How do I remove moving people or cars from multiple identical shots to leave only the background?

I have a series of photos of the same scene, shot from the same position and framing, while people or other objects move through the frame. I want to combine the images so that only the static background remains, creating an "empty" street or similar scene. What is the usual way to do this, and are there any alternatives in-camera?

you have two choices

the first method use software (photoshop)

  1. shoot from the same angle using your tripod (preferable) - time laps shoots. or
  2. shoot when you can see the street is clearer as much as possible some shoots.
  3. now combine all your shoots in photoshop using Auto-align and median tool.

The second method is to use your camera with a long exposure using your tripod and a suitable ND filter depending on how long you expose and the light intensity of your scene. some do it using a square glass holder with a dark glass.

Yes—this is commonly done by combining multiple shots taken from a fixed camera position.

The usual method is:

  • Put the camera on a tripod.
  • Shoot several frames of the same scene with identical framing.
  • In software, align the images if needed, then blend them using a median/average-style stack so moving subjects are rejected and the static background remains.

Photoshop can do this with auto-align plus a median stack, and simpler free tools such as StarStaX can also average images for this kind of effect.

An in-camera alternative is a long exposure from a tripod. If people or vehicles keep moving and never stay in one spot for long, they can blur away or disappear. In bright light, you may need an ND filter to make the exposure long enough.

Best results come from:

  • a locked-down tripod
  • no camera movement between frames
  • as many clean frames as practical
  • avoiding cases where a person stays still in the same spot across many images
