<Picture 1> is the location; keep its layout and furnishings, with all surfaces clear of small objects.

<Subject 1> is the camera in this clip — only his hand and forearm appear in frame, in the sleeve of the outfit in <Picture 3>.
<Subject 2> is the woman with light brown wavy hair in <Picture 5>, wearing the skinny pants, the light blue chambray shirt and the white cotton bralette scattered with small embroidered red cherries in <Picture 6>.

Each person keeps the same face, hair and outfit whenever they appear.
