Most layers on a design have a Contrast setting that you can use to control the difference between the light and dark areas.
Increase the contrast to make dark areas get darker and light areas get lighter.
Decrease the contrast to reduce the amount of difference between the dark and light areas. This can create a softer, more faded look.
For example:
Image 1 has low contrast on the background layer and has a lighter, softer appearance.
Image 2 is the original image with no contrast applied.
Image 3 has more contrast on the background layer, creating a darker, more dramatic look.
To use Contrast, open a design in the editor and then select the layer you want to edit. Look for Contrast in the Adjust settings. For detailed instructions, see Adjust the visual properties of a layer.
