Vivid Light is another blending mode that lightens or darkens according to the brightness of the blend color, but the result is even more intense than Soft Light and Hard Light. If the blend color is more than 50% brightness the image is dodged (lightened) by decreasing the contrast. If the blend color is less than 50% brightness, the image is burned (darkened) by increasing the contrast. 50% gray has no effect on the image.
One practical use for the Vivid Light blend mode is to add a punch of color to a dull photo by duplicating the image in a new layer, setting the blend mode to vivid Light, and lowering the opacity to achieve the desired result. It can also be used to create more dramatic lighting in a scene.
