To create a duotone double exposure effect in Photoshop, you blend two black and white photos of the same subject, then uncheck one RGB channel in the Advanced Blending Options. The two shots separate into a pair of complementary colors, and the whole look comes together in about ten minutes.
This is the effect you see on album covers and movie posters: one figure in red, the second exposure ghosting through in cyan. In this tutorial, we build it with two dancer photos, and every piece of it stays editable.
Key Takeaways
- The duotone comes from the Advanced Blending Options: unchecking the R, G, or B box on the top layer splits the two photos into a complementary color pair.
- Both photos are first converted to black and white. The colors are built by the channels, not by the photos.
- Auto-Align Layers matches the two shots so the backgrounds line up, and a soft-brush layer mask hides any remaining seams.
- A clipped Levels adjustment controls how much of each color shows: darker brings in more of one, brighter brings in more of the other.
- The Hue slider swaps the color pair while keeping them complementary, so you can go from red and cyan to any other complementary pair.

What Is a Double Exposure?
A double exposure comes from film photography. The photographer exposes the same frame of film twice, often at half the normal exposure each time, so two images print into one frame without blowing it out.
Some digital cameras offer a multiple-exposure mode that imitates the trick. Photoshop gives you far more control: you choose the two photos after the fact, decide exactly how they blend, and in this duotone version, you also split them into two complementary colors for a more dramatic, graphic result.
Set Up the Document
The goal of the setup is simple: both photos in one document, backgrounds lined up as closely as possible, so the dancers are the only thing that changes between the two exposures.
Step 1: Place Both Photos in One Document
Open both photos in Photoshop. With the images in two separate tabs, select the Move Tool, then drag one image up onto the other document’s tab. When the tab switches over, release the mouse to drop the photo into that document.
Step 2: Auto-Align the Layers
Hide the top layer by clicking its eye icon and you will notice the two photos are not aligned. Turn it back on, then select both layers by holding Shift and clicking each one.
Go to Edit > Auto-Align Layers, select Auto, and press OK. Photoshop lines the two shots up for you.
Step 3: Mask the Seams
After the alignment, the edges of the canvas may show transparent pixels or visible seams where the two frames disagree.
To hide them, select the top layer and click the Layer Mask button at the bottom of the Layers panel.
Select the Brush Tool, and in the Options bar, open the brush settings drop-down. Set the Hardness to 0 so you paint with a soft edge.
Set the foreground color to black and paint over the seams on the layer mask to hide them.
If you hide too much, press X to swap to white and paint the pixels back in.

Step 4: Make Both Layers Black and White
The duotone colors will come from the channels, not from the photos, so both layers need to lose their color first.
Select each layer, go to Image > Adjustments > Black and White, then click OK. The default conversion is all this effect needs.
Then right-click each layer and choose Convert to Smart Object, so the distortions and filters you apply later stay editable.
PRO TIP: Do the Black and White conversion before converting to Smart Objects. Direct adjustments from the Image menu are unavailable on a Smart Object. If you want the conversion itself to stay editable too, use a Black & White adjustment layer clipped to each layer instead.
Step 5: Uncheck a Channel in the Advanced Blending Options
In the Layers panel, double-click the empty area to the side of the top layer’s name to open the Layer Style window.
In the Advanced Blending section, you will find three small checkboxes labeled R, G, and B. Uncheck the R box.
Unchecking a channel is like switching off one of the three lights that build the image. The top layer stops contributing red, the bottom layer’s red shows through, and the two exposures separate into red and its complementary color, cyan.
Each channel gives you a different complementary pair:
| Channel you uncheck | Color pair you get |
|---|---|
| R (Red) | Red and cyan |
| G (Green) | Green and magenta |
| B (Blue) | Blue and yellow |
If you want the layers to swap colors, check R again and uncheck it on the other layer instead. The same goes for the other channels.
This trick is a close cousin of blending modes. If you want to understand what Photoshop is doing under the hood, read my complete guide to blending modes.
Adjusting the Blend
To control how strongly each exposure shows in the duotone double exposure effect in Photoshop, add a Levels adjustment layer above the top layer.
Clip the Levels adjustment to the layer below it by pressing Ctrl Alt G on Windows or Command Option G on macOS. The clipping mask keeps the adjustment on that one layer instead of the whole stack.
Now drag the Levels sliders and watch the blend change. Making the layer darker brings in more red, and making it brighter brings in more cyan. Set the balance wherever it looks best to you.
Adjusting the Hue and Saturation
The red and cyan pairing is only the starting poinred-and-cyan/Saturation adjustment layer at the top of the stack.
Drag the Hue slider, and both colors rotate together around the color wheel. Because the effect is based on a channel split, the two colors always remain complementary. You can land on orange and blue, purple and green, or any other pair of opposites.
Push the Saturation slider up to make the pair richer, and use the drop-down above the sliders to target one color range without moving the other.
Combine the Layers and Finish in Camera Raw
Once you are happy with the colors, select the top layer, hold Shift, and click the bottom layer to select the whole stack. Then right-click and choose Convert to Smart Object. Everything collapses into one Smart Object you can treat as a single image, with all the layers still intact inside it.
Go to Filter > Camera Raw Filter for the finishing pass. Use the tone and color sliders to add the final contrast and mood, then press OK.
Because the filter is applied to a Smart Object, it remains editable. Double-click the Camera Raw Filter entry under the layer any time to change the finish.

Frequently Asked Questions
Two photos of the same subject blended into a single frame and rendered in complementary colors instead of full color. You build it by making both layers black and white and unchecking one RGB channel in the Advanced Blending Options.
The closer the backgrounds, the cleaner the blend. Shoot both frames from the same spot if you can, let Auto-Align Layers line them up, and hide the remaining seams with a soft brush on a layer mask.
The duotone colors come from the RGB channels, not from the photos. If the photos retain their original color, they mix with the channel split and muddy the two-color look.
It stops that layer from contributing one channel, like switching off one of three lights. The layer below shows through in that channel, which splits the image into a complementary pair: red and cyan for R, green and magenta for G, blue and yellow for B.
Add a Hue/Saturation adjustment layer on top and drag the Hue slider. Both colors rotate around the color wheel together and always stay complementary.
It needs a clipping mask. Select the Levels layer and press Ctrl Alt G (Windows) or Command Option G (macOS) to clip it to the one layer below.
Yes. The final “Convert to Smart Object” wraps the layers rather than flattening them. Double-click the Smart Object’s thumbnail to reopen the stack, and double-click the Camera Raw Filter entry to change the finish.
Make the Duotone Double Exposure Effect in Photoshop Your Own
Two aligned photos, a black-and-white conversion, and one unchecked channel: that is the entire recipe. The Levels layer sets the balance, the Hue slider sets the palette, and the Smart Object keeps each of those decisions reversible.
Watch the video above to see every step in real time, and try the effect with your own photos. Portraits, dancers, and athletes all work beautifully.
