Image Blender is one of the most popular apps for iPhone photography and we have published several tutorials to help you get the most from it. If you have missed those, go here. Today the developer has updated this app and changed a few settings around inside the app as well as fixing a few crashes when undoing in masking mode. It also now requires iOS 5.
This is a free update, if you have previously downloaded this app, if not, you can download it here. It retails for $4.99/£2.99.
