Editing it all Together / Piece together your spooky portrait
1 Get your images
Download some free stock fire images from www.pexels.com. Go to Photoshop and click on File>scripts>load files into stack then click on Model.jpeg and Skull. jpeg. Click OK and your pictures will open into a single document.
2 Cut out the skull
Ensure the skull layer is at the top. Select the Magic Wand tool (W) and click on the black section, then click the Add Vector Mask button, then Cmd/ Ctrl+i to invert it and reveal the skull. Repeat for the model layer.
3 Place the fire
Next, navigate to your downloaded fire images and drag them into your Photoshop document. Place the background fire image at the bottom of the Layers palette and the fire for the skull at the top of the palette.
4 Flame the skull
Reduce the layer opacity of the fire for the skull and resize it to fit the skull shape. Then change blending mode to Screen and return opacity to 100%. Add a Levels adjustment layer and darken the Blacks to blend it in.
5 Add some glow
Add a new layer above the skull layer. Sample the flame with the eyedropper tool, select the Brush tool (B) and paint the skull and the right-side of the model, turn Blending mode to Color, and lower the opacity to 50%.
