Step by step for an arty abstract
Use Photoshop’s screen blending mode to recreate a double-exposure effect
01 prepare your base
Open your portrait shot in Photoshop and go to Image> adjustments> levels to increase the brightness and contrast. You might also want to use the Clone tool to remove any distracting elements around the face or in the background. You could add an Adjustment layer and tweak the Levels instead.
02 import second image
Open your fill image in Photoshop. Landscapes, or scenes with interesting shapes or textures, such as leaves and flowers, work well. Go to Select> all and then Copy it. Open your portrait shot and paste one image on top of the other. Go to Edit> transform if you need to Rotate, Scale or Flip your fill image.
03 blend and adjust
Next, click to select your striking nature shot and change the blending mode to Screen. Your blended exposure will now have appeared, but we’re not quite finished yet. Try using the Move tool to reposition your fill layer over the portrait. Pay attention to what covers the features – you don’t want any twigs in eyes!
04 final edits
The last step is to make the image less wishy-washy. Add a Curves adjustment layer to bring out detail in the midtones, and use the Burn tool to selectively darken areas of the face. Desaturate the face layer for a more subtle mono result. You could even play around with erasing the bottom of your portrait.
