Magnificent ! ..... I'd be interested to know how you get such movement from what was presumably a photo ?....
Its from a video clip she posted on her Insta. I took a small segment of the video, duplicated it so there were two of them in the same timeline, and then reversersed the second one. What you see is the video going forward to halfway of the gif, and then going backwards until the end of the gif. It forms a relatively smooth infinite loop.
I have seen Ytube videos where long gone people in old photographs have been made to smile and turn their heads. Maybe its possible to take images of breast models, and make it look like they are turning to show their impressive figures. However I have not looked into how to do it.
