Home/ PS Tutorials/ One-Click Cutout and Background Replacement

Quick Selection plus Select and Mask is the least fussy cutout combo there is. Four moves: duplicate the background, select the subject, fix the edge, swap the background — with cutout tips at the end. A beginner can pick this up in ten minutes.

1

Open the image and duplicate the Background layer

  1. Open the image you want to cut out in Photoshop (shortcut Ctrl+O), or just drag the file into the workspace.
  2. In the Layers panel, right-click the Background layer and choose Duplicate Layer (Ctrl+J) to make a copy. Do everything on the copy and keep the original, so you can always go back.
  3. If you use an online PS such as www.zaixianps.cc, layer duplication works there too — right-click the layer thumbnail to find it.
  4. Name the copy something like "Cutout" so you can spot it at a glance.

Select the subject in one click

  1. Select the Object Selection tool in the toolbar (W, usually grouped with the Magic Wand and Quick Selection).
  2. In the options bar set the mode to Rectangle or Lasso and tick Object Finder (on by default in recent versions).
  3. Drag a rectangle over the subject and release; Photoshop recognises and selects it, and marching ants appear around the edge. This is the "one click" at the heart of the whole workflow.
  4. If the selection is off, hold Shift and drag to add, or hold Alt and drag to subtract.
  5. For transparent backgrounds or images with strong color contrast, you can also try the Quick Selection tool and simply paint over the subject to build the selection.

Refine the edge: Select and Mask

A one-click selection saves time, but around hair, fur and other fine edges it often keeps some background color. Select and Mask lets you refine the edge so the cutout looks natural.

  1. With a selection active, click Select and Mask in the options bar (or right-click the selection and choose it).
  2. In the dialog, pick the Refine Edge Brush tool (R) from the toolbar on the left and paint along the edges you need to refine — hair, clothing. The brush separates foreground from background and removes the background color.
  3. On the right, fine-tune Smooth, Feather, Contrast and Shift Edge. For complex images, turn on Smart Radius and raise the radius.
  4. Under Output Settings, choose "Output To: New Layer with Layer Mask" and click OK. The Layers panel now holds a masked copy and the background is transparent.

Put in a new background

  1. Drag the new background image into the document (or use File > Place Embedded) — it lands as a new layer. Move it below the cutout layer.
  2. If the size or position is wrong, select the background layer and press Ctrl+T for Free Transform, then adjust scale and angle.
  3. To make the composite believable, check the light direction, color temperature and shadows of foreground and background. If needed, add Hue/Saturation or Curves adjustment layers and clip them to the subject.
  4. When you're done, press Ctrl+Shift+S and save as PNG or PSD to keep the transparency for later edits.

Cutout tips

  • If the background is a solid color, click it with the Magic Wand tool and invert (Ctrl+Shift+I) to get the subject selection — much faster.
  • In Select and Mask, turn on Show Edge and switch to the "On Black" or "On White" view to see edge leftovers clearly and fix them precisely.
  • Without Photoshop, open the online version at www.zaixianps.cc. It supports object selection and mask editing, and needs no installation.
  • Once the cutout is done, add a little Inner Shadow or Drop Shadow to the subject layer to seat it in the new background.
  • When you save the working file, keep the layers and masks intact so you can revise or swap the background later.

Note: "One-click cutout" is not magic. Transparent objects (glass, splashing water) or extremely fine hair still need patient manual work. But the workflow above handles most everyday cases and saves a lot of time. Once you're comfortable, the whole thing takes a few minutes. Hopefully this tutorial helps you get fast, reliable cutouts and background swaps.
