If you own the Olloclip 3-in-1 lens, then you will be well aware of the optical distortion the lens suffers. Well until now, this optical distortion has been something all Olloclip owners/users have had to put up with (or correct on a PC), but with the aid of new iOS app OlloCorrect, this distortion can be corrected right on your iOS device.
Free and easy to use, OlloCorrect lets you take or load a photo from the camera roll. Then from the simple interface, you simply tell the app if the image was captured with the macro, fisheye or wide-angle lens. Then all that's left to do, is tap the distortion correction button and OlloCorrect begins the auto correction process. When complete, simply save at full-res, or bin the image and start again.
As you can see from the before and after images below, OlloCorrect does an excellent job, and all for free. Despite the cropping (which the app has to do), this is a must have app for all Olloclip lens owners.
