Use Adobe Photoshop to create a duotone effect.

Whether it’s your favourite band’s avatar or your best friend’s new profile pic, the duotone effect is everywhere. Thankfully, it doesn’t take a full studio to create—all you need is your creativity. Learn how graphic artist Erica Larson uses Adobe Photoshop to add colour gradients to her images, creating a duotone look.

Before you start.

The duotone effect works best on high-contrast images. Use this sample image if you’d like or practice with your own.

Step 1: Prep your image

Larson started by adding a Gradient Map Adjustment Layer (different from a regular Gradient). This allows her to map colours onto the grayscale values, while preserving the original image.

Step 2: Add a splash of colour

Click different Presets in the Properties panel to see how each one affects your image. Larson selected the Violet, Orange gradient as her starting point.

Step 3: Choose your shade

Click the gradient to open the Gradient Editor. This preset has two colour stops by default. Larson double-clicked each of the colour stops and then chose a new colour using the Colour Picker.

Step 4: Enhance the spectrum

You can shift the colour stops and the Colour Midpoint (the centre diamond) to add a bit more range to your image’s colour spectrum. Larson went further, adding two more colour stops by simply clicking just below the gradient and again selecting from the Colour Picker.
