I seem to spend an inordinate amount of time experimenting with filters on Snapchat. I don't ever actually send any messages on Snapchat. I don't have a clue how it works. But I do know how to capture photos of my face with odd filter effects. It takes less time than Photoshop.
If you don't know me (which applies to just about everyone), you'd think I like my face. On the contrary, I am appalled by it, especially as it ages. I struggle with selfies to try and hide the double chin and sagging flesh. Filters at least hide some of the flaws.
Ironically, I hate having photos taken of myself. Inevitably, I look huge. And photographs always seem to capture me in the most unflattering poses with my mouth have open. Selfies with filters remedy some of that.
They also help me indulge in role playing fantasies. For example I think I would have made a pretty good cowboy.
