The social filter war is officially on: Twitter adds free photo filters to Android and iPhone apps

We knew good and well it was coming, and come it has: Twitter has begun its all-out assault on Instagram (and in turn, Facebook) by including its own set of (free) photo filters. As of now, just the Android version has been updated with the new lenses, but we're expecting iOS and the rest to follow suit in short order. Much like Flickr did earlier this year, Twitter has tapped Aviary to power all of the company's filters and effects.

As of now, users will find just eight filters -- ranging from "black and white to vintage" -- while the grid view enables you to preview how your image would look if any of the eight were applied. You'll also be able to crop, as well as pinch to zoom in order to focus attention. Moreover, there's an "auto-enhance" feature that'll add a little whiz-bang to whatever you managed to snap, and if you're still struggling to wrap your brain around it, there's an introductory video waiting just after break. (As well as a (NSFW) video that speaks the truth about all of these filters.)
