Live Effects Enabler adds Live Filters to Camera application in iOS 7 for iPad and iPhone 4
Apple added in iOS 7 live filters that allow users not only to achieve pictures with them, but also to see some of the most awesome effects in real time. This option is available only on newer iPhones like from iPhone 4S and iPod Touch 5th generation above.
Apple notes on its own website:
Filters in Camera are available on the iPhone 4s or later and iPod touch (5th generation 32GB/64GB).
Recently, there was launched a tweak in Cydia called Live Effects Enabler which also promises to introduce this feature on unsupported devices capable of running iOS 7. These include Air iPad, iPad Mini Retina, iPad 4, 3, 2, and the first iPad Mini, and of course iPhone 4.
Live filters are enabled native and works exactly like the on device with the option enabled by Apple. In the native Camera app from iOS 7, there is added a button that provides access to the 9 filters.
Although Apple has decided not to add this feature on all devices, it does not cause any lag or issues of Camera application.
Live Effects Enabler is available in the BigBoss repo from Cydia.
