Click this white box to use it. Properties Contains these options for the image you're shining the light on: • Gloss Determines how much the surface reflects light, from Matte (low reflectance) to Shiny (high reflectance). • Material Determines whether the light or the object on which the light is cast reflects more light. Plastic reflects the light's color; Metallic reflects the object's color. • Exposure Increases the light (positive values) or decreases the light (negative values). A value of 0 has no effect. • Ambience 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 completely diffuse the light source. • Color box Displays the Color Picker so you can change the color of the ambient light. Click this white box to use it. Texture Channel Contains these options for creating a texture for the image you're shining the light on: • Texture Channel menu Lets you select the red, green, and blue color channels in your image so you can manipulate how light reflects off of each channel, creating a texture effect. You can also choose to use the layer transparency of the active layer to create a texture effect. • White Is High Raises the light parts of the channel from the surface. Deselect this option to raise the dark parts. • Height Varies the depth of the texture from Flat (0) to Mountainous (100).
