40 • November 2018 • S I G N & D I G I T A L G R A P H I C S DIGITAL PRINTING AND FINISHING DIGITAL GRAPHICS Lighting Effects Photoshop's Lighting Effects filter has the capabil- ity of generating innumerable realistic effects to illu- minate your image. Lighting Effects is a Smart Object- compatible filter so after it's bee initially applied, you can use it non-destructively, and at any time during the workflow reactivate the filter to modify your settings. Before applying the filter, go to the Layers panel and choose Convert to Smart Object. The Lighting Effects dialog box is big and a little bit confusing. It has a lot of unfamiliar settings so let's take look at each feature. Figure 7: A Spotlight focuses the light on a specific region. Light Sources The Lighting Effects filter offers three types of lights to choose from. Spot—focuses the light on a specific region. A spotlight's intensity, direction position and rotation can be modified (see Figure 7). Point—is similar to a bare light bulb in an open space. Its location, intensity, size and color can be changed and the light bulb can be moved but it illuminates from a center point (see Figure 8). Infinite—simulates a distant light source. Its direction can be changed by dragging the widget that is displayed in the middle of the image. As you drag a little white circle moves outside of the image indicating the direction from which the light source is emanating (see Figure 9). Basic Lighting Effects Workflow Choose Filter > Render > Lighting Effects. From the Presets bar at the top of the interface, or the Properties panel to the right, choose a lighting style. Figure 8: Point is similar to a bare light bulb in an empty space. Figure 9: Infinite simulates a distant light source. Figure 10: Several lights can be applied, enabling the creation of pic- tures with multiple light sources.
