People, pets and objects are picked out automatically the moment a photo opens, so most splashes are done before you touch the screen.
Turn it on and your brush stops at edges in the photo, so colour stays inside the lines without zooming right in.
Mono, Noir, Sepia, Faded, Focus, Sketch, X-Ray, Midnight and Neon for everything outside the splash.
Editing happens entirely on the device. Projects are kept so you can come back to them, and finished photos save straight to your gallery.
