The iPhone’s wide-angle lens is very easy to use, especially when taking selfies. You can easily take pictures of the whole family with one hand. But the problem came. The portrait near the edge was severely deformed, and the face was stretched to the point that no one wanted to recognize himself. In order to effectively solve the problem of portrait deformation due to wide-angle lens stretching, this free App was developed. Although there are unpopular advertisements, future upgrades will add in-app purchases to remove advertisements. Please select a photo with a wide-angle effect. If there is no wide-angle effect originally, it will cause distortion. The purpose of this App is to correct the deformation of portraits. As for taking photos of buildings or some hardware facilities, landscape photos, etc., the effect is not significant.
