Making composites look seamless and realistic is the ultimate goal of a digital artist. In this tutorial, you will learn a simple and very effective technique for matching the degree of saturation of your background and subject.
Antti Karppinen is known for creating beautiful storytelling imagery. In this video, he demonstrates how to match the saturation of a subject to the background on which it will be placed. Karppinen notes that it is difficult to perceive differences in the degree of saturation by eye, and he walks us through a quick Photoshop technique to take the guesswork out of achieving consistent saturation.
Karppinen uses a Selective Color adjustment layer and sets the color sliders to 0, and the neutral sliders to 100. This generates a black and white saturation map of the overall image, with white areas indicating regions of high saturation. Once he is able to visualize the areas needing a saturation adjustment, he creates a Hue/Saturation layer that is clipped to the layer containing the subject. In this example, the saturation of the subject layer is decreased. Using the Info tool allows him to precisely assess the saturation levels of specific areas in order to match them accurately.
Blending components of composite images to create uniform tones and saturation will help them to appear realistic and professional. This technique is a quick and easy way to measure and adjust the saturation of any image you wish to create.
