There is a relatively new effect that is becoming quite popular lately. It is a way to make still images come alive by separating the subject of the picture from the background and moving them in 3D space. This video contains examples of this effect.
I have been working with still photos in videos for over 20 years. When I started, the only way we could do picture moves was to zoom the camera in on a photo and pan across it. For one project, I spent days in the archives placing photos on an easel and carefully panning right, left, tilt down, zoom out… it was tedious work.
Since those days, software has allowed us to do these effects digitally. For the 3D picture move, you often need to replace the background after you cut out the subject. That is usually the trickiest part because you are creating a background that is not part of the photo. But advances in photo editing software have made that much easier. So I’m certain we will see more of this effect. And just like panning and zooming on a photo added visual interest, using these effects can make the video much more dynamic than it would be with the original still image.
