Now that Prisma has finally been released for Android you probably have a complete portfolio of artwork. Unfortunately the app adds an annoying watermark to all of your images by default. Luckily the creators of Prisma were nice enough to include the option to turn wartermarks off. To turn off watermarks: -Choose Settings Button from the main photo taking screen -Uncheck Add Watermark setting -Press the back key That's it! Easiest fix ever right?!
