Image-distortion correction (remove the tick in front of "keep vertical and horizontal synchronization correction")-The smaller the vertical line correction value, the thinner the compressed person will be (but not too small, because it will be deformed unlike a person). However, this method can only be used when the person in the photo is artificially upright, otherwise it will be deformed and distorted badly. If you just need face-lifting, it is recommended to use another software "Niuxiang" to directly help face-lifting lose weight.
