Basic Photoshop / Lesson 6: How to Change a Photo’s Background

This lesson cleanly replaces a photo’s background — useful for CV headshots, product shots, social covers, anything.

2026 note: Recorded on Photoshop CS6 in 2014. Adobe sells Photoshop via Creative Cloud subscription now; about 95% of the menus and shortcuts in the video still match the modern version.

Steps (Classic Method)

  1. Duplicate the background layer.
  2. Select the subject: rough out with Quick Selection (W), refine via Select and MaskRefine Hair.
  3. Output To: Layer Mask, OK. Subject lands masked on its own layer.
  4. Drop the new background underneath.
  5. Color spill on the subject’s edges? Apply Layer > Matting > Decontaminate Colors.
  6. Add a touch of Gaussian Blur (3-8 px) to the new background — mimics camera depth of field.
  7. Match subject color to the new background: Match Color or a small WB tweak in Camera Raw.

2026 Shortcuts

  • Select Subject + Generate Background: Photoshop CC 2024+ auto-cuts the subject and lets Adobe Firefly generate a new background from a prompt.
  • remove.bg and similar web services strip the background in one click.
  • On iPhone, long-press the subject in the Photos app and pick “Copy Subject” — paste into Photoshop.

Pro Tip

Make sure the light direction on the new background matches the subject. Side-lit portrait + front-lit background gives the trick away instantly.
