To modify surface lighting to adjust depth |
1 . | Choose Canvas Surface Lighting. |
2 . | In the Appearance of Depth area, adjust any of the following sliders: |
• | Amount — increases or decreases the visibility of brush striations in brushstrokes. The highest value displays more striations to create the illusion of more texture and increased depth, whereas the lowest value displays fewer striations to create the illusion of smooth texture without depth. |
• | Picture — controls how much color appears in the image. At its lowest value, all color is washed out, leaving only the highlights. |
• | Shine — controls how much highlight appears on the surface of brushstrokes. Higher Shine values make the brushstroke look metallic. |
