A profile photo from a picture you already have
A clear phone photo becomes a gray-backdrop portrait that still looks like the same person in the small LinkedIn circle.
The situation
The photo is sharp and the face is visible. The background is a room. LinkedIn will crop the portrait down to a circle, so the face has to stay recognizable when the corners disappear.
What they choose
The LinkedIn look, soft even light, and the clothes already in the photo.
What they get
One portrait, paid once. The face stays. The room does not. It is ready to download for the profile.
