Replacing a background in Adobe Photoshop can be done using several methods. Here’s a step-by-step guide to help you get started:

  1. Open Your Images:

    • Open the image you want to edit and the new background image in Photoshop.
  2. Select the Subject:

    • Use the Quick Selection Tool or Select Subject button to select the main subject of your image. This tool uses AI to automatically detect and select the subject.
  3. Refine the Selection:

    • Go to Select and Mask to refine the edges of your selection. Use the Refine Edge Brush Tool to improve the selection around hair or other fine details.
  4. Create a Mask:

    • Once you’re satisfied with the selection, click OK to create a mask. This will isolate your subject from the background.
  5. Place the New Background:

    • Drag the new background image into your project and place it below the layer with your subject in the Layers panel.
  6. Adjust and Blend:

    • Use the Transform Tool (Ctrl+T or Command+T) to resize and position the new background.
    • Adjust the colors and lighting to match the subject and background using adjustment layers like Levels, Curves, or Color Balance.
  7. Fine-Tune the Mask:

    • If needed, refine the mask further by painting with black or white on the mask to hide or reveal parts of the subject.
  8. Export Your Image:

    • Once you’re happy with the result, go to File > Export > Export As to save your edited image.
