I want to make an image like the example linked, where the same person appears multiple times in one scene. What is this technique called, and how would I shoot and edit it in Photoshop CS6? I’m especially interested in what to pay attention to when taking the photos, such as lighting, positioning, and making the final composite look realistic.

When shooting, make sure the lighting is similar for best results. It wouldn't surprise me if the photo of her standing up was taken right before or after the main one in the same place.

Then, it is a matter of removing the background from the photo that you want to nest in. It can be done with some automated techniques if the background is a different color from the subject (using the magic select tool) or can be manually painted out by erasing the background from a layer that it is on.

This new subject only layer can be scaled and positioned over the background plate so that the positioning is correct and then some shadows are either painted in or projected in based on the shape of the layer and a light source direction. Some other minor airbrushing changes might be done to help blend the image together better, but that's the general idea.

This is generally called a photo composite or compositing.

To make it convincing, the most important part is shooting all the source images with matching light: same direction, intensity, and color. It helps if the extra pose is photographed in the same location, right before or after the main shot, so perspective and lighting stay consistent.

In Photoshop, a common approach is:

  1. Use one image as the background/base scene.
  2. Put the other shot on a new layer.
  3. Remove its background, either with a selection tool if the background separates easily from the subject, or by manually masking/erasing.
  4. Scale and position that layer so it fits naturally in the scene.
  5. Add realistic shadows based on the light direction.
  6. Do small retouching or airbrushing adjustments to help the elements blend.

What to focus on while shooting:

  • keep camera position and perspective consistent
  • match lighting as closely as possible
  • think ahead about where the added subject will stand or sit
  • make sure shadows will make sense in the final scene

Realistic shadows and matched lighting are what usually make or break the effect.
