Lighting a 3D scene
You can adjust the default light for a scene, and add new lights. How you adjust the lights determines the shadows, the highlights, and the mood of the scene.
- In the 3D panel, select Infinite Light 1, the last item in the panel.
- Use the small knob to position the light in the upper left corner (at about the 11:00 position on a clock), so that there’s a tall highlight along the center of the neck of the bottle.
- Right-click (Windows) or Control-click (Mac OS) the light itself (the white round icon) to open the Infinite Light 1 panel. Then change the color to a faint gold color (we used R=251, G=242, B=203), and change the Intensity to 75%.
- Click the Add New Light To Scene button at the bottom of the 3D panel, and choose New Infinite Light.
- With Infinite Light 2 selected, change the color to a similar light gold color in the Properties panel. Then change the Intensity value to 30%.
- With Infinite Light 2 still selected in the 3D panel, move the knob on the on-canvas widget to position the light at about the 1:00 position on the clock, so that there’s a nice highlight on the edge of the bottle.
- Click the Add New Light To Scene button at the bottom of the 3D panel, and choose New Point Light.
- Select Point Light 1 in the 3D panel, and then change its Intensity to 30% in the Properties panel.
- Use the on-canvas widget to pull the light onto the center of the wine glass.
- Choose File > Save to save your work so far.
By default, Photoshop creates one infinite light when you create a 3D scene. When you select the light, an on-canvas widget appears to help you direct the light. Move the large knob to make sweeping changes; adjust the small knob for more precise lighting shifts.
