Negative for iPhone by Kyle Hankinson is now free in the App Store, down from $1.99. The app converts any image, either taken within the app or imported from your photo library, and converts it to a negative. Negative saves images in full-resolution and supports iPhone 5MP file sizes.

That’s all Negative does. The conversion is automatic and there are no settings or adjustments. Several other apps have a Negative effect as part of their features, so if you have one, this merely duplicates that functionality.

If you don’t have an app with a Negative filter, this one is fast, easy and for now it’s also free. Freebies like this often go away quickly, so if you’re interested, grab it now.
