effect in gdi+
body: <p>I'm looking to implement colour filters to images in a similar way to the effect done in this <a href="http://tutorialpulse.com/56/lomo/" rel="nofollow">tutorial</a> </p>
  
  <p>I don't really get colour matrices as the moment and my maths is quite frankly appalling so it's all a bit above my head.</p>
  
  <p>Does anyone have any example code for how to do the filtering part? I already have code written that will add a vignette effect.</p>
  
  <p>Many thanks in advance.</p>
  
  <p>edit: The code needs to be safe as I want to be able to use it in imagehandlers. Sorry if I wasn't clear enough before.</p>
