title: iOS/Xcode: Creating Photo Filters
body: <p>I am currently exploring ways to create a handful of photo filters for my client. Has anyone else ever worked on creating and implementing filters in Xcode before? How did you go about it and are there any best practices?</p>
  
  <p>What did you use to create the filters? Did you manipulate photos directly through Xcode or did you use Photoshop or similar to begin with?</p>
  
  <p>Alternatively, is there a good set of out-of-the-box filters one could use as a base? </p>
  
  <p>Curious to hear your process.</p>
