Add someone into a group shot or a scene they missed. Describe who should appear and where they stand, and they are composited in at the right scale with matching light and a proper contact shadow.
How the add a person to a photo works
Upload the base photo and describe the person and their position, for example 'add a man in a navy jumper standing to the right of the woman, same height'. Mention their pose and where the light falls. Run the tool and check the ground contact, the shadow direction and the scale relative to the others. Refine the wording and run again on the same upload until they sit naturally.
Tips for the best results
Give height relative to someone already in frame, since scale is what breaks a composite first. Name the light direction so the shadow lands correctly. Ask for a soft contact shadow where their feet meet the ground. Only add people who have agreed to it, and never a public figure.
