Graphic artist Erica Larson dreams up inspired designs every day as an associate creative director on the Adobe Studio team. In other words, she makes stuff that makes others want to make stuff.
What you'll need
Larson started by adding a Gradient Map Adjustment Layer (different from a regular Gradient). This allows her to map colors onto the grayscale values, while preserving the original image.
Click on different Presets in the Properties panel to see how each one affects your image. Larson selected the Violet, Orange gradient as her starting point.
Click on the gradient to open the Gradient Editor. This preset has two color stops by default. Larson double-clicked on each of the color stops, and then chose a new color using the Color Picker.
You can shift the color stops and the Color Midpoint (the center diamond) to add a bit more range to your image’s color spectrum. Larson went further, adding two more color stops by simply clicking just below the gradient, and again selecting from the Color Picker.
See how this dramatic, colorful effect can give any high-contrast, black-and-white image a bold new look.
