Step 13 Add a new layer to the top of the layer stack and fill it with blue (#12497c). Change the opacity to 60% and the blend mode to Soft Light. Add another layer and fill it with green (#257940). Change its opacity to 60% and the blending mode to Soft Light.
Step 14 We want to add a simple vignette effect. Add a layer on top. Fill it with black. Change the blending mode to Multiply. Select the Brush tool (B) and a very big soft brush, with white for the colour. Paint over the girl’s face and other areas, leaving just the edges.
Step 15 To add a glow effect, first select all the layers, and right click > Duplicate Layers. With the duplicated layers still selected, go to Layer > Merge Layers (Cmd/Ctrl + Alt + Shift + E). Next, go to Filter > Blur > Gaussian Blur. Use 20 pixels for the Radius. Change the blending mode to Screen and reduce the Opacity to 80%.
