Not directly. Photoshop works with existing image files; it doesn’t provide a true live camera feed or automatically place each new tethered capture into a Photoshop layer for live compositing.

A practical workaround is to use your camera’s tether/capture software separately and view it alongside your background image. One community suggestion was using a transparent-window utility on Windows so your capture software can sit over the background image for rough alignment and lighting preview.

For the actual composite, shoot on a backdrop that’s easy to mask cleanly. A green screen is commonly used for this kind of work and is often easier to key than white for many subjects. Once the images are in Photoshop, place them on separate layers, mask the subject, and use color/temperature adjustments to better match the studio shot to the background.

So: Photoshop alone won’t do a live layered preview from the camera, but tethering software plus a display workaround can get you close.
