Afterlight for iOS photo editing is a very popular app, it offers a simple UI with fast processing and a host of filters, textures and adjustment tools. It’s just got a little bit better though, this new update now includes Fusion Filters, essentially allowing you to create your own unique filters in your own personal style.
This update is free, if you have previously downloaded this app. If not, you can pick it up here. It retails for $0.99/£0.69.
