Step 6 The previous step gives you a sepia tone. Adjustment layers always have a layer mask active, so with the Brush tool (B) and a very soft black brush, start painting the area over the model’s face and the soap bubble to let the previous layer show through. These areas will be in full colour while the rest of the image retains the sepia tone.

Step 7 Select all the layers and duplicate them (Layer > Duplicate Layers), then do Layer > Merge Layers or Cmd/Ctrl + Shift + Alt + E to merge the duplicated layers into one.

With this new layer selected, go to Image > Adjustments > Desaturate, then do Filter > Blur > Gaussian Blur with a radius of 20 pixels. After that, change the layer’s blending mode to Soft Light, with the opacity at 100%.

Step 8 Once again, duplicate and merge all the layers prior to step 7. Go again to Filter > Blur > Gaussian Blur with 20 pixels for the radius again.

Set the blending mode of this new layer to Screen and then, with the Eraser Tool (E), delete the areas over the model’s face and hands and the soap bubble.
