How to Create a Double Exposure in Photoshop

How to Create a Double Exposure in Photoshop

Traditional double exposure combines two film photos by not winding the film between shots, but Photoshop offers far more control over how those two images actually blend together. This tutorial combines a portrait and a photo of flowers using blending modes, Levels, and layer masks, cutting the subject out, rebuilding lost detail with duplicated layers, and finishing with a colored background and vignette.

Combining Two Images Onto One Canvas

Bringing two separate photos together onto one document, with extra canvas room to work in, is the starting point before any blending decisions get made.

1. Drag One Image Into the Other

   Use the Move tool, hold Shift, and click and drag from one image document into the other so both land on the same canvas.

2. Expand the Canvas With the Crop Tool

   Select the background layer, use the Crop tool to drag the canvas larger, and leave Delete Cropped Pixels unchecked so nothing is lost permanently.

3. Position and Scale Each Layer

   Press Cmd/Ctrl+T on each layer to roughly position and scale the subject and the flowers before deciding on any blending, planning where they’ll visually interact.

Choosing High-Contrast Images and a Blending Mode

A double exposure works best with images that are either dark on light or light on dark, since that contrast is what a blending mode like Lighten actually uses to combine them.

4. Add a White Solid Color Layer Beneath Both Images

   Add a Solid Color adjustment layer set to white and place it at the very bottom of the layer stack.

5. Set the Subject’s Blend Mode to Lighten

   Change the subject layer’s blend mode from Normal to Lighten so the lighter of the two images shows through wherever they overlap.

Why High-Contrast Images Work Best for a Double Exposure

An image with a lot of competing midtones, like a busy backyard full of grass, trees, and a pool, gives a blending mode like Lighten too much to work with and produces a muddled result. A simpler high-contrast pairing, such as a dark tree against a bright sky, gives the blend mode clear separation to work from, which is exactly why both source images here were chosen with a plain, contrasting background.

Adjusting Contrast Between Layers With Levels

A Levels adjustment (Cmd/Ctrl+L) applied to either image can push one lighter or the other darker, changing how much each one stands out once the blend mode is applied.

6. Darken the Flowers With Levels

   Press Cmd/Ctrl+L on the flower layer and drag the middle slider to darken it, making the subject stand out more against it.

7. Lighten the Subject With Levels if Needed

   Press Cmd/Ctrl+L on the subject layer and adjust its levels lighter for the opposite effect, experimenting with both directions.

Cutting Out the Subject and Masking the Background

Cutting the subject out from her original background keeps the composition focused on just her shape, and masking unwanted parts of the flower background trims it down to only what’s needed.

8. Select the Background With the Magic Wand Tool

   Select the Magic Wand tool, lower Tolerance to around 9 or 10, and Shift-click the plain background around the subject to select it.

9. Invert the Selection Into a Layer Mask

   Add a layer mask from the selection, then press Cmd/Ctrl+I to invert it so the subject remains visible instead of the background.

10. Mask Out Unneeded Flower Areas

    Add a layer mask to the flower background, use the Lasso tool to select areas that aren’t needed, and fill those areas with black to hide them.

Why Cut the Subject Out Before Blending

Leaving the subject’s original background in place would compete visually with the flowers once the Lighten blend mode is applied, muddying the composition. Cutting the subject out first means only her actual shape interacts with the flower layer beneath, keeping the double exposure effect clean and focused on the intended interaction between the two images.

Duplicating Flower Layers to Bring Back Facial Detail

Because the subject’s blend mode is Lighten, any darker flower texture placed beneath a masked-in area will show back through, which is a way to reintroduce lost detail exactly where it’s wanted.

11. Duplicate the Flower Layer

    Press Cmd/Ctrl+J to duplicate the flower layer and reposition the copy with the Move tool.

12. Change Its Blend Mode to Darken

    Change the duplicated flower layer’s blend mode from Normal to Darken.

13. Mask It to Black and Paint White Where Detail Is Needed

    Fill the layer mask with black using Shift+Delete, then use a white brush to paint back visibility only where extra flower texture and definition are wanted, such as over part of the face.

Why Duplicate Layers Instead of Editing the Original Mask

Editing the original flower layer’s mask directly would mean it can only ever do one job at a time, either forming the main background or adding extra detail somewhere else. Duplicating the layer and giving the copy its own blend mode and mask means the same flower texture can be reused independently in multiple places, each with its own visibility and effect.

Restoring Detail in the Hat With a Shared Layer Mask

Copying an existing layer mask onto a new duplicate, rather than building one from scratch, quickly targets a very specific area like the subject’s hat with additional flower detail.

14. Duplicate the Flower Layer Again

    Duplicate the flower layer a second time to add flowers specifically into the hat area.

15. Copy the Subject’s Layer Mask

    Hold Option/Alt and drag the layer mask from the subject layer onto the new flower duplicate to copy it instantly.

16. Unlink the Mask and Reposition the Flowers

    Click the chain icon to unlink the layer from its mask, then move and scale the flowers with Cmd/Ctrl+T to fill in the hat area without moving the mask.

17. Group and Mask to Isolate Just the Hat

    Group the layer, add a mask to the group, invert it to black, and paint white only over the hat area where the extra flower detail should show.

Cleaning Up Distractions With the Clone Stamp Tool

A small distracting dark spot, like an unwanted mark near the eye, can be cleaned up with the Clone Stamp tool sampling from the layers below.

18. Set the Clone Stamp to Sample Current and Below

    Select the Clone Stamp tool and set its sample option to Current & Below.

19. Sample and Paint Over the Distraction

    Sample a nearby clean area and paint over the unwanted dark spot to remove it.

Coloring the Background and Adding a Vignette

Once the composite itself is finished, grouping everything and adding color adjustment layers turns the plain white background into something more atmospheric.

20. Group All the Composite Layers

    Select every layer used in the composite and press Cmd/Ctrl+G to group them together.

21. Add a Levels Layer for Background Color

    Add a Levels adjustment layer above the group and adjust the output levels on the Red, Green, and Blue channels to shift the background away from plain white toward a chosen color.

22. Add a Radial Gradient Vignette

    Select the Gradient tool, choose a black foreground-to-transparent radial gradient, and drag it on the Levels layer’s mask, centered on the subject, so the color falls away there and the center stays bright.

Finishing With a Complementary Color Tint and White Border

A colorized Hue/Saturation layer around the edges and a simple white frame give the finished piece a final polished look.

23. Add a Colorized Hue/Saturation Layer

    Add a Hue/Saturation adjustment layer, turn on Colorize, and choose a complementary color to the background.

24. Paint the Color Around the Edges

    Invert the layer mask to black, then use a foreground-to-transparent white gradient to paint the color back in around the edges of the frame.

25. Add a White Border

    Use the Rectangular Marquee tool to select just inside the canvas edge, invert the selection with Shift+Cmd/Ctrl+I, and fill it with white using Shift+Delete for a clean white border.

Why This Approach Works

Choosing two high-contrast images and cutting the subject out from her original background is what gives a blending mode like Lighten clean, clear shapes to combine, instead of a muddled mix of competing tones. Duplicating the flower layer for each area that needs extra detail, rather than trying to make one layer do everything, is what makes it possible to build up a hat full of texture and a face with visible features without any single layer becoming unmanageable. Grouping the entire composite before the final color pass is what allows a background color, vignette, and complementary tint to be added on top without disturbing any of the careful blending work done underneath.

Final Thoughts

What looks like a single complicated effect really breaks down into a handful of simple, repeatable ideas: high-contrast source images, a blending mode like Lighten or Darken, and layer masks used liberally to bring specific detail back exactly where it’s wanted. Once those pieces click, this same approach with a different portrait and a different background element, and a deeper look at our tutorial on mastering blending modes in Photoshop, opens up an entirely different double exposure every time.
