Double exposure — blending two images into one so they read as a single, layered scene — looks complex, but it's really just blending modes and masks, covered in earlier guides, applied together toward a creative result. Here's a full walkthrough.
What You're Actually Trying to Create
A classic double exposure combines a portrait silhouette with a second image — often a landscape, texture, or cityscape — visible only within the shape of the person. The effect works because the two images share overlapping tonal areas, not because of any single "magic" tool.
Step 1: Prepare Your Subject
Start with a portrait, ideally shot against a plain background for an easier selection. Using the Quick Selection tool (covered in the selection tools guide), select your subject and turn that selection into a layer mask. At this stage, you just need a clean silhouette — the internal detail will be replaced by the second image.
Step 2: Convert the Subject to Black and White
Add a Black & White adjustment layer, clipped to your subject layer (right-click > Create Clipping Mask, from the advanced masking guide). Double exposures typically work best in black and white or a limited color palette, since it keeps the blended result from turning muddy once two full-color images overlap.
Step 3: Bring In Your Second Image
Place your second image (a forest, a city skyline, a texture) directly above your subject layer. Resize and position it so the most interesting part lines up with your subject's head or torso — this is where the eye will naturally focus.
Step 4: Clip It Into the Subject's Shape
Right-click the second image's layer and choose Create Clipping Mask, using your subject layer as the base. The second image now only shows up within your subject's silhouette.

Step 5: Blend the Two Together
This is where blending modes (from the blending modes guide) do the real work. Try Screen first — it tends to work well here because it keeps the second image visible while letting the darker parts of your original subject show through as shadow. Lighten is a good second option to compare against.
Adjust the second layer's opacity if the effect feels too strong — often somewhere between 70-90% opacity reads more naturally than 100%.
Step 6: Refine With a Layer Mask
Add a regular layer mask on top of the clipped, blended image and paint with black at low opacity to fade out areas where the effect looks too busy or distracting — commonly around the eyes or face, where too much texture can make the result look cluttered rather than intentional. Keeping the face slightly cleaner than the rest of the silhouette usually makes the final image easier to read.
Step 7: Tie It Together With a Final Adjustment
Add a Levels or Curves adjustment layer above everything (not clipped, so it affects the whole composite) to unify the contrast across both images. This step matters more than people expect — without it, the two source images often look like they're visibly from different photos rather than one cohesive piece.

Common Mistakes to Avoid
- Skipping black and white conversion — full-color double exposures usually look muddy rather than intentional
- Using two busy images — if both the subject and the second image are highly detailed, the result often reads as visual noise rather than a clean effect
- Ignoring composition — the second image's most interesting part should land somewhere meaningful on your subject (the head, a hand), not randomly across the frame
A Good First Practice Combination
A simple portrait silhouette combined with a forest or tree-line image is one of the most forgiving combinations to start with — the natural texture and tonal range of trees blends well with skin and hair silhouettes, and mistakes are less obvious than with a busy cityscape.
