iOS: Flickr just scored an impressive update on iOS. You can now create custom filters and use Photoshop-grade editing tools and shooting grids.
When you update, you'll find a whole bunch of new filters. If that doesn't satisfy you, however, Flickr now allows you to create your own and preview them live as you shoot.
If you'd rather go the more traditional route, the app also added a variety of camera tools for easy editing. Photoshop users will recognise a few of them: levels, white balance, colour balance and sharpen. If you need a little guidance when composing a photo, new shooting grids can help you out.
As always, you can grab the latest Flickr update for free on the iTunes App Store.
