Larson’s first step is hiding the plain gray wall. Use the Quick Selection tool to select just the shape of the model. Choose Select Subject and then choose Select And Mask to enter the Select And Mask workspace.
Step 2: Remove rough spots
In the Properties panel of the Select And Mask workspace, move the Shift Edge slider to the left to refine the edges of the selection, and choose Output To Selection. Note: when leaving Select And Mask, the original background comes back; you’ll fix this in the next step.
Step 3: Delete the wall
With the model layer selected, click on the Add Layer Mask icon. Since Larson had output the model as a selection from the Select And Mask workspace, Photoshop masked (or hid) anything that was not selected so the gray wall disappeared and the selected model remained.
Step 4: Create a consistent look
Larson wanted to match the lighting of the model with that of the background. To do this, duplicate the New Background layer, move it above the model layer, and choose Filter > Blur > Average. Option-click (or alt-click) between the green layer and the model layer to create a clipping mask.
Step 5: Add a new background
With the green layer selected, set the Blend Mode to Soft Light, and reduce the Opacity setting. Larson applied a dark blue Solid Color adjustment layer to give each of the layers below it a finishing color cast. Set the Blend Mode to Soft Light and also reduce the adjustment layer’s Opacity setting.
