The Lighting Effects filter lets you produce myriad lighting effects on RGB images. You can also use textures from grayscale files (called bump maps) to produce 3D‑like effects and save your own styles for use in other images.
The Lighting Effects filter works only on 8-bit RGB images in Photoshop CC. You must have a supported video card to use Lighting Effects. For more information, see this FAQ.
In the preview window, select individual lights you want to adjust. Then, in the upper half of the Properties panel, do any of the following:
- Choose a light type (Spot, Infinite, or Point) from the top menu.
- Adjust color, intensity, and hotspot size.
To duplicate a light, Alt-drag (Windows) or Option-drag (Mac OS) the light within the preview window.
Diffuses the light as if it were combined with other light in a room, such as sunlight or fluorescent light. Choose a value of 100 to use only the light source, or a value of –100 to remove the light source.
Applies a texture channel.
Casts an elliptical beam of light. The line in the preview window defines the light direction and angle, and the handles define the edges of the ellipse.
Use the Presets menu in the Lighting Effects workspace to choose from 17 light styles. You can also create your own presets by adding lights to the Default setting. The Lighting Effects filter requires at least one light source. Only one light can be edited at a time, but all added lights are used to create the effect.
Circle Of Light
Four spotlights. White has full (100) intensity and a concentrated (8) focus. Yellow has strong intensity (88) and a concentrated focus (3). Red has medium (50) intensity and a concentrated (0) focus. Blue has full (100) intensity and medium (25) focus.
Five Lights Down/Five Lights Up
Five white spotlights, down or up, of full (100) intensity with a wide (60) focus.
Red, blue, and green lights that produce a light of medium (60) intensity with a wide (96) focus.
Soft Direct Lights
Two unfocused white and blue directional lights. White has a soft (20) intensity. Blue has a medium (67) intensity.
- To create a preset, choose Custom from the Preset menu, and click the Lights icons to add Point, Spot, and Infinite types. Repeat as desired for a maximum of 16 lights.
- To save a preset, click Save, name the style, and click OK. Saved presets include all the settings for each light and appear in the Style menu whenever you open the image.
In the Lighting Effects workspace, the Texture channel lets you control lighting effects using grayscale images (called bump maps). You add bump maps to the image as alpha channels. You can add any grayscale image to your image as an alpha channel, or create an alpha channel and add texture to it. For an embossed text effect, use a channel with white text on a black background, or vice versa.
