The filters available in Instragram and other retro camera apps can be impressive, but it's annoying when every photo is flush with unnatural colour. If you want to reclaim a photo that has been unnecessarily filtered with effects, Normalize will fix it for you in just a few taps.
Normalize works by accessing photos in your clipboard or photo library. You just paste one in or select it from any album and it will fade any filters automatically. From there you can pinch in with two fingers to see the difference, or you can tap the edit button to adjust the de-filtering process. When you're done editing, just save the image back to your camera roll. That's pretty much all there is to Normalize. It's simple, straightforward, and costs $0.99 for a hybrid app that works on all your iDevices.
