Task 3 How to Create Lighting Effects

The Lighting Effects filter casts multiple spotlights of different colors falling across the image as though it were a flat surface. The filter gives you full control over the focus and direction of the light, as well as the color, exposure, surface texture, and ambient light characteristics. Use this filter to add depth and drama to an image, as well as to build interest into a composition by highlighting a focal point.

1. Open the File

Select File, Open (or select Window, File Browser) and select the file you want to modify.

2. Select Lighting Effects

Select Filter, Render, Lighting Effects to open the Lighting Effects dialog box. You will see a thumbnail of the image on the left side of the dialog box, with one spotlight already placed over the image.

3. Reposition the Light

Click and drag the center of the light to reposition the light circle in relation to the thumbnail image. Then click the point where the light-source line meets the light circle and drag to move the light source. Finally, drag the handles on the light circle to widen or narrow the light beam as it is cast on the image.

4. Configure the Light Type

Modify the Intensity and Focus sliders as desired to brighten the image and focus the light beam. Click the color swatch to display the Color Picker so you can select a color for the light itself.

5. Configure Properties

The four Properties sliders control the appearance of the surface of the image as well as the overall brightness of the exposure. Adjust the Gloss and Material sliders to modify the surface brightness. The Exposure slider controls image brightness, and the Ambience slider controls the amount of secondary ambient light. You can click the color swatch in this area of the dialog box to modify the color of the ambient light.

6. Add Other Lights As Needed

To add other light sources, drag the light bulb icon into the thumbnail image. Reposition and reset the parameters as described in steps 35. The Style drop-down list at the top of the Lighting Effects dialog box contains many more fun options with which you can experiment. If you want to remove a light, drag it to the trash can icon at the bottom of the dialog box. Remember that you need at least one light source.
