![]() ![]() This will lighten the lightest parts of the image: Then, click on the white slider and drag it towards the left until you're just beyond where the right edge of the histogram begins. This will darken the darkest parts of the image. Click on the black slider and drag it towards the right until you're just beyond where the left edge of the histogram begins. Below the histogram are three small sliders - a black slider on the bottom left, a white slider on the bottom right, and a gray slider in the middle. In the center of the Levels dialog box, you'll see a large black graph called a histogram which shows us the current tonal range of the image. Use the keyboard shortcut Ctrl+L (Win) / Command+L (Mac) to quickly bring up the Levels dialog box. Step 4: Increase Image Contrast With Levelsĭisplacement maps tend to work best when the image you're using as a displacement map has a strong amount of contrast to it, so let's boost the contrast of our new document using Photoshop's Levels command. We're going to work on the duplicate "Lightness" channel document for a few minutes to prepare it for use as our displacement map. You'll now have two documents open on your screen, one containing the original image and one containing the duplicate "Lightness" channel. Set the "Document" option to "New" to create a new document from the "Lightness" channel. ![]() To convert the image to Lab color, go up to the Image menu at the top of the screen, choose Mode, and then choose Lab Color from the list: There's lots of different ways to do that, but one of my favorite ways is to use Photoshop's Lab color mode, which conveniently separates the luminosity (lightness) values of the image from the color. ![]() The first thing we need to do then is create a black and white version of our image. I like to think of it as Photoshop moving pixels from "dis place" to "dis place". A displacement map is nothing more than a black and white image which Photoshop uses to determine how to move and reposition pixels. Let's get started!ĭownload this tutorial as a print-ready PDF! Step 1: Convert The Image Into The Lab Color ModeĪs I mentioned, we'll be using Photoshop's Displacement Map feature to wrap the shadows from the blinds around the natural curves of the woman's face, hands and hair, so the first thing we need to do is create our displacement map. This tutorial is from our Photo Effects series. Here's the image I'll be working with in this tutorial:Īnd here's how it will look when we're done: We'll also be using a Color Balance adjustment layer to create a more convincing light source. In this Photoshop Effects tutorial, we're going to learn how to create the illusion that light is being cast on to the subject of your photo through window blinds, using a displacement map to bend and wrap the shadows of the blinds around the subject in a realistic 3D fashion. ![]()
