Applying the Duotone Effect

Customizing the Effect
Depending on the natural contrast of the image, you might need to move the sliders to ensure good contrast. This is particularly important when applying the effect to imagery of people, where skin tone varies greatly based on the subject. The effect can be flattering on all images when adjusted thoughtfully.
