run through Waterlogue
I'm playing around with the Waterlogue app tonight. It does a pretty convincing job of turning your photos into watercolours, and it gives you a number of options such as watercolour styles, image sizes, levels of light and dark, and whether or not to have a simple border.
I am going to abuse this. I just know it. If you need someone to blame, this is all
's fault for showing this to me in the first place.
